Extreme fast charging of commercial Li-ion batteries via combined thermal switching and self-heating approaches

Y. Zeng, B. Zhang, et al.

This groundbreaking research conducted by Yuqiang Zeng and colleagues at Lawrence Berkeley National Laboratory unveils a novel approach to enhance extreme fast charging (XFC) in lithium-ion batteries. By actively managing self-generated heat, the study demonstrates a transformative method to achieve <15 min charging and 1 h discharging, meeting stringent US Department of Energy targets—all without structural modifications to the batteries.
