【摘要】 锂离子电池负极材料是一种具有宿主结构的化合物,能够在较大的组成范围内允许锂离子可逆地脱出和嵌入。作为锂离子电池负极材料,Li4Ti5O12循环容量非常稳定,但导电性较差,且电压相对于锂为1．5V,应考虑对其进行掺杂改性。掺杂导电物可改善高Li+及电子的传导率,通常所采用的是碳。碳掺杂后产物未见明显板结,易研磨,在合成过程中掺入碳后,材料电化学性能有显著提高。
【Abstract】 The lithiumion battery anode material is a kind of compound who has the host structure, allow the lithium ion emerging and insetting in biggerly constitute scop.As an anode material of lithium-ion battery, Li4Ti5O12 ’s circulation capacity is very stable, but its electrical conductivity is low, and electric voltage is 1.5V (vs Li), The research on enhancing its capacity should be taken on. Blend to conduct electricity ameliorable and high conduction rate of Li+ and electronics usually is carbon which to adopt. After carbon adoption the rigidity and the conductivity was obviously changed.
