充放电倍率对LiNi0.6Co0.1Mn0.3O2/石墨电池的影响
Effect of charge-discharge rates on LiNi0.6Co0.1Mn0.3O2/graphite batteries
摘要
Abstract
For high-capacity ternary LiNi1-x-yCoxMnyO2/graphite pouch batteries,reverse analysis confirmed that the active material composition of the cathode electrode was LiNi0.6Co0.1Mn0.3O2(NCM613),and the main body material of the anode electrode was graphite.The capacity perform-ance,cycling stability,and polarization differences of the battery under different charge-discharge rates were systematically compared through the charge-discharge test.The results showed that the in-itial discharge capacity of the battery was 32.65 A·h(25℃)at 1/3 C,slightly higher than the nomi-nal capacity.When the rate was increased to 3 C,battery capacities greatly declined.The dQ/dV curves demonstrated that a large rate could cause a shift in the potential of battery redox reactions and weaken the degree of reaction.The batteries were provided with excellent cycling performance but showed significant differences in voltage relaxation effects during charge and discharge intervals at 1/3 C and 3 C.With the help of battery disassembly technologies combined with XRD and SEM analy-ses,it was demonstrated that the charge-discharge processes could slightly increase the interplanar spacing of NCM613 material,and high charge-discharge rate processes were more likely to cause dam-age to the electrodes.关键词
