Entropy Production: Sodium-ion Batteries
My only hope is that they can figure out a reliable method of DIRECTLY substituting one of lithiums cheaper relatives like sodium or potassium, both alkalie metals they should be interchangable with some side effects, namely different capacities.
WebElements Periodic Table of the Elements
Note I am NOT talking about existing super hot sodium batteries, sodium should be able to used exactly as lithium.
Lets hope someone figures out a good way of reducing it and making room temperature sodium or potassium ion batteries, not to mention they could potentially have more capacity.
Remember this?
Super iron battery - Wikipedia, the free encyclopedia
Potassium & sodium are both stronger materials for batteries if they can be constructed safely.
I still have hope someone will pick up the ball.
Potassium and sodium are both abundant and cheaper than dirt.

I read somewhere that Bolivia has quite a bit of lithium (I don't know where I read that). The only source (sales) I have locally is about $800. for a 36V lithium battery, and means cutting a panel to install it that covers the old lead-acid 36V. I sure wish new technology would hurry up - I am waiting for prices to fall like a rock (like calculators, TVs, oil)

Lithium battery prices have fallen like a rock but there are still no inexpensive methods for Battery management on the market that actually work. Also the price is still high but not as high. $20k down to about $4-5K for me if I were to convert my c-car

(this isn't the 1st to go under $0.50 a wthr)

What about li-poly technology? Can can these type of batteries be constructed big enough for ev's. I know the one's used for R/C are relatively inexpensive.

Since this seems thread now seems to be a repository for obscure battery technology, have some Zinc-Air batteries.

Isn't that the same as the $.35 ones I linked to? LIFEPO4 is much more stable and is the best lithium battery available for an EV at the moment, that isn't to say the the sulphur or magnesium varieties might not overcome it with time.
