退火处理对复相La-Mg-Ni系贮氢合金的组织和电化学行为影响较大,介绍了近年来La-Mg-Ni系贮氢合金退火后,合金中Mg含量、微观结构、压力-组成-温度(PCT)特性曲线以及电化学行为的研究状况。分析了复相La-Mg-Ni系贮氢合金的发展应用仍需解决的问题,旨在为提高贮氢合金的电化学性能提供思路和依据。
Annealing treatment has a great influence on the microstructure and electrochemical behavior of La-Mg-Ni based hydrogen storage alloys. The effects of Mg content, microstructure, pressure- Composition - temperature (PCT) characteristic curve and electrochemical behavior of the study. The problems that still need to be solved in the development and application of the multi-phase La-Mg-Ni hydrogen storage alloy are analyzed. The purpose is to provide ideas and basis for improving the electrochemical performance of the hydrogen storage alloy.
