Comparing thermal runaway behavior of sodium-ion, lithium-ion batteries

Scientists in Germany have analyzed the thermal runaway behavior of sodium-ion batteries and lithium-ion batteries inside a 10-L reaction vessel. They have thermally abused 30 samples, each under a different state of charge level, and have found that both types suffered from runaway when the charge is at least 50%. Researchers from Germany's Otto von Guericke University Magdeburg have analyzed and compared the thermal runaway characteristics in sodium-ion batteries (SIBs) and lithium-ion batteries (LIBs) with layered oxide cathodes. Thermal runaway is a chain reaction that can occur in batteries ...
