摘　　要：介绍了一种CoOOH的新包覆工艺,对在球形石墨表面进行包覆CoOOH的电化学性质进行了测试和研究。研究结果表明:该方法得到的CoOOH,其中钴的价态更高,具有更好的导电性能。使用该工艺包覆的球形Ni(OH)2作正极活性物质进行的测试表明:此种工艺在提高利用率、减少电池化成步骤等方面有应用价值。The cobalt oxyhydroxide had been chemically coated on the surface of the graphite powder and the electrochemical property of CoOOH-coated graphite had been evaluated. The chemically synthesized CoOOH showed a high conductivity because of high oxidation state of colalt.The CoOOH-coated spherical Ni(OH)_2 showed a higher active material utilization in comparison with the regular CoOOH-coated spherical nickel hydroxide.
