Tomorrow''s super battery for electric cars is made of rock

A lithium-ion battery works by moving lithium ions through an electrolyte liquid from the cathode (made of a mix of metals including lithium and cobalt) to the anode (made from graphite). Lithium-ion and potassium-ion batteries work in the same way. Here, lithium has simply been replaced with potassium.
