Ni(OH)_2电化学性能改进研究的现状和展望

Progress and Tendency in Improving Electrochemical Performances of Ni(OH)_2

氢氧化镍是重要的电池正极材料,其电化学性能的优劣直接决定电池的放电和存储性能。本文介绍了氢氧化镍的充放电机理,简要综述了球形β Ni(OH)2的改性、纳米Ni(OH)2的开发和掺杂α Ni(OH)2等的研究现状,并指出鉴于目前β Ni(OH)2的开发已接近极限,纳米Ni(OH)2及α Ni(OH)2材料的研究和开发前景将会十分广阔。

Ni(OH)_2 is the active material for positive electrodes of rechargeable alkaline batteries such as Cd-Ni,Zn-Ni,Fe-Ni and MH-Ni batteries.The issue of how to improve the electrochemical properties of Ni(OH)_2 is introduced and what to do in the future is indicated.
