Beijing, April 09 (QNA) – Chinese scientists from the Institute of Physics of the Chinese Academy of Sciences have developed a polymerizable non-flammable electrolyte (PNE) with self-protective capabilities, fundamentally addressing the core safety bottleneck of new energy batteries and accelerating the commercialization of sodium-ion batteries.
Notably, when the battery temperature abnormally rises above 150 degrees Celsius, the PNE automatically transitions from a liquid to a solid state, forming a dense barrier. This acts like a ‘smart firewall’ inside the battery, completely blocking the propagation path of thermal runaway.
Importantly, this breakthrough in safety does not compromise electrochemical performance. According to the institute, the battery offers a wide temperature adaptability ranging from minus 40 degrees Celsius to 60 degrees Celsius, along with high-voltage resistance exceeding 4.3 volts, achieving both high safety and high energy density.
