This document describes a new type of battery that is safer and longer lasting than current lithium-ion batteries. The battery replaces the flammable liquid electrolyte with a solid electrolyte made of ceramics and polymers. It maintains the same energy density as lithium-ion batteries, but the solid electrolyte prevents short circuits and allows faster charging. The solid-state battery could revolutionize the electric vehicle and consumer electronics industries by reducing safety concerns and giving products longer battery life.
