According to the research results of internal and external spherical nickel hydroxides,it was shown that they were different in such respects as chemical composition,crystal structure and Crystallite size etc. The external nickel hydroxides represented by Japan were excellent in the electrochemical performances such as longer discharge voltage platform and longer charge-discharge cycle life under high current because of their branch-crystalline-form and smaller crystallite size. On the other hand,the internal nickel hydroxides were inferior to the external ones in electrochemical performances because of their grain-crystalline-form and bigger crystallite size.

对国内外球形氢氧化镍的研究表明,它们在化学成分、晶体结构、晶粒度等方面存在差异。日本等国外氢氧化镍晶形呈枝晶状,晶粒度小,表现在电化学性能上则具有放电电压平台长、大电流充放电循环寿命长等优点;而国内氢氧化镍晶形普遍呈粒晶状,晶粒度较大,故电化学性能与日本等国外产品相比有一定差距。
