Hello to all TPCR members
I took the initiative to revive @SteveS’s thread on TPCR, starting with a fascinating article about quantum batteries and superabsorption.
Superabsorption unlocks key to next-generation quantum batteries (phys.org)
Quantum batteries closer with superabsorption breakthrough (cosmosmagazine.com)
As usual with Quantum mechanics, this is a bit complicated to comprehend!
Next up, iron-air batteries (but probably not for mobile applications?):
These batteries ditch the lithium for something much cheaper: iron (msn.com)
Those scientists are making batteries with hemp fibers, ‘better than graphene’,

but also with all flavours of biowaste - from peat moss to eggs. Most recently, they turned banana peel into batteries.
Apparently, we are getting closer to this

Proton based battery…
May replace hydrogen fuel cell and also lithium-ion batteries, while beeing cheap to produce and much safier than both… Interesting…

A new Cobalt-free battery by Toshiba
Good find!
It looks like they may have at least partially solved the relatively fast degradation issues (limited number of charge/recharge cycles) which have kept them back to this point.
New material for supercapacitors, 4 times more efficient, discovered with the help of machine learning:
New solid state battery principle, that could be quite relevant for smartphones and tablets:
I think I’d rather have an atomic battery:
