掺锰的氢氧化镍的制备、结构及充放电性能
Synthesis and Structure and Charge-Discharge Performance of Ni(OH)2 Substituted by Manganese
【摘要】 采用固相反应法合成取代含量为 30 % (摩尔分数 )的锰取代氢氧化镍 ,其中合成过程中加入还原剂所得的样品为α型氢氧化镍 ,该样品做成的电极具有更优良的电化学性能 :电极可逆性好 ,充电平台低 ,放电平台高 ,容量更大 .
【Abstract】 Ni(OH)2 including 30% Mn was synthesized by solid state reaction. The α type Ni(OH)2 was obtained when a kind of salt was used as reducing agent in the synthetic process. The structures and electrochemical behaviors of two samples were characterized by means of X-ray diffraction and constant current charge-discharge experiment respectively.
