Potassium-ion Batteries - Game Changer?

[Z80 Lasers]

I just came across this article. It's about time there's an advancement in battery tech. Lithium is good and all but it pretty much only benefits China in the grand scheme of things.

World’s first 18650 Potassium-ion battery debuts, can replace lithium cells

Lithium batteries, then sodium batteries, it was only a matter of time until potassium hit the table. I wonder how it stacks up against the other cell chemistries in terms of the availability of supporting materials necessary to make it into a battery.

Can't wait until we get all the way up to rubidium and cesium batteries. At this rate won't be too long.

Those will be......energetic!

Yeah this is awesome, it will be nice to move away from lithium and the slave labor to mine it. Cobalt too hopefully someday.

How about some nuclear batteries?

US firms plan nuclear battery with 50-year lifespan to counter China

The nuclear battery will have several key features which will make it safe and desirable for consumers, according to the company.

I have to laugh when I read about the prospects of using one of these to power a cell phone. Yes, they last a long time, but the output is dismal. Get back to me when someone makes one that can put out 1 watt. Presently they have outputs in the 100s of microwatts.

Given how disposable tech is these days, I'm not sure I want electronics to have nuclear material in them
If we put nuclear batteries in things, it will only be a matter of time before some seagull eats enough of them to go critical and level a small beach.
