On April 6, 2026, the team led by Hu Yongsheng published an important achievement in Nature Energy, successfully developing a self-protection polymerizable non combustible electrolyte that completely blocks thermal runaway in ampere hour sodium ion batteries for the first time in the world.

Intelligent protection blocks thermal runaway

The team abandons traditional flame retardant ideas and builds a triple safety protection system. When the battery temperature exceeds 150 ℃, the electrolyte will automatically solidify to form an isolation barrier, preventing the spread of thermal runaway from the source.

Excellent performance is conducive to industrialization

This battery can operate stably in an environment ranging from -40 ℃ to 60 ℃, and has high voltage resistance. The raw materials used are mature and readily available, making it highly competitive in industrialization. This achievement has revolutionized the concept of battery safety and will be applied to related sodium ion battery products in the future, laying a solid foundation for the large-scale application of new energy vehicles, energy storage, and other fields.Editor/Gong Ziwei
