What are Solid-State Batteries?
Traditional lithium-ion batteries, the standard for EVs, rely on a liquid electrolyte to facilitate energy transfer between the anode and cathode. However, this liquid component poses significant risks, including the potential for thermal runaway and explosion. Solid-state batteries, on the other hand, replace this liquid with a solid material, such as a ceramic or glass electrolyte. This design change eliminates the risk of liquid electrolyte-related issues, while also boosting energy density, power, and overall performance.
