Chinese Scientists Develop Fireproof Sodium-Ion Battery
Key Takeaways
- 1New sodium-ion battery design features non-flammable electrolyte.
- 2Chemical solidification at 150°C improves safety and performance.
- 3Innovation may reduce dependency on traditional lithium-ion batteries.
Researchers from the Chinese Academy of Sciences have unveiled a sodium-ion battery design featuring a non-flammable polymerizable electrolyte (PNE) that solidifies at internal temperatures exceeding 150°C. This chemical transformation creates a physical barrier, enhancing fire safety by acting as a firewall against ignition during extreme conditions. Published in Nature Energy, the study documents experimental testing demonstrating its resilience, even at temperatures reaching 300°C without catching fire.
