As you know by now mate, I often have additional questions and suggestions after each video, but I have to say, well done Rob! Fantastic video. It had everything: Time for the theory, real world example in practice, along with instruction as to how to replicate! Probably one of your best right there!
You are quickly becoming my favorite person on TH-cam (masses of people are wasting the best invention, information on the internet!) You can learn or do anything now if you use creativity and your brain. Thank you for your contributions
Not bad, loved the video, thanks! In the RAF around 1979, there were batteries in survival equipment /kits (such as life raft kits), that had batteries that you submerged into the ocean (seawater). We were told that these were used to run a flashing distress beacon, and used saltwater as an electrolyte. Not very powerful, of course, but it could save your life by alerting search aircraft to where you were!
Outstanding presentation Robert as we should be more aware of the ways we can store energy in a safe manner without destroying the world we live in. Please keep up the good work and thank you.
The Disposable batteries probably wouldn't be so popular if, they didn't hold such a high amount of mAh per charge versus the rechargeable batteries. Most "small" rechargeable batteries do not have a high mAh per charge. They are superior in mAh per lifetime of the cell. Great video Robert! You are a encyclopedia of knowledge & a inspiration to us all!👍
Thank you for sharing, a very nice find on this newly published paper. There are literally hundreds of avenues of optimization on the foundation this paper describes.... application-specific / form factor avenues, processing, materials / recipe...cheers!
Reminds me of the so called stone paper made with 70% Calcium carbonate and 30% HDPE. It immediately made me think about its applications for battery making
If I'm understanding it correctly, someone could in theory insulate each side with a biodegradable wax or wax paper, roll it tightly, and somehow activate the electrolyte when ready use, would have an AA battery for 2 hours that's entirely biodegradable and cheap? I like it. Sounds like it would be invaluable to underdeveloped countries

Bob , Many years ago at sea we had lifejackets fitted with small lights . The battery powering these only came to life when immersed in sea water..........
I love these home-made battery videos! I never get tired of them. Especially the ones made from cheap, easy to find materials. One of these days, I want to build a home made battery that can charge my phone, and be recharged with solar or some other novel device.
Great video! I really loved that you edited the instructions over the video. I try and take notes when I watch and having it all written out is so helpful. Much appreciated Rob.
You're right on about amazing paper. I visited a paper mill years ago and it was beyond belief what goes into paper production. The mill is a multiple story building and blocks long. They grow there own special trees and do great job being good to environment. Sad that we live in a world lead by pervayors of completely false history; the true origin of paper battery being but one example in a mountain of deception. Greed will protect the AA battery, and unlikely heroes will make the scene rescuing us claiming undeserved credit for things that have been around for 100s of years.
So true , the cover-ups are endless to keep 7.4b rolling out.. Great video Rob love them ❤ Have you tried freezing a dead AA or 9v battery for a week in freezer in a snap sealed bag ? To bring it back to life ..
Robert great video sir ..The issue i have with off the shelf rechargeable NIMH batterys like AAA and so forth is the lower voltage in some cases hurts performance of what its running but thats that
there are, or at least WERE nickel zinc batteries with a 1.6v terminal voltage, i'm using some in a digital camera which doesnt like nicads/nimhs due to the low voltage, but eats normal alkaline ones pretty quickly , i got 4 of them some years back , unfortunately 2 have since failed after only a few charge cycles, gone 'open' maybe this is an issue with them? limited shelf life? i have no idea as yet if theyre still available, i hope so as would like to get a few more, you have to use a charger designed for them as nicad/nimh type is not advisable as simple types will overcharge them (may be possible to mod them), 'smart' ones likely to reject them as 'bad'
First, thanks for great video Robert. Second, I like the point that you made about Standford. 😁 I share your experience on that. Third, keep up the good work. People like you are what made your your nation, continent and human kind great.
I agree paper batteries have been around for a long, long time. I built one for a school project back in 1974. We utilized paper in a plastic bottle, mine was D cell size.
Yep, if this catches on, we will completely exhaust the element Zinc. Still a great experiment, but just as you said, this is nothing new. Where do we take this? The resulting battery size to compete with a AA would be as big as car to power that clock for a standard year. I am 1000% with you on the battery in the landfill problem. Oh, can you explain how zinc becomes biodegradable, please? I could make a fortune growing zinc.
