| 摘 要： | 研究了稀土元素 L a掺杂对 Ni( OH) 2 晶格的影响 ,发现通过掺杂 ,改变了 Ni( OH) 2 晶格常数 ,降低了Ni2 +的局域能级 ,引入了大量的正缺陷 ,相对于未掺杂晶体 ,其 OH-的数量增多 ,增大了质子扩散的几率 ,因而提高了材料的电化学性能 .

| Abstract: | The effect of doped-La on the lattice of Ni(OH)2 were studied. After doping,the lattice constants of Ni(OH) 2 were changed,the local energy level was lowed.Because of the defects, the amount of OH - is higher than the undoped material.So the coefficient of the proton diffusion was improved and the electrochemical property of the material was enhanced. |
