摘要
Abstract
Multi walled carbon nanotubes (MWCNT) and vapor grown carbon fibers (VGCF),activated carbon (AC) were used as the carrier of sulfur.S/C cathode material for lithium sulfur battery prepared by high temperature heat treatment.The structure and electrochemical properties of the materials were analyzed by XRD,SEM,thermogravimetric analysis,galvanostatic charge discharge and cyclic voltammetry.The study found that the discharge of lithium sulfur battery capacity and cycling performance is greatly affected by the carbon material,the electrochemical performance of SNGCF composites is better.When the charge discharge current in 1.5-3.0 V to 0.1 C,the specific capacity of first and 100th discharge cycles was 1 205.62 mAh/g,613.18 mAh/g.关键词
