中文摘要：
用低热固相反应法制备β-Ni（OH）2样品，用XRD和SEM研究了样品的晶体结构和表面形貌；采用恒流充放电和循环伏安测试研究了样品的电化学性能，结果表明：低热固相反应法合成的β-Ni（OH）2样品比化学沉淀法制备的样品可逆性好，放电比容量更大（最高分别为266mAh／g和236mAh／g），放电电压平台更高。
英文摘要：
β-Ni（OH）2 sample was prepared by low-heating solid state reaction method. The crystal structure and surface morphology of the sample were studied by XRD and SEM. The electrochemical performance of the sample was studied by constant chargedischarge and cyclic vohammogram tests. The results showed that the reversibility, discharge specific capacity and discharge potential platform of the sample prepared by low-hcating solid state reaction method were superior to that of the sample prepared by chemical precipitation method. The maximal discharge specific capacity was 266 mAh/g and 236 mAh/g, respectively.
