  Abstract

Silicon is promising anode materials for lithium-ion batteries owing to its brilliant capacity (3,579 mAh g–1) and low operating voltage (< 0.2 V), however, the drastic volume expansion more than 300% caused inferior stability and drastic capacity fading. Herein, Silicon oxycarbide (SiOC) has been coated on the porous silicon (PSi) surface using silicone oil and sintering process to diminish volume expansion and enhance cycle stability of anode. SiOC shows the improved mechanical strength owing to ceramic properties, which accommodate the volume expansion during discharging and charging. Furthermore, the PSi and SiOC composite showed 1,587 mAh g–1 at 40 cycles