Where are you with your old paper pouch batterys? I don't recall a conclusion to that production. I struggle to remember with what chemistry, but I always fancied making long Peper batery rolls, housing the cells in pipes and those in 45 gallon barrels. Haven't gotten round to it yet.
Great. Just as aside, I am curious to know if you could get a current from using say aluminium beer cans and scrap iron immersed in seawater ? I don't have any testing equipment myself.
There's a paper about making a battery out of paper. This paper inspired us to make paper batteries. Paper is recyclable and biodegradable. Both the premise and the physical structure of this project have alot in common, strangely enough.
I use NiMH cells because they are very leak resistant so I can leave them unattended and not worry much about my devices having leaking battery issues... also their incredible cold weather performance and insane power density compared to other AA cells are also nice to have. But this is still interesting since paper is a wonderful material and NiMH batteries are typically not very cheap to make or flexible... things that paper batteries are good at... though NiMH total cost to own is still cheap since the Japanese made cells are rated to go for 2000 cycles. But still, paper batteries like you show being water activated might be really really good at emergency batteries that are shelf stable until activated by getting them wet.
Would there an efficient/effective way to reclaim the zinc? Presumably the rest of the materials are totally compostable, but I imagine an accumulation of zinc in any one place might not be so good?
Interesting, few plastic tubes of different battery sizes with conductive ends, slight change in the morphology, few mL of electrolyte, push in a pre-rolled dry cell, pop the top on and presto your own AA battery or whatever. Remove roll when dead, more electrolyte another roll and on your way. Take the old paper, put in an electrolysis cell recover the zinc and away you go again. Very nice, bugger off disposables.
Can't wait to see what you to come up with as an improvement Rob. Hmmmm all things being considered it may be a bit of a challenge . Best thought i have is using already used office paper or finding industries that use large amounts of paper like news print. Not so sure news paper would be strong enough although after being painted it might be fine!
Dear Mr. Smith, i have seen that you use the extension cord fully on. I can ask you to take it all out because like this can be a problem, it is a coil on a(at least) 2000W consumer. I have burned one because of that.
Wow! That's neet! I'm going to download the paper and give it a try. I build my own battery packs for E-bikes, so I'm wondering if this will ever progress to rechargeable batteries that could run an e-bike. Well, thanks again for another excellent video and head scratcher! 😎👍
Has this enhanced the efforts on your battery? I find your method could be improved by these mixtures due to hemp having a higher potential surface area than pressed paper.
I haven't bought disposable AA or AAA in ages. I use rechargeable ones and downgrade them as they grow old (ex: from flashlight to radio, from radio to remote etc), finally packing them up with other batteries to a send them once a few years to a local battery recycler handler.
To turn it into a AA form factor, I assume you would roll it up. Would it short circuit if you rolled it up? Would another piece of paper on top stop that from happening?
I am reluctant to do that as it would mean you would think you had to buy the ink - the in would work well but I also want folks to see they don't need the ink if they don't want it
It might be possible to roll up the paper into a tube or stack multiple sheets of paper with sort of insulation between them to increase the voltage, though I am a little concerned of arching with a load of paper in a area
Hi! Long time viewer with a question regarding this video. Do you think it would be possible to treat the carbon black with Dilute solution of potassium premeganate to make Nano particles of manganese dioxide. As for catalyst. (Somthing you taught me on magnesium battery video)
Great vid, again. thank you, my tuppence (two pence) worth.. Whilst rechargeable AA's remain pegged at 1.2 volts, 1.5 volts like Alkaline will continue to dominate. Rechargeables are fine for remote controls with slow, infrequent draw. Things like passive infra-red detectors on LED lighting units, RFID/ electronic keypad locks (which auctuate via a motor), wildlife cameras etc.. etc.. the voltage needs to be quick for optimal performace. despite being the same current in most cases.
?? You 'll find rechargeable delivering way higher currents than disposables but they self discharge faster. For occasional light use disposables seem more convenient.
@@jochenschrey2909 we are at odds lol. not intentionally. i find with 1.2v the mah (rechargeable) generally, is greater at first. But slowly gets less and less as discharge occurs. The 1.5v mah tends to be almost constant. i speak from my experience and not from any kind of scientific standpoint.
