All-Solid-State Battery Safety Myth Shattered? Industry Experts Urge Consumer Rationality
All-solid-state batteries have been widely regarded as the "ultimate solution" for power batteries by both industry and consumers, but their safety profile may be more complex than imagined. At the 2026 China Automotive Forum, FAW Group chief scientist Wang Deping issued a sober warning: once thermal runaway occurs in all-solid-state batteries, the consequences can be extremely severe. Academician Ouyang Minggao of the Chinese Academy of Engineering went further, telling consumers there is no need to wait for all-solid-state batteries. Japan's JISC released JIS C 8905-2 in May 2026, introducing mandatory thermal runaway propagation testing for solid-state batteries, while IEC 63254 entered CDV voting in April. Meanwhile, not a single vehicle claiming to use "solid-state batteries" in the 2026 market is actually "all-solid-state."
