摘 要：用包裹沉淀法合成了具有尖晶石结构的 可用作锂离子二次电池正极材料的锂锰氧(LiMn2O4) 化合物．对材料进行了X射线衍射、循环伏安、充放电等测试，实验结果表明，所合成的材料具有标准尖晶石结构和较好的电化学可逆性能，该材料在EC DMC(1∶1)+1 mol/L LiPF6 电解液中表现出较优良的充放电性能，其放电容量达120 mAh/g．
Abstract: The spinel LiMn2O4 used as cathode materials for lithium ion batteries was synthesized by coprecipitation coating process. Testing of X-ray diffraction , cyclic voltammograms and charge-discharge were carried out for LiMn2O4 cathode materials. Results showed that the synthesized materials exhibited standard spinel structure, high reversibility of electrochemistry and excellent properties of charge discharge in EC DMC(1∶1)+1 mol/L LiPF6 electrolyte with discharge capacity 120 mAh/g.
