Lithium-ion batteries, fuel cells and many other devices depend on the high mobility of ions in order to work properly.

Solid-state batteries, currently used in small electronic devices like smart watches, can be safer and more powerful than lithium-ion cells.

QuantumScape has announced impressive performance figures for what may be the first commercially viable lithium metal solid state battery.

Researchers are working to replace the liquids commonly used in today’s lithium ion batteries with solid materials.
