High-performance SiO/C/G Composite Anode for Lithium Ion Batteries
Source abstract
Abstract
以一氧化硅、蔗糖及天然石墨为原料, 通过高能球磨和热解工艺制备了电化学性能优异的SiO/C/G复合负极材料。采用X射线衍射仪(XRD)和扫描电子显微镜(SEM)对复合材料的物相和形貌进行了表征。所制备的复合材料中, 纳米SiO颗粒(＜50 nm＝被无定形碳粘结并均匀分散在石墨鳞片上。电化学性能测试表明, 该复合材料100次循环后, 可逆容量高达1108.9 mAh/g, 容量保持率为103.8%。优异的电化学性能主要归因于纳米SiO颗粒在无定形碳基体中的均匀分布、无定形碳基体的缓冲作用和石墨相对复合材料导电性能的改善。
