Silicon electrodes degradation at cycling

On basis of analysis of literature data as well as of own experimental results we suggest some regularity for degradation of silicon electrodes upon cycling. It was shown that an electrode capacity Q at n-th cycle can be calculated from equation Q = Q0 exp(kn+βn2/2), where Q0 is initial capacity value, k и β are empiric constants.
