edit I am an idiot, who uploaded the image link as the URL. The original source should now be accessible

RMIT engineers say they've tripled the energy density of cheap, rechargeable, recyclable proton flow batteries, which can now challenge commercially available lithium-ion batteries for capacity with a specific energy density of 245 Wh/kg.

Does this exist as a consumer product yet?

[–] lzbz@programming.dev 2 points 1 year ago (8 children)

This is a research paper, so it's gonna be at least a couple of years until ot could be seen in products. However the battery uses hydrogen, it's effectively an alternative to fuel cells, so the use case would be in vehicles rather than yout phone. That being said, hydrogen fuel infrastructure is almost non-existent right now.

And you basically have 2 options for hydrogen production: oil consuming and GG-emitting steam reformation, or energy intensive electrolysis of water, unless there's another i don't know
