The "How" Behind China's 1000-Kilometer Battery Revolution

China's 1000km solid-state battery is more than a headline; it's a collection of specific breakthroughs. Researchers at Tsinghua University have created a "fluorine reinforcement" shield, allowing the battery to withstand 120°C and nail penetration tests, ensuring safety at high voltage. Concurrently, other teams have developed a "smart glue" of iodine ions to create a self-repairing, highly efficient interface, and a polymer skeleton that allows the battery to be bent over 20,000 times. This combination of safety, flexibility, and performance explains the credible threat to the gasoline engine.
