摘　　要：通过对AA型中间相炭微球(MCMB)- LiCoO2锂离子蓄电池及以MCMB为负极、LiCoO2为正极、金属锂为参比电极的AA型三电极锂离子蓄电池的性能测试及正负极对锂参比电极的电位测试,并结合双电极模拟电池的交流阻抗实验,研究了MCMB- LiCoO2锂离子蓄电池的性能及其容量衰减的原因。结果表明:在室温条件下,电池的1 C放电容量达600 mAh,并具有较好的循环性能和倍率特性。电池的倍率特性和容量衰减主要受正极控制。The AA size LiCoO2-MCMB lithium-ion batteries and AA size three-electrode lithium-ion batteries, by using LiCoO2 as cathode electrode, MCMB as anode electrode and lithium metal as reference electrode, were assembled. the performances and capacity fade of LiCoO2-MCMB lithium-ion batteries were investigated by combining performance measurements, the potential measurements of cathode and anode vs. lithium reference electrode with two-electrode AC impedance measurements. The results show that the batteries discharge capacity is 600 mAh and has excellent cycling stability and rate capability. And the rate capability and capacity fade of the lithium-ion batteries are limited by the LiCoO2 cathode electrode at room temperature.
