Solid-State Battery Industry Standards

What Are Solid-State Batteries?

Solid-state batteries are a type of energy storage device that replaces the liquid or gel electrolyte found in traditional lithium-ion batteries with a solid electrolyte. This innovation addresses several limitations of conventional batteries, such as safety risks, energy density, and longevity. Solid-state batteries are composed of three primary components: the solid electrolyte, the anode, and the cathode. The solid electrolyte facilitates ion transport between the anode and cathode, enabling the battery to store and release energy.
