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

Nature Communications, 2023
The mass adoption of electric vehicles is hindered by the inadequate extreme fast charging (XFC) performance (i.e., less than 15 min charging time to reach 80% state of charge) of commercial high-specific-energy (i.e., >200 Wh/kg) lithium-ion batteries ...
