Abstract
The effects of adding carbon nanotubes (CNTs) as conductive agent on the properties of lithium ion batteries using LiFePO4,LiNi0.5Co0.2Mn0.3O2 and LiMn0.8Fe0.2PO4 as composite cathode materials were investigated.The results indicate that the lithium ion batteries using LiFePO4,LiNi0.5Co0.2Mn0.3O2 and LiMn0.8Fe0.2PO4 as composite cathode materials show excellent safety performance.The discharge specific capacity,low-temperature performance and rate capability can be improved by adding CNTs as conductive agent in the cathode electrode.The batteries with the cathode adding CNTs as conductive agent exhibit excellent cycling stability,the capacity retention is 95.34％ after 500 cycles and 90.09％ after 1 000 cycles at 3 C.关键词
