The investigation and developing of lithium - ion batteries have attracted worldwide attention due to their excellent properties such as high cell voltage and specific capacity , and so on . remarking progress has been made on researching carbon anode materials 锂离子电池以电压高、比容量大等优点倍受世人关注,对锂离子电池的碳负极材料的研究已取得较大的进展,但正极材料中因锂钴氧化物价高而使其应用受到限制,开发新型的正极材料已是当务之急。
( 2 ) using the monomer containing the element of nitrogen or silicon , the organic gels doped uniformly by nitrogen or silicon were synthesized and carbonized into nitrogen or silicon - doped carbon xerogels . the carbon xerogels doped by metal elements of cadmium , cerium and zirconium were also prepared by uniformly introducing into cadmium , cerium and zirconium in the synthesis of organic gels precursor . the performance of lithium ion storage and behavior of charge and discharge of these doped carbon anode materials were studied , and the effects of the level of doped elements on the structure of carbon materials , furthermore on the act of storing lithium ions were accompanyingly analysed ( 2 )通过利用含氮、含硅单体合成氮、硅元素均匀掺杂的有机凝胶,以及在前体合成中均匀引入cd 、 ce和zr金属元素的方法,制备了氮、硅及cd 、 ce和zr均匀掺杂的多孔碳阳极材料,考察了这种掺杂碳阳极材料的储锂性能和充放电过程,分析了掺杂元素水平对碳材料结构,从而对其储锂行为的影响,并进一步分析了基于有机凝胶的多孔碳阳极材料的储锂机制。
