摘　　要：为了研制在电性能、安全性和成本价格等三方面均能较好地满足电动汽车需求的锂离子电池,选择了在氧化钴锂中掺杂氧化镍锰钴锂三元材料的方法,研制了新的50Ah动力型锂离子电池。通过对研制电池进行电性能和安全性试验,各项性能均满足电动汽车的技术要求,加上氧化镍锰钴锂三元材料的价格仅为氧化钴锂的50%左右,所以掺杂氧化镍锰钴锂三元材料是解决电动汽车对动力型锂离子电池严格需求的理想途径之一。In order to get a good balance on electric performance, safety property and low cost of lithium ion battery for electric vehicles, a new design on 50 Ah power Li-ion battery with mixed material of LiNi1/3Co1/3Mn1/3O2 and LiCoO2 was given. The test result on electric performance and safety property satisfied the technical requirement of the EVs. Moreover, in the aspect of price, tripe-element material is just half of the price of LiCoO2. Therefore, using LiNi1/3Co1/3Mn1/3O2 doping cathode material shall be one of the ideal solutions for power Li-ion battery to meet the strict requirement of EVs power packs.
