摘要:
为解决二硫化钴作为锂离子电池负极材料倍率性能差、循环寿命短的问题，以钴甘油酸酯球为模板，通过刻蚀络合反应、硫化反应和聚合反应制备了具有蛋黄多层异质壳结构的二硫化钴@二硫化钴/硫化锌/聚多巴胺微球。采用扫描电子显微镜、透射电子显微镜、X射线衍射仪、X射线光电子能谱仪、拉曼光谱仪、电池性能测试仪和电化学工作站对微球的形貌、结构和储锂性能进行测试与表征。结果表明：以二硫化钴@二硫化钴/硫化锌/聚多巴胺微球用作锂离子电池负极材料，在电流密度为1.0 A/g的条件下循环600次后，放电容量保持在921 mAh/g，在10.0 A/g的高倍率下放电容量为184 mAh/g，这证明微球具有稳定的循环性能和优异的倍率能力。研究表明，蛋黄多层异质壳结构为二硫化钴在锂离子电池负极材料的应用提供了新的复合设计思路。