@@Palmit_ ?? once again. "mAh" = capacity, for example number of flashes you 'll get from a charge. I was talking current, "A", formexample recycle speed of the flash gun, performance during quick recharges, like a 4/6/8 minute RC car race
there used to be, dunno if still made, nickel zinc cells with 1.6v terminal voltage, i'm using 2 in a digital camera as it eats even good alkalines and doesnt work for long if at all with nicad/nimh, i got 4 of these nickel zinc things from maplin(uk), when on offer, probably 10 years ago, maybe more, and only started using them last 2 or 3 years or so, 2 failed fairly quickly after a few charge cycles, so maybe their shelf life isnt good.?? last 2 still working, so far, hope they are still made so i can get some more! i also have 4 AAA size ones, as yet not used
Hi Robert! I've managed to replicate the battery setup and achieved a voltage of 1.42V on the potentiostat. Could we discuss the paper further? Greetings from Brazil!
Excellent video and ingeniously simple technique! Could you please do a video on decomposition of polymers by microwaving, where the by products are pure hydrogen and multiwalled carbon nanotubes?
@@ThinkingandTinkering Thank you very much Mr. Murray-Smith! Below I am providing the original article name which I came upon a couple of years back. I figure it would be a interesting and important knowledge to spread. I believe this would be the most cost effective way to produce H2 gas, but I leave it up to you! "Microwave-initiated Catalytic Deconstruction of Plastic 2 Waste into Hydrogen and High-Value Carbons"
A great little battery Rob :-) Whatever happened to your paper battery you was making some years ago? I can remember you had a pile of paper cells that you had made and taken days to assemble.
Wouldn't it be lovely if someone made a rebuildable AA battery sleeve, little stainless thing with a thick graphite rod in the middle to wrap your paper around!
what type of paper is best for this stuff? there are literally thousands of types of paper for different purposes starting from arse wiping with varying success rate, all the way to looking really posh... is the paper binder chemical important?
yes,apparently that is the main fertiliser (mn) & I guess some potassium too. I wondered about other toxics in there but it doesn't seem to be a concern. great channel btw!
How about making a few hundred and stack them in parallel and series, see if they can be scaled up for lighting or a fan. What about the paper density and composition, also it's thickness and the coating thickness and some of the ratios of the various chemical components. When you stated common table salt, is that non-iodized? Also did you use distilled water? I'm curious what is the weight of the end product and it's scalability?
I tried to make the anode and cathode inks with the proportion given in the paper.I found out that the inks become very dense and have high viscosity. How can we make the inks less viscous?
If these can run in series and are rechargeable I'm thinking plying and gluing to the back of solar panels to supply 24/7 power without the bulky Li ion box.
The duration can be extended considerably and a study of the alkaline pulping process would reveal the detail. But such an old information comes from an innocent time and would be counter productive in terms of recycling.
I'm curious... would you be able to stack these paper batteries together using whatever parallel/series connection you need to power an 18V cordless drill? Is it stackable? Will the higher voltage and current alight the battery? If it does catch fire, will be a big fire? Little fire? No fire? How does it work in cold temperatures (freezing) or hot temperatures (inside an oven)? Can it handle inrush current? Can they be recharged? Or can they be modified in some way to make them rechargeable? It would be an interesting video if you could tackle all these questions...
doubt it'd have enough current capability, as its a variation of the standard zinc carbon type, which have poor current driving ability, voltage wouldnt be a problem, within limits, as you could connect as many in series as physically possible....charging, very unlikely as zinc carbons cant be, inrush current? not sure what you mean, except peak current capability? as said, current very poor....
This is mind blowing!! I've got to imagine if you put a layer of insulation on top of a shower, you could roll it up and slide it into a sleeve, thereby condensing it. If you were to run these in parallel, I also imagine you'd get significantly longer life out of them too
You'd need a lot of them. At least 35 I'd say, of the size he made, connected in combinations of series and parallel, to charge a cell phone just once. Good luck getting all the connections to remain solid.
Just curious how many times the battery would be rechargeable. The paper mentions that they will get to an evaluation in the future. Just curious about the forming of dendrites which was mentioned earlier in comments. Fun project to build for a summer holiday I would say.
One could argue that paper batteries go all the way back tot he first ones. (well after the bagdad ones) The Volta Pile was paper between copper and zinc disks.
