China Unveils First National Standard for Solid-State Batteries
China has taken a step toward industrializing solid-state battery technology with the release of its first national standard, published by the National Automotive Standardization Technical Committee on December 30. The new standard aims to establish terminology and classifications for these advanced batteries.Key TakeawaysThe draft includes a strict classification system based on ion transfer methods and electrolyte type.To qualify as solid-state, the weight loss rate must not exceed 0.5% under specific testing conditions.A more stringent verification criterion than previous industry guidelines is introduced to ensure quality control.The new standard defines three types of batteries based on ion transfer methods: liquid electrolyte, hybrid solid-liquid, and pure solid-state. This classific...
