摘要
Silicon monoxide (SiO) is suggested as anode for LIBs with excellent theoretical capacity. Unfortunately, the low electrical conductivity and volume expansion limit its practical application. The preparation of SiO@C composites can effectively solve these problems. SiO@C composite materials are constructed with phenolic resin pyrolysis method. Experimental data indicate that SiO@C-20 with carbon content of 20 wt% possesses a high discharge capacity and superior initial coulombic efficiency (74.81 %) compared to others. The superior performance can be attributed mainly to carbon ratio with adjusting phenolic resin.