@@ThinkingandTinkering many years ago when i was little i made 'batteries' from stacks of 2p coin-paper-10p coin, one on top of another, with salt water electrolyte 😉 powered leds ok, cant remember if i tried a small radio or not , with modern high brightness leds it'd be much better

How about making a few hundred and stack them in parallel and series, see if they can be scaled up for lighting or a fan. What about the paper density and composition, also it's thickness and the coating thickness and some of the ratios of the various chemical components. When you stated common table salt, is that non-iodized? Also did you use distilled water? I'm curious what is the weight of the end product and it's scalability?
i suppose seriesing and parallelling possible, but practicality may be an issue, instead of parallelling, larger flat area, maybe?,
Thank you for the video and history lesson
glad you liked it mate
I tried to make the anode and cathode inks with the proportion given in the paper.I found out that the inks become very dense and have high viscosity. How can we make the inks less viscous?
Thanks Rob.
cheers mate
If these can run in series and are rechargeable I'm thinking plying and gluing to the back of solar panels to supply 24/7 power without the bulky Li ion box.
The duration can be extended considerably and a study of the alkaline pulping process would reveal the detail. But such an old information comes from an innocent time and would be counter productive in terms of recycling.
I'm curious... would you be able to stack these paper batteries together using whatever parallel/series connection you need to power an 18V cordless drill? Is it stackable? Will the higher voltage and current alight the battery? If it does catch fire, will be a big fire? Little fire? No fire? How does it work in cold temperatures (freezing) or hot temperatures (inside an oven)? Can it handle inrush current? Can they be recharged? Or can they be modified in some way to make them rechargeable? It would be an interesting video if you could tackle all these questions...
doubt it'd have enough current capability, as its a variation of the standard zinc carbon type, which have poor current driving ability, voltage wouldnt be a problem, within limits, as you could connect as many in series as physically possible....charging, very unlikely as zinc carbons cant be, inrush current? not sure what you mean, except peak current capability? as said, current very poor....
I find all your stuff real interesting, always watching it at work, i would be interested in any you have or could do on hydrocarbonization,
Always Quality stuff !
This is mind blowing!! I've got to imagine if you put a layer of insulation on top of a shower, you could roll it up and slide it into a sleeve, thereby condensing it. If you were to run these in parallel, I also imagine you'd get significantly longer life out of them too
Can it be recharged with water or is the zinc creating a galvanic effect
the zinc get eaten away as its 'working' as with all zinc carbon cells,
This might be great for a long-term storage method to use as an emergency recharge of a cell phone as long as you had a simple voltage regulator.
high power zener such as a 1N5338 5v1 5w in parallel will clamp it ...
You'd need a lot of them. At least 35 I'd say, of the size he made, connected in combinations of series and parallel, to charge a cell phone just once. Good luck getting all the connections to remain solid.
I wonder if layering another paper on top of it and rolling it up improves the performance
What did u use to charge the alarm clock to the paper battery?
bloody brilliant as usual
Could you just print the whole thing by adjusting the composition of toner? Color laser printers can handle 3 different toners.
Brilliant!
OK.. That was cool.. Thank you..!
Glad you liked it!
Finally gets to the point at 2:23
Just curious how many times the battery would be rechargeable. The paper mentions that they will get to an evaluation in the future. Just curious about the forming of dendrites which was mentioned earlier in comments. Fun project to build for a summer holiday I would say.
probably 5 or 6 times but it might be better - hmmm lol
One could argue that paper batteries go all the way back tot he first ones. (well after the bagdad ones) The Volta Pile was paper between copper and zinc disks.
I thought that too - but I thought I might be stretching it a bit there lol
@@ThinkingandTinkering many years ago when i was little i made 'batteries' from stacks of 2p coin-paper-10p coin, one on top of another, with salt water electrolyte 😉 powered leds ok, cant remember if i tried a small radio or not , with modern high brightness leds it'd be much better
Another awesome Battery video Robert. I just wonder, 'could you do a video over a Rechargeable Paper Battery? My brothers Sail Boat comes to mind, and this type of Battery maybe the solution I've been looking for. Thanks again for your good Heart in sharing your hard earned knowledge with me.
This looks good on paper - - - and on your voltmeter too :) .
