So from my understanding so far I start a channel and people do their video on there own channel and send a link to the community channel and it’s up to them if they want there own Chanel setting to be public or private or they can chat on the community tab if I can get it . Does that make sense ?
In regards to the double displacement reaction .... I was thinking along the lines of there being a stronger bond taking place . So the end result is the number of ions in the zinc and chlorides balance out better with that of the ions in the potassium and the hexacyanoferrate
If anybody can think of a simpler way or a better way ! I would like to set up the new community tab as well if I can so we can all chit chat etc .so that we are not bombarding Kevs channel like we are now 😂😂😂
Once deionized water is exposed to the air it absorbs CO2 to form carbonic acid this can alter the ph from 7 or 8 down to as low as 5.6 so deionized water is never neutral ph in air. It maybe this weak acid that causes your water battery to work.
Ok Tim the next time i do this i will start off with a sealed pouch and i am also going to try pure Distilled water along with the purest paper for the separator😊
Lithium batteries use activated carbon coated with a non-polar low viscosity solvent. Suspended electrolytes and carbon species form a solid electrolyte interphase layer on and within carbon nanoparticles. Charge conditioning pulls the electrolytes into the carbon pores creating the interphase surface. Capacity would be a function of the fractal dimension of the coated carbon surface divided by some index of the SEI thickness.
Ok Ken i am just a Layman, i'm not a chemist nor a scientist, not even a mathematical genius. So i have read your comment 4 times now and for the life of me i just cannot see what your point is here. So for all of us amateurs could you explain please. P.S great little vehicle you have there 😎
@@mouldykev well, like most of us I'm looking for something better too, and I very much appreciate the time and effort You and others like Robert Murray Smith and Cayrex2 and others have shared. I have some limited experience a few years ago with a stainless steel Capacitor/Battery that continued to produce microwatts even after being shorted. I logged and plotted.the decay a few times. And that time I chalked it up to ionic entrainment. Perhaps the distinctions between a capacitor and a battery really belong in a vacuum. Thanks for checking out and commenting on my Velo. Hope we can talk a little more about DIY electrochemistry.
Happy holidays. I will give you the same suggestion I gave Robert. Lay the graphite out on a piece of parchment paper for cooking (Teflon plates would be ideal but paper is cheap) then powder coat over the thin layer mechanically applied. Pop in a oven at 350 degrees until it glazes, remove and cool then peel away a compressed and layered graphite sheet somewhat ordered by high voltage.

Hi Kev! This is John up here in Tennessee. I am the cotton Candy machine guy. Just an update to let you know that I ordered a 29 dollar cotton candy machine off of Amazon. I was just sleeping and had one of those middle of the night dreams. I was just thinking of using thermo plastic to make cotton candy binders for active material, when this idea came up: WHY would a binder be needed when you can just use the cotton candy and activated charcoal to begin with? I was thinking of how sticky cotton candy was and how sugar itself crystallizes and carbonizes when burned. Ok, so I thought or saw in my dream finely crushed activated carbon or carbon black or perhaps graphene mixed with sugar spun into cotton candy, and then packing that into a silicone mold the shape of my plates. This would then be microwaved to carbonize the cotton candy matrix. You would then have a carbon matrix physically supporting your active carbon materials? Now you would have no problem with filling the voids in the carbon and clogging up the works. The same type of thing would also make very porous separator material and could support any additives you desired. If the sugar were to be sufficiently carbonized in the microwave or a kiln, then I don't see why it wouldn't stand up to be whetted by a water based electrolyte? Kev, Could I ask you to contact me privately somehow?
5:50 I've always wondered about the possibility of the binder filling the pores, and by chance I always mix the carbon with water first anyway. It'd be interesting to see an analysis of both to see what kind of difference it makes.
Sometime in January mate all being well, i am doing my sums at the moment and i do say more in a newer vid ( maybe today ) so trying to come up with a price.
