Silicon, which is expected to be the next-generation active material for lithium-ion secondary batteries, has high energy density and is suitable for high capacity. However, it has a drawback that the filling and releasing of lithium ions causes rapid volume expansion and contraction, resulting in a rapid decrease in charge-discharge capacity. Therefore, we investigate the process of impregnating silicon substrate with lithium (ions) and the synthesis of silicon-lithium compounds as active materials in order to mitigate the volume change of Si. In order to impregnate silicon with lithium ions efficiently, we have decided to try an intercalation method of lithium ions into silicon substrates using an inductively coupled plasma (ICP) system.
