LiFePO4/Cl石墨锂离子电池的高温循环性能
High temperature cycle performance of LiFePO4/Clgraphite Li-ion battery
摘要
Abstract
High temperature( 60 ℃) 1 C cycle performance of aqueous and non-aqueous lithium iron phosphate( LiFePO4 )/C I graphite system Li-ion batteries was studied by transmission electron microscopy(TEM) .electrochemical impedance spectroscopy (EIS) and 1CP-OES. Compared with symmetric battery using non-aqueous electrode, the symmetric battery using aqueous electrode had similar real part and smaller diffusion coefficient. The results of EIS and monitoring of battery showed that the anode was stable,the polarization of aqueous cathode enhanced gradually. With the increasing of cycle number, the Fe3+ dissolving content increased linearly. When 1 C cycled under high temperature, two kinds of cathode showed the same Fe3+ dissolving contents under the same capacity retention. The polarization of aqueous LiFePO4/C enhanced,led to the faster cycle fading of battery.关键词
