It was hard to find information about what they do actually, but I found some information in this article on their blog:
Instead of using lithium or cobalt, Flint’s battery uses zinc and manganese—two of the most abundant and sustainable metals on Earth. And the core of the battery? It’s made of cellulose paper, which is biodegradable.
So this is a Zn-Mn battery, they just use a cellulose based electrolyte. If you search for “Zinc Manganese” you will find a lot of research papers from the last couple of years.
The conclusion of one of the papers:
The second [challenge] is to increase the areal capacity of cathode materials. Recently reported doped MnxOy cathodes only demonstrated an areal capacity of 0.1–0.2 mAh cm−2 due to the relatively low mass loading, which is far below the commercial standard (>2 mAh cm−2).
So it’s energy density should be an order of magnitude lower than current battery technology.
It doesn’t sound as revolutionary, but a step in a good direction.
Rarely you read about a revolutionary battery that is not vaporware. With the amount of alkaline batteries in world, I really hope these pick
sup.This is nuts. Conspicuously absent is price, though. Gonna start at five bucks a cell or something?
What I found the problem won’t be the price, but the energy density. These batteries last
10 times less thantenth of a current one.Ten times less? Do you mean a tenth?
Yes, I found that in a research paper about Zn-Mn batteries
They claimed the density was comparable, though.
Where do they claim that? I only see they claim that the lifespan is comparable, and the price per kWh will be lower. It’s a rechargeable battery so lifespan means recharge cycles.

Oh thank God. Thank you so much for some uplifting news! With all the worldwide BS going on, it’s unique to see something to feel good about. I feel like I haven’t drank water in a month and you just let me wet my mouth.
Will they not leak? I have lost too many devices because the battery leaked. I don’t use my tent light often but I need it to work when I’m in the middle of nowhere
