| 英文摘要 | Cycle-life tests of commercial 22650-type olivine-type lithium iron phosphate (LiFePO4)/graphite lithium-ion batteries were performed at room and elevatedtemperatures. A number of non-destructive electrochemical techniques, i.e., capacity recovery using a small current density, electrochemical impedance spectroscopy, and differential voltage and differential capacity analyses, were performed to deduce the degradation mechanism of these batteries. To further characterize their internal materials, we disassembled the batteries, and material analyses were performed. All results indicated that loss in active lithium was the main reason for battery aging, and the cells showed diverse recession of active materials at different temperatures. In addition, high discharge rate and growing impedance lead to a capacity fall down at 25 A degrees C at approximately 300-500 cycles. |
