Asahi Kasei Develops Pre-Lithiation Technology for Silicon-Rich Li-Ion Batteries

Asahi Kasei, a diversified global company, has developed a novel pre-doping technology for high-voltage lithium-ion batteries (LIBs) with silicon-based anodes. This technology enables lithium carbonate to serve as an additional lithium source at lower voltages, reducing the permanent capacity loss that typically occurs in silicon-rich cells during the first charge–discharge cycle. Going forward,…
