The Effect of Electrochemical Performance and Safety by Surface Modification of Anode Materials for Lithium Secondary Battery

This paper aims to report the effect of surface treatment on graphite and its effect on the improvement of and . The structure and property of surface treatment on graphite were determined by scanning electron microscopy, transmission electron microscopy and electrochemical property and safety were determined by charge/discharge cycler, accelerating rate calorimeter. The composite with different metallic oxide exhibited the first efficiency of 82.5% and specific capacity of 350 mAh/g. Although the composite showed same efficiency and specific capacity at first cycle, surface treatment on graphite by exhibited a higher charge/discharge rate, cycle life and thermal stability.
