摘　　要：确定了制备3 Ah SC型MH-Ni蓄电池的工艺参数,分析了电解液组成及用量对电池性能的影响,确定出最佳电解液组成为4 mol/L KOH +3 mol/L NaOH +15 g/L LiOH溶液,最佳加液量为5.0～5.2 g。通过对比实验,选择了多孔结构的集流片并确定了正极板厚度为0.60 mm。对电池进行不同倍率(0.2 C、1 C、5 C、10 C)放电及1 C循环寿命测试,实验结果表明都达到了设计要求。Technologic parameters of 3 Ah SC-sized Ni-MH batteries were introduced. Effects of electrolyte composing and content on electrochemical performance of Ni-MH battery were analyzed. Results show that the optimum electrolyte composing is 4 mol/L KOH +3 mol/L NaOH +15 g/L LiOH and the optimum electrolyte content is 5.0-5.2 g. By contrast experiment porous structural collector was chosen and the electrode thickness of 0.60 mm was confirmed. Test results of discharge at different rates and cycle at 1 C show the electrochemical performance of SC-sized MH-Ni battery reaches design requirement.
