摘要

The use of silicon as an anode in lithium batteries has long held the attention of the research community because of the high capacity of this material when compared to graphite anodes (3579 mAh/g for Si vs. 372 mAh/g for graphite). However, the material experiences a large volume change (280%) during lithiation/delithiation, which in turn leads to rapid capacity fade.
