采用ＸＲＤ和ＡＡＲ分析技术，研究了ＬｉＣｏＯ＿２电极在充电过程、放电过程以及充放电循环过程中晶胞参数变化规律．发现在这些过程中，ＬｉＣｏＯ＿２晶胞出现规律性的收缩和膨胀；过充电时产物Ｃｏ＿３Ｏ＿４，导致Ｌｉ＿ｘＣｏＯ＿２晶格的破坏；循环过程中晶胞参数Ｃ＿０值的变化与充电过程相似．各种状态下００６峰的变化最敏感．于７００℃预热２０ｈ后再高温合成的Ｌｉ＿ｘＣｏＯ＿２，其００６峰得到明显的加强，其循环伏安曲线可逆性很好，第１０００次几乎与第一次相同，实验电池１００％ＤＯＤ循环大于２７０次，ＡＡ型锂蓄电池或ＡＡ型锂离子蓄电地实验在进行中．
XRD and AAR analysis techniques were used to study the variation of unit cell parameters during charge, discharge and charge-discharge cycles in LiCoO_2 electrode. It was found that during these processes, the regular shrinkage and expansion of LiCoO 2 unit cells occurred. The product Co_3O_4 overcharged resulted in the destruction of the Li_xCoO_2 lattice. The change of the unit cell C_0 value during charging was similar to that of the charge process. 006 peak changes in various states most sensitive. At 700 ℃ for 20h, Li_xCoO_2 was synthesized at high temperature. The 006 peak of Li_xCoO_2 was significantly enhanced. The cyclic voltammogram showed good reversibility. The 1000th cycle was almost the same as that of the first cycle. The 100% DOD cycle was more than 270 times , AA-type lithium batteries or AA-type lithium-ion power storage in the experiment.
