Smaller, faster-charging batteries are presented as a way to make electric vehicles more affordable and sustainable, cut EV costs, lower demand for critical minerals, and provide a gas-station-type experience. The talk addresses pre-warming requirements in cold conditions and safety challenges in hot environments. Chao-Yang Wang argues that fast charging is fundamentally a heating problem rather than a chemistry problem and introduces asymmetric temperature modulation for 10-minute charging of lithium-ion batteries across a wide temperature range while maintaining cycle life. The approach points to a battery-design and thermal-management paradigm without trading off fast charging, safety, lifetime, and cost. Speaker: Chao-Yang Wang, executive director of UL's Electrochemical Safety Research Institute and emeritus professor at Pennsylvania State University.
