Chinese researchers develop self-protecting electrolyte that prevents thermal runaway in sodium-ion batteries ⭐️ 9.0/10

On April 6, a team led by Hu Yongsheng at the Chinese Academy of Sciences’ Institute of Physics published a breakthrough in Nature Energy, developing a polymerizable non-flammable electrolyte (PNE) that completely prevents thermal runaway in ampere-hour-level sodium-ion batteries. This electrolyte automatically solidifies into a dense barrier when battery temperature exceeds 150°C, creating an ‘intelligent firewall’ that blocks heat propagation without compromising battery performance. This breakthrough addresses the critical safety challenge of thermal runaway that has hindered large-scale commercialization of sodium-ion batteries for electric vehicles and grid energy storage. By providing a comprehensive safety protection system that doesn’t sacrifice performance, it could accelerate the adoption of sodium-ion batteries as a more affordable and safer alternative to lithium-ion batteries in multiple applications. The PNE electrolyte forms a protective cross-linked barrier through thermally triggered polymerization when temperatures exceed 150°C, creating physical isolation between electrodes. This breakthrough was achieved in ampere-hour-level cylindrical cells, representing practical battery sizes rather than just laboratory-scale demonstrations, and the electrolyte maintains excellent wide-temperature performance and high-voltage stability.
