Graphene protected silicon alloy-based Li-ion batteries

The proposed research aims to advance energy storage technology by improving the cyclability of silicon-based anodes in lithium-ion batteries. Silicon anodes offer high theoretical capacity but face issues such as volume expansion and capacity fade. The project will explore substituting pure silicon with a silicon-carbon alloy core, hypothesized to enhance cyclability due to its amorphous structure and oxidation resistance. The research involves synthesizing silicon-carbon alloy particles, integrating them into shell/core structures, optimizing electrode casting, and testing electrochemical performance. Successful outcomes could significantly boost the energy density and commercial viability of silicon-based anodes.
