摘　　要：综述了化学均相沉淀法合成α-Ni(OH)_2的方法,在适宜的温度、p H值、镍盐浓度及添加相关的活性剂下能够得到容量高、电压大、循环性能好的α-Ni(OH)_2材料。另外,通过掺杂不同的金属盐来改变其性能,并添加Zn盐、Al盐、Mn盐、铁盐、稀土金属盐等化合物,改良α-Ni(OH)_2结构。其中掺杂Al盐得到的α-Ni(OH)_2性能最好。综述了化学沉淀法以外的一些其它合成α-Ni(OH)_2的方法。The method of the chemical homogeneous precipitation type synthesis of alpha Ni（OH）2 was reviewed. The large capacity, high voltage alpha Ni （OH） 2 materials could be got under the good cycle performance of appropriate temperature, PH, concentration of nickel salt and add related surfactant. Its performance could be changed by many scholars doped with different metal salt. Its structure could be changed by adding zinc salt, AI salt, Mn salt, iron salt, rare earth metal salts and other compounds. The AI salt of alpha Ni（OH）2 performance was best in all metal salts. Except for the chemical precipitation method, also the synthesis of some other type of alpha Ni（OH）2 was summarized.
