Indian researchers innovate lithium-ion battery safety
A team at Shiv Nadar Institution of Eminence has come up with a smart new electrolyte that can actually shut down lithium-ion batteries before they get dangerously hot.
This tech could make phones, laptops, and electric vehicles much safer by stopping fires before they start.
The electrolyte uses a clever chemical reaction
The electrolyte uses a clever chemical reaction—thanks to Diels-Alder chemistry—that kicks in above 100°C.
Normally, it acts like any regular battery fluid, but if things heat up too much, it forms polymers that block the flow of lithium ions and seal off battery pores.
A shift from passive to active safety for batteries
Unlike standard separators that only fail after reaching higher temperatures (about 160°C), this new approach steps in early to prevent overheating disasters.
It marks a shift from passive to active safety for batteries and puts India on the map for cutting-edge energy research.
