摘要：PURPOSE:To obtain an alloy negative electrode having good cycle life in

overdischarge by using an alloy selected from a group comprising a specified wt% of

bismuth, cadmium, tin, and lead as a negative electrode. CONSTITUTION:In a

rechargeable electrochemical device having a negative electrode comprising an alloy

which reversibly absorbs and desorbs alkali metal ion, a negative electrode alloy is

selected from a group comprising 20-75wt% bismuth, 15-80wt% cadmium, an the balance

tin and lead. The alloy comprising a specified composition of tin, lead, bismuth, and

cadmium is melted, and a nickel expanded metal current collector is immersed in the

melted alloy, then taken out, and dried. The current collector is rolled to the thickness of

0.2mm, and a part of expanded metal is exposed and a lead 6 comprising nickel ribbon is

welded thereon. Thereby, an alloy negative electrode having good cycle life in

overdischarge is obtained.
