Asahi Kasei develops lithium carbonate pre-doping technology to boost energy density in silicon-anode batteries

Asahi Kasei Corp. (Tokyo, Japan), 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…
