成果介绍

本发明公开一种锂离子电池负极材料及其制备方法，其中，所述制备方法包括：将预先制备的多孔氮掺杂碳纳米纤维膜加入到含有可溶性铜盐和可溶性钴盐的混合溶液中，通过溶剂热法使铜离子和钴离子沉积到多孔氮掺杂碳纤维膜内部；取出所述多孔氮掺杂碳纤维膜并依次在惰性气氛下和空气气氛下分别对所述多孔氮掺杂碳纤维膜进行第一次煅烧处理和第二次煅烧处理，在所述多孔氮掺杂碳纳米纤维膜中生成铜‑钴氧化物异质结构，制得所述锂离子电池负极材料。本发明制备的锂离子电池负极材料不仅可以有效地在电极之间快速传输离子和电子，且铜氧缺陷的引入更是极大地提高了材料的导电性，而且不同的氧化物之间可互为缓冲，用以缓解循环过程中的体积效应。
