微细孔结构的锂离子电池电极材料及其制备方法
摘要：
本发明公开了一种具有微细孔结构的锂离子电池电极材料及其制备方法。以碳纳米管等纳米碳材料为孔道模板，通过固相法或者溶胶－凝胶法制备内部均匀分散着模板材料的锂离子电池电极材料，再通过氧化反应将模板材料去除，获得具有微细孔结构的电极材料。该微细孔结构电极材料因与电解液接触面积大、锂离子在电极材料中迁移路径短而适合高倍率充放电。该微细孔结构电极材料可以是LiCoO2、LiNiO2、Li(Ni1/3Co1/3Mn1/3)O2、LiMn2O4、LiFePO4等正极材料或者是Li4Ti5O12、SnO2等负极材料。
摘要（英）：

The invention discloses a lithium ion cell electrode material with a micropore structure and a method for preparing the same. A carbon nanometer tube and other nanometer carbon materials are used as pore canal template; the lithium ion cell electrode material of which the inside is evenly dispersed with the template material is prepared by a solid phase method or a sol-gel method; and the template material is removed through oxidation reaction, thereby obtaining the electrode material with the micropore structure. As the electrode material with the micropore structure has large contact area with electrolyte and lithium ion has short migration path in the electrode material, the electrode material is suitable for high-rate charging and discharging. The electrode material with the micropore structure can be LiCoO2, LiNiO2, Li (Ni1/3Co1/3Mn1/3) O2, LiMn2O4, LiFePO4 and other positive electrodes or Li4Ti5O12, SnO2 and other negative materials.
