This is the fixed video with corrected nickel oxidation states. For folks who subscribe, I apologize for the duplicate videos.

[@ryanatkinson2978]

This is super cool, and the fact you're making this all open source and explained well on TH-cam is really great. Thank you!

[@kennethanderson7642]

This is excellent work. Thank you for following through and bringing this to a satisfying conclusion.

[@FBPrepping]

Thanks for this Peter. I´m a metallurgist, and for years I´ve been willing to build some affordable DIY batteries to deal with the frequent outages in my country (Venezuela). It´s sad to see some of my acquaintances (like one Dr. in Electrochemistry I know) that instead of using their knowledge and skills in something productive preferred run away to live in other countries. I´m going to check your papers and once I can build my own, will upload the results in my channel.

Thanks for all your work! Me and my Dad are making this a wee winter project

[@zonta71]

The blessings of Open source. Thank you for the videos. checked the other videos after seeing V2.0. thats is a substantial increase in capacity Sir. Congrats. So a 40ft container is 76Kw capacity. getting that down to 20ft might actual get some diy folks in the offgrid community to attempt a build. congrats again on peer review papers. 1luv

I wish you a bright future in the field of iron batteries

[@czechyorker]

This looks promising. Thanks for the update.

[@archivistdeveloper4058]

Excellent work. I look forward to seeing more.

The price of nickel is not that high. For large stationary energy storage applications, an iron-nickel battery would be a good reliable solution.

[@1kreature]

Awesome work! 2 more orders of magnitude and it will be only considered "poor" energy density.

[@simonlinser8286]

great stuff thanks for your work!

[@johnslugger]

You can simply use one Iron Cathode and one Carbon Anode in the Edison Battery if you use Nickle Potassium Sulfate as the electrolyte.

[@Buzzhumma]

Oh Peter, dont go matey. I really liked watching this development from a professional scientific perspective. It was great. I hope you go on to developing something else that we can all learn along the way . I know all good things must come to an end but just not education. 👍🏻

Thanks for open licencing this. If cost per wh is the overriding factor this sounds like a winner, although 1000 cycles is a little on the low side. For a solar setup I would probably prefer supercapacitors, available off the shelf for under a buck per wh but with superior endurance of ~20,000 cycles.

Ni-Fe batteries are incredibly robust, a forklift used at a electroplating shop that dated back to the 1920s still worked despite the battery and the frame being the only truly original parts 😮😮😮

[@rescueteam5]

Good job. Good Luck

[@ParadoxPerspective]

Good science! You should consider a collab with the Tech Ingredients channel.

[@AlexthunderGnum]

Awesome. Thank you!

[@miguelangelsimonfernandez5498]

Excellent, thanks.
