Abstract

As demand in the electric vehicle market increases, the development of high capacity, high energy density lithium-ion batteries (LIBs) is required. Silicon has a extremely high theoretical capacity of 4200 mAh/g, but low cycle life and structural instability due to high volume expansion during charging and discharging are critical issue to solve. A reduced silicon oxide has also a high theoretical capacity of 2500 mAh/g and recently studied extensively for its low-cost, superior cycle life, and structural stability.
