锂镍锰复合氧化物正极材料的制备与掺杂改性研究
|
摘要
近年来，以嵌锂化合物作为正极材料的锂离子蓄电池由于具有电压高、质量轻、比能量高的优越性能，成为便携式摄像机，个人通讯服务、蜂窝电话、笔记本电脑等移动电子器件的主要能源，其重要性正日益增长。目前，LiCoO2由于容量高，可逆性和倍率性好成为商业化锂离子电池的主要正极材料，但其成本高，Co有毒，人们努力寻找一种可替换材料。LiNiO2和LiMnO2研究最多，虽取得了很多进展，但由于存在各种问题而不能实际应用。固溶体多元体系的合成与性能的研究，已经成为该材料领域的一个重要的研究方向。
本文采用共沉淀法成功地合成了二元Li[NixLi1/3-2x/3Mn2/3-x/3]O2（0 实验结果表明：以氢氧化锂为锂源，压片处理，锂源与共沉淀摩尔比为1.05：1，850-900℃下培烧3小时的LiNi0.5Mn0.5O2样品电化学性能最佳，在2.75-4.40V之间，10mA/g的电流放电可逆容量达150.6mAh/g。
采用最佳合成工艺合成了三元Li[Ni(1-x)/2CoxMn(1-x)/2]O2（0 为进一步提高LiNi0.5Mn0.5O2的电化学性能，引入掺杂离子Al和Ti离子，掺入Al、Ti后对LiNi0.5Mn0.5O2的电化学性能有较大的改善，电化学可逆容量提高10-20mAh/g，充放电效率明显提高。
Recently rechargeable lithium-ion batteries based on the uses of intercalation compounds as cathode materials are becoming increasingly important as the main power sources in portable electronic devices, such as Personal Communication Services(PCSs),cellular phones, camcorders, and notebook PCs, because these batteries have superior properties like high voltage, high energy density and light weight.Currently,LiCoO2 is being used as the cathode material in the majority of commercial lithium-ion batteries with good capacity ,reversibility and rate capability, but suffers from high cost and the relatively toxicity of cobalt.
Much effort has been made to develop possible alternatives as a positive electrode. To this end , LiNiO2 and LiMnO2 have been studied extensively, Although there has been a lot of progress, they still possess various problems for practical applications. synthesis and characterization of solid solution have been an important research field in material science.
In this work, layered Li[NixLi1/3-2x/3Mn2/3-x/3]O2（0 The results got from the experiments show that the sample of LiNi0.5Mn0.5O2 which were sintered for 3h at 850-900℃ from LiOH:M(OH)2=1.05:1,pressing pellets, quenching pattern are best. LiNi0.5Mn0.5O2 exhibited a discharge capacity of 150.6mAh/g in the voltage range of 2.75-4.40V and at a specific current of 10mA/g.
Li[Ni(1-x)/2CoxMn(1-x)/2]O2（0 In order to improve the electrochemical performance of LiNi0.5Mn0.5O2, we introduced Al and Ti ions, The doping of Al and Ti ions improved electrochemical performance greatly, reversible capacity is increase by 10-20 mAh/g, and they displayed a high coulombic efficiency.
