1. 毕业设计的内容

锂离子电池由于具有高的能量密度，长的循环寿命，已广泛应用于各种便携电子设备。未来，锂电池有望用于电动车等动力电池领域。电池的性能取决于电池材料。目前锂电池负极材料发展迅速，正极材料成为锂电池大范围应用的瓶颈。开发高容量锂电池正极材料迫在眉睫。li₂fesio₄由于存在2个锂脱嵌的可能性，理论容量高达330 mah g^-1,近年来人们对其的研发兴趣日益剧增。但是该材料离子和电子电导率极低，需要与碳复合进行改性。

本课题拟采用表面活性剂辅助的溶胶-凝胶法制备碳前躯体-甲阶酚醛树脂溶胶，然后往此溶胶中加入li₂fesio₄的前躯体，惰性气氛下煅烧后获得li₂fesio₄@c复合物，对获得的复合物进行微结构和电化学储锂性能研究。
