What solid-state changes
The battery safety ceiling is rising. Gotion's 'Jinshi' all-solid-state cell reaches 400 Wh/kg and passes harsh tests—when penetrated, temperature stays in the safe range with just 0.01% mass loss, far below the 0.5% national limit; a 2 GWh line is under construction and the world's first 10,000-ton high-purity lithium-sulfide line completes in 2027. Anhui has an industry action plan and Qingdao a three-year power-storage plan, covering material, cell and recycling.
A source-side safety gain
For charging safety, safer cells mean 'source-side relief'. Solid-state batteries cut thermal-runaway risk and improve mechanical/thermal stability versus liquid Li-ion, lowering the odds a battery itself triggers an incident during charging, parking or crash. This joins the 'no fire/no blast' vehicle standard (GB 38031-2025) and station fire codes to move safety from 'extinguish after' to 'intrinsic material safety'.
Yantai's forward watch
For Yantai owners and communities, battery progress is a long-term win. Dongdian Huichong's compliant charging also watches intrinsic-battery-safety trends, linking platform monitoring and auto cut-off with vehicle/battery state so every charge serves today's cars and keeps an interface for tomorrow's safer cells.
