The draft for comments on “Solid-State Batteries for Electric Vehicles Part 1: Terms and Classification” divides batteries into liquid batteries, hybrid solid-liquid batteries, and solid-state batteries according to the different methods of ion transfer within the battery cell. The semi-solid-state batteries commonly mentioned in the industry were not included. However, this is consistent with the information previously revealed by the China Automotive Technology Research Center. There is no longer a term for “semi-solid state batteries” in terms and categories. Some industry sources say that for a long time, the “solid state battery” concept has been widely used in the market, but the definition is vague and standards are missing, leading to mixed terms such as “semi-solid” and “quasi-solid state,” and there is even chaos where some companies claim “all solid state” by mixing a small amount of solid electrolyte. The release of the National Standard Consultation Draft is a systematic correction to this chaotic situation.
