分析了储氢合金电极失效的四种基本理论,即合金颗粒粉化、元素氧化、吸氢非晶化与释氢品化、电化学腐蚀机制,并综述其研究进展,提出延缓合金电极容量衰减,改善其循环性能的有效控锚途径。
Analysis is made of the basic mechanics about efficacy loss of the electrode, such as pulverization of alloy particle, oxidation of element, amorphous after hydrogen absorption and crystalline after hydrogen desorption,and electrochemical corrosion. The latest research is reviewed. The way how to restrain or lower capacity degradation of electrode and improve cyclic property of hydrogen storage alloy electrode is introduced.
