Graphene could be better.

Unless ((they)) supress it.

Nah nigga

Just recycle the old batteries. Devices will get more power efficient anyway.

Nothing can touch oil. (Of course, I'm not saying that it won't ever be replaced.) Why? because it's remarkably dense in energy while also being easy to handle.

Isn't the cobalt component the most expensive material in Li-ion cells?

>Just recycle the old batteries.

Recycling currently costs more than making new from mined material. They also have the tendency to explode when stuck into a shredder like how lead-acid batteries are currently recycled. The best we can do is store old cells until it is economical.

>Devices will get more power efficient anyway.

Any power efficiency gains are spent on more CPU grunt to support more bloated apps, javascript frameworks and botnet phoning home and more GPU for 8K on a 5" screen

Yes, but there are some forms of Lithium batteries that don’t use Cobalt. The non-Cobalt ones, generally store less energy, but last longer.

So, you don't know what a solid state battery is?

>Lithium Reserves

Oh man good joke my dude

>known reserves are 1000x greater than yearly consumption

Yeah, there's essentially infinite lithium out there.

I heard many years ago that Afghanistan was the Saudi Arabia of Lithium. People wonder why there's still Anglosphere troops there.

You are forgetting about the newest Lithium batteries which are entirely solid state and use Iron based cathodes.

The ones commercially available now can be punctured and cut up without exploding like conventional Li based batteries.

Its not Lithium but some other useful element (boron?), the problem is that its so mountainous there that extracting it is far too costly even without the Taliban.

Lithium is extractable directly from sea water.
