flag Chinese scientists developed solid-state batteries with 1,000 km range, self-repairing interfaces, and enhanced safety.

flag Chinese scientists have made significant strides in solid-state battery technology, enabling electric vehicle ranges exceeding 1,000 kilometers—more than double current limits. flag Key breakthroughs include a self-repairing iodine-ion interface that improves contact between electrolytes and lithium metal electrodes, a flexible polymer electrolyte that survives 20,000 bends and increases energy capacity by 86 percent, and a fluorine-reinforced electrolyte that enhances voltage stability and passes extreme safety tests, including nail penetration and 120°C exposure, without fire or explosion. flag These advances collectively enhance performance, safety, and durability, accelerating the path to commercial use.
