摘    要:采用缓冲溶液法制备Mn掺杂Ni_(1-x)Mn_x(OH)_2(x=0.1,0.2,0.3,0.4)。X射线衍射(XRD)测试表明x=0.1和0.2的样品主要是由β相组成;扫描电子显微镜(SEM)和氮气吸附-脱附测试表明掺杂Mn样品比不掺Mn的商用β-Ni(OH)2的颗粒更细小、多孔;恒流充放电测试表明,这种电极具有优良的高倍率性能,当x=0.2,电流密度800 mA·g-1时放电比容量为288.8 mAh·g-1,同等条件测试的商用β-Ni(OH)2放电比容量为198.7 mAh·g-1,循环580圈后仍有276 mAh·g-1的放电比容量,其衰减率为4.1%,而同等测试条件下的其它4种样品衰减率分别为46.1%(商用β-Ni(OH)2)、13.0%(x=0.1)、25.6%(x=0.3)、34.1%(x=0.4),可见这种Mn掺杂电极材料适合大电流密度充放电,能够改善镍电极的循环稳定性,降低镍电极成本。

关 键 词:缓冲溶液法  Ni1-xMnx(OH)2  倍率性能  循环稳定性
