摘要：
LPCNi3.55C0.75Mn0.4Al0.3 hydrogen storage alloy was investigated, and the effects of thickness of its strip casting ingots(as-east) on the electrochemical performances were discussed. It was found that the 0.2 C discharge capacity increased with the increase of the thickness (from I mm to 10 mm) of the ingots, mainly due to the enlargement of the unit cell volume; Among the thickness of the ingots in our study, 10 mm sample showed a better activation property; LPCNi3.55Co0.75Mn0.4Al0.3 alloy with 10mm showed higher comprehensive properties than those with other thickness under IC rate.
