【摘要】 采用软化学法合成钴酸锂（ＬＩｘＣｏＯ２）并对产物进行ＸＲＤ，ＳＥＭ，ＩＲ，ＸＰＳ及ＩＣＰ测试．结果表明，与固相法相比，该法具有烧结温度低（５００℃），烧结时间短（４ｈ）的优点．对用ＬｉＣｏＯ２微粉作正极活性物质组成的Ｌｉ／ＬｉｚＣｏＯ２电池进行电化学测试结果表明，电池充电电压可达 ４．５Ｖ（ｖｓ，Ｌｉ），第一次充电比容量为１４６ｍＡ·ｈ·ｇ－１，循环２５周后的放电比容量为１３５ｍＡ·ｈ·ｇ－１，终止电压３．０Ｖ（ｖｓ，Ｌｉ），容量损失为７．５％．更多还原

【Abstract】 LiCoO2 Powders had been synthesized by soft chemistry method. The products were measured by XRD, SEM, IR, XPS and ICP, the results come to the conclusion that this is a good method with low sintering temperature of 500C and with short sintering the of 4h comparing to the traditional sintering method. The electrochemistry tests using Li/LiCoO2 cell with LiCoO2 as active cathode materials show that the change voltage is 4.4V (vs. Li), the first charge capacity is 146mA. h. g-1,the discharge capacity is 135mA· h· g-and capacity loss is 7. 5% after 25 cycles,cut off voltnge is 3. 0V(vs Li).更多还原
