Abstract
At present, graphite is widely used asa negative electrode material for lithium ion battery. Itcannot be able to meet the development demand of lithium ion battery because of its low theoretical specific capacity (372 mAh·g-1). Itis found that SnO2as a negative electrode materialoflithium ion can be a good reversible reaction, and its reversible capacity is much higher thanthat ofthe graphite anode. But in the charge and discharge processparticle pulverizationwill occur in theSnO2leadingto electrode volume expansion,cracking,andthus affecting the lithium battery cycle performance. The addition of graphene to SnO2can alleviate the volume expansion of SnO2during the operation. In addition, the specific surface area and good conductivity of graphene make the graphene/SnO2material have high reversible capacity and better cycle stability. This paper reviews several different methods for the preparation of graphene/SnO2composites,whichexhibit good electrochemical performance when applied to the anode materials of lithium ion batteries.关键词
