Lithium-ion batteries are currently the preferred technology to power electric vehicles, but they're too expensive for long-duration storage

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.

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