Development of lithium ion batteries (LIBs) with higher capacity has been booming worldwide, as growing concerns about environmental issues and increasing petroleum costs. The demands for the LIBs include high energy and power densities, and better cyclic stability in order to meet a wide range of applications, such as portable devices and electric vehicles. Silicon has recently been explored as a promising anode material due to its low discharge potential (<0.4 V) and high specific capacity (4200 mAh g-1). The capacity of silicon potentially exceeds more than 10 times of the conventional graphite anode (372 mAh g-1). However, the silicon anode experiences huge volume …
