Button type air battery
专利汇可以提供Button type air battery专利检索，专利查询，专利分析的服务。并且PURPOSE:To improve the contact of the external section of a catalytic layer with a positive electrode case that arranges the catalytic layer inside, reduce the internal resistance value of a bottom type air battery, and stabilize discharge performance by making the diameter of the contact section with the external section of the catalytic layer of the positive electrode case smaller than that of another section. CONSTITUTION:An air supply hole 2 is provided at the bottom of a positive electrode case 1 and air diffusion paper 3 is arranged in the recess of the bottom and then a fluororesin water repellent coat 4 is inserted on it. In addition, a catalytic layer 5 obtained by filling a nickel net with the catalytic material formed by mixing active carbon, acetylene black, and polytetrafluoroethylene acting as a bonding agent is inserted on it. Finally, a positive electrode side assembly body is completed by inserting a separator 6 in the positive electrode case 1. The negative electrode assembly body is completed by filling a sealing plate 8 that engages with an insulating sealing ring 7 around its edge, with a negative electrode active material 9 together with an alkaline electrolyte. The positive and negative electrode assembly bodies are engaged with each other and the opening section of the positive electrode case is bent inside. Finally, a button type air battery is completed by pressing and reducing, by means of a roller, the diameter 1' of the outside edge section of the case 1 with which the external section of the catalytic layer is made to touch.，下面是Button type air battery专利的具体信息内容。
