Eh, if lithium runs short then we use battery formulations that use less lithium. Or switch to magnesium or phosphate batteries. Or if we don't want to do as much work, we go to nickel metal hydride or plain old lead acid.
 
Once lithium, nickel and cobalt get scarce enough they will go looking for more. And formulate ways of using less of it. And eventually we'll have a decent battery recycling system in place, so I wouldn't be too concerned.
 
All that is would be optimism. Demand doubles, they use 10% less in a cell, we wind up needing 9x more lithium for 10x the useage. That still means electrics are just a niche.

There will have to be batteries other than lithium. And probably no dominant chemistry unless we can grow it. Any ideas for a corn battery?

Yep. Even today we have Li formulations that use little to no cobalt. Scarcity will drive cost, and that cost will drive research into, and then changes in, battery chemistries.
 
Much like increasingly expensive rare earth element magnets has incentivised the development of switched reluctance motors/generators.

Its the old peak oil trap. People assume that demand will follow trend growth, but rarely assume supply will follow trend growth. There are usually seemingly good reasons for that ("Population is growing, but no new oil is being made!").

However, this fails to take into account innovation and economic drivers. E.g. at $5 a barrel, a huge amount of oil is uneconomical to extract, but at $150 a barrel, a lot more is.

Likewise, seawater extraction might become feasible, or we might start near earth object mining.

I'm not saying we should waste what we have assuming there is guaranteed an alternative, but at the same time, we shouldn't be waiting until an alternative is available to allow what reserves we know we have to be used either. Remember, the first peak oil prediction was made in the 1880s - nearly 140 years ago.
 
I understand that village scale sodium based flow batteries are only a matter of a few years away based on the recent discovery at MIT with metallic matrices. They are aready at 150kwatthours/kg. with really long life span. Lithium isn't the only horse in the race.

Isn't that essentially what the human metabolism system is? Why can't we copy that to power our machines? An elephant is a gigantic machine, and it runs on hay ...

In general, it can be a bad idea to give people the choice between feeding the hungry and powering their machines.

Flow batteries, of various chemistrys, have been commercially available and in use for several years.
They have not made much impact on the storage market, and have their own issues to resolve.
150 kWh/kg is a typo im sure ! :lol:

Amusing choice of phraseology. :lol:
