Solid-state batteries are a type of battery technology where the electrolyte is a solid instead of a liquid. This enables the use of a higher voltage than is possible with liquid electrolytes, and can also improve safety and thermal stability. The solid electrolyte can also be a polymer, ceramic, or glass.
Some of the emerging trends in solid-state batteries include the use of inorganic electrolytes, the use of solid-state electrolytes, and the use of nanomaterials for electrode materials.
