An Overview on Thermal Safety Issues of Lithium-ion Batteries for Electric Vehicle Application

Lithium-ion batteries (LIBs) are being intensively studied and universally used as power sources for electric vehicle applications. Despite the staggering growth in sales of LIBs worldwide, thermal safety issues still turn out to be the most intolerable pain point, and remain the focus of research f...
