Asahi Kasei Pre-Doping Tech Cuts First-Cycle Loss in Silicon-Rich Battery Cells

Asahi Kasei has developed a lithium pre-doping technology that compensates for irreversible capacity loss in silicon-based anodes, boosting energy density by 10% in tests. The method uses inexpensive lithium carbonate and existing manufacturing lines, targeting high-energy EV batteries.
