摘要
贮氢合金的表面性质对于它的电化学应用十分重要。AB5病型贮氢合金虽然具有活化性能好 ,容量在2 6 0mA·h/g～ 32 0mA·h/g是目前生产MH Ni电池负极的主干材料。但是AB5,型贮氢合金在反复充放电过程中抗氧化和抗粉化的能力很差 ,导致放电容量的迅速降低。综述和比较了近年来对AB5,型贮氢合金表面处理的研究情况 。
The surface property of hydrogen storage alloy is very important for its electrochemical application.AB 5 hydrogen storage alloy has good activation property and discharge capacity of 260mAh/g～320mAh/g and is the main negative material for MH Ni battery.But the negative electrode with AB 5 hydrogen storage alloy has low antioxidation,antipulverization and anticorrosion.The relationship between the surface property and electrochemical performance of the alloy is discussed with the previous research.The development status of the different surface treatments for AB 5 alloys in resent years are reviewed and compared.
