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.
Others downvote you and say “read the article”, but not giving arguments.
I read the article and it is not clear what is the advantage… looks like less pressure is needed than other types of hidrogen cells, but there are no details.
I agree with you, don’t hold your breath for this. All details would be in first sentence if there was any chance of this becoming reality.
The advantages are, every part of the device can be easily recycled, and the parts to make the charge-holding portion of the battery are less damaging to acquire than in li-ion
