Silicon is widely recognized as one of thepromising anode materials for high energy density of lithium-ion batteries(LIBs). Silicon is a representative anode material for next-generation due toits advantages such as high theoretical capacity and low electrochemicalreduction potential. However, their huge volume changes during the charge/dischargeprocess and low electrical conductivity can be critical problems to be utilizedas the anode material. In this study, we solve the large volume expansion ofsilicon anodes by using the carbon-coating method from the reusable phenolicresin for high performance in LIBs. The surrounding carbon layers on siliconsurface were well made from phenolic resins. Consequently, the electrochemical performanceof carbon-coated silicon anode accomplished high specific capacity andexcellent capacity retention. This work provides the strategy for replacingother silicon-based anodes for energy storage systems. |
