Prussian blue, the pigment developed by a Berlin color maker in the early 18th century, is a key component in batteries made with sodium rather than lithium, which are intended for industries other than electric vehicles.

This Liquid Metal Battery may just revolutionise energy storage

Under development since 2017, this liquid metal battery (LMB) is about to be let loose on the globe. Consisting of 3 liquid layers; 2 of molten metals and a middle layer of molten salts. The system is self-heating and insulated, but contains no combustible materials - so they can't burn. And they retain all of their charge capacity for at least 5000 cycles (think decades, not years). Modular, safer and cheaper than lithium-ion batteries. https://ambri.com/technology/
