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?
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.
No, and No.
You want to read the article linked above.
We don’t do that here
You should definitely read the linked article. You’re right about it being for your car, not your phone, but seriously, read the article.
Is the infrastructure relevant though? As I understand it, the battery is charged by splitting water (H2O) into Oxygen and Hydrogen atoms (instead of H2 molecules, hence the name proton battery) and instead of compressing and cooling it, having a solid structure in which to store the protons. When drawing energy from the battery the opposite process takes place. So basically it is both an electrolyser when charging and a classic fuel cell when discharging with the storage of hydrogen (protons) being integrated in the same battery through a porous solid (mainly carbon). To quote from the article: >It looks like more of a battery competitor than a fuel cell competitor, though.
Next to the advantages they cite (energy and power density, abundant and environmentally unproblematic materials, recyclability, not explosive) I do wonder about the density in terms of volume. If they are bigger in size, they could constitute a better solution for big energy storages within the grid or at home, where now many are using lithium ion batteries.
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
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
The battery uses dark matter, it’s effectively an alternative to nuclear fusion, so the use case would be in space stations rather than yout phazer set to stun.
From what the article said, most definitely not. But, it doesn’t look very complex in terms of scaling / manufcaturing it and they say they want to get it to market quickly.