You're right on the money with the controllablility of a microwave kiln. I've been using a battery powered thermocouple (k-type) to read the temp at different settings and then select the setting i need thats in the range of my reaction XD since i am working with just caronbs it hasnt been that big of a deal. But i am current building my own refractory kiln now. Just bought the Kanthal and PID, now need the Air-blower tube to exchange different gas atmospheres.
great info shared, i had same problem with electrolyte. mine is based on H2So4 and i do soak my carbons in it overnight before i do the assembly and test. amp ratings from normal practise 150-250mAmps if you do the pre-soak they can jump to 1.5Amp
Barry Liebenberg you want to soak them and pull a small vacuum on it to really get the exchange of air and electrolyte going on . You will see a big difference . You can pull a vacuum with a tube and bottom of coke bottle cut out .
Hi Kev , if you feel this is inappropriately placed here I will remove it mate . Hi all , as Kev has stated , it’s apparent that there are many people watching and learning and probably doing some experimenting here and there just like myself . I keep meaning to start uploading content but never feel I have enough content to feel its worth it and I feel many of us may be in the same boat . I think uploading would still be well worth it and benefit many viewer as we all show some info that someone can learn from so I am proposing to start a battery community channel that anybody that’s subscribed too can post there content as well . I am not sure how this would work and am canvassing the idea at this point and welcome any input and if anybody know of a channel on TH-cam that does this kind of thing , then send through a link . It will be of great benefit to all interested as the collective information becomes open source and the rate of development will be much accelerated to overcoming hurdle in battery technology .

You've outdone yourself with all the info in this one Kev. Thanks, for adding to my work load of things to try! LoL. I am trying out a new battery tester module that I recently bought. I have the EBD - USB one you've shown and like it but this new one will charge as well and repeat charge/discharge for as long as you want on its own and has a temperature probe. Its more expensive of course but still reasonably affordable for what it does. It ranges from 175 USD to 375 USD. 375 USD for the full kit. Here is the link if you are interested in checking it out : www.batterymetric.com/mk-modules/ Bill
Dear Wiliam Hada, thanks for the link. But: If you use the Monitor Mode by EBD-USB and a stabilisated power supply you can record the load as well. And make phantastic Statistics via export of Data using a spreadshit like Excel. In the Link you gave is not shown any Data Recording ... So I'm afrait the items from ZEK are better. Sorry about this ...
@@scantrain5007 The module comes with nice free software that logs your data, reads out power values, records temperature, and prints reports etc.. I guess they don't make that clear on the web page. It also allows you to program charge\discharge cycles and also rest/recovery cycles where it just sits there waiting for the next cycle.
Is it PTFE 210 that you use? Cause I am having trouble dispersing PTFE in nmp, propanol, e.g., dmc etc. Not sure if my PTFE is bad. I believe I have t use a fluorinated solvent... What you using for solvent?
@@mukundsrinivas8426 I disperse into Ethanol mate, so i cant help ya there. A 60% solution of PTFE to 95% ethanol or anhydrous. Works brilliantly, only need like 50µl per 6grams of actives for batteries and such. Adding this to a gel of CMC seems to work well also, i gel with a water diluted ethanol, so as not to denature the CMC .
Awesome very informative new white board style Kev!. Def helps to getting those important details across that are often quite hard to get across at times, and your great at doing it too!. I use white boards most weeks to brainstorm with various teams of peeps, explain complex stuff. Working on all sorts of solutions to various challengers and certainly couldnt do without them or a chalk board if nothing else. Nice new conductive sheet youve made their!, quite good conductivity results so far too. And your totally right that if you can coat some foils (or even thin metal sheets or meshes) with this same material, then the world should become your oyster (Ps making sure the foil and conductive coating interface is completely non porous to prevent electrolyte corrosion or oxidation etc), Onwards and upwards, once again cheers for the mention P :) (y)
Ps So thin film non porous conductive coating on metal foil, sheet or mesh first ideally, then followed by ones thicker ion & charge storage conductive micro porous coating on top of this, should do the trick particularly well ;)
The Urea carbon-bond mechanism is using CH4N2O and binding it to OH- along the carbon chain. This links the CH4 groups together and stores the charge via protonation of the urea with a hydroxide radical. Upon discharging the urea breaks up to form regular urea and water, disconnecting the OH- bridges. This allows charge to settle as the OH- cross' the separator.
WoW Arthur so glad to hear your voice again ( in text LoL ) hope all is well your end ! But yes i am at my computer right now editing new video's unfortunately it is going to be part 1,2 & 3 because they are so damn long ha ha but all new interesting stuff happening and 2019 should be a showstopper mate stick with it.
