Fast-Charging Cells Get a Liquid Spray Shield
KIMM researchers used a dielectric spray inside a battery pack to suppress heat buildup and reduce thermal-runaway risk during fast charging.
Summary
KIMM researchers used a dielectric spray inside a battery pack to suppress heat buildup and reduce thermal-runaway risk during fast charging.
A Korea Institute of Machinery and Materials team developed a spray-based immersion cooling system that directs dielectric liquid toward lithium-ion battery cells. The reported tests focus on carrying heat away during high-rate charging and limiting the conditions that can propagate thermal runaway. Spray delivery may use less cooling fluid than flooding an entire pack while still targeting hot regions. The work is a research prototype and does not establish field reliability or certification for a commercial vehicle pack.
