This was literally in the post under this one: https://www.notebookcheck.net/Lithium-metal-battery-with-over-500-Wh-kg-developed.862073.0.html
I just want reliable long-term storage. Even if it's a trickle of power coming out, I want it to be reliable and large, so that I can just throw energy at it when I don't need it and can rely on it when I do.
That's energy density, not power density. https://www.energyeducation.ca/encyclopedia/Energy_density_vs_power_density
If a loaf sized battery could hold 100 miles, I'd put 100 of them in a car and only recharge them every 10000 miles.
I'd be okay with how long it would take to charge.
