摘　　要：研究了化成制度对MH/Ni电池综合性能的影响。实验结果表明:化成制度对电池容量、放电平台、内阻及自放电等方面都有重要影响。XRD的测试结果证明了大电流化成时,镍电极将产生γ NiOOH,而小电流化成时则未测出γ NiOOH产生。通过实验确定了适合于实际生产的化成制度。The effects of formation procedurces on the electrochemical performance of MH/Ni battery were studied.The results showed that the selection of formation procedures had an effect on the battery performance such as the capacity,the plateau voltage,the internal resistance and the selfdischarge.The XRD testing results indicated that γNiOOH formed through the nickel electrode when activated by large current,but no γNiOOH formed when activated by small current.The formation procedures developed in this work was suitable for volume production.
