摘要：

针对MnO2/Ni（OH）2@Ni复合电极材料制备工艺复杂的问题，提出快速温和的绿色制备技术.以MnCl2·4H2O、H2O2和泡沫镍为原料，水热体系下研究不同反应温度对MnO2/Ni（OH）2@Ni复合电极材料结构、电化学性能的影响.结果表明，在反应温度90℃、水热3 h，成功在泡沫镍上沉积分布均一的MnO2/Ni（OH）2纳米片.测试结果表明，在该条件下制备的MnO2/Ni（OH）2@Ni电极材料展现出优异的电性能，即高的比容量（电流密度为2.5 mA/cm2，放电比容量为7.4 F/cm2）、好的倍率性能、好的循环稳定性（充放电循环500次，容量保持率为78%）.
Abstract:

A fast and mild green preparation technique was presented, aiming at the complex preparation process of MnO2/Ni(OH)2@Ni composite electrode material. In the hydrothermal system, the structure and electrochemical performances of MnO2/Ni(OH)2@Ni composite electrode material were analyzed at different reaction temperatures, using MnCl2·4H2O, H2O2 and foamed nickel as raw materials. The uniform MnO2/Ni(OH)2 nanosheets were successfully grown on Ni foam at 90℃ for only 3 h. The test result shows that the prepared MnO2/Ni(OH)2@Ni electrode material in this condition has the good electrochemical performance, including high specific capacitance (2.5 mA/cm2, 7.4 F/cm2), the good rate capability and the good cycling stability (the capacitance retention of 78% after 500 cycles).
