| Use | Uses large-scale bag-type and open-type cadmium-nickel batteries are mainly used in industrial, military, aviation and other fields requiring high-power discharge, such as starting power supply of railway locomotive, switching power supply of power system, mine emergency power supply, starting power supply for artillery and armored vehicles, emergency starting power supply for aircraft engines and generators, etc. Cylindrical cadmium-nickel sealed batteries are mainly used for power tools, shaving machines and video cameras. Small button type cadmium nickel battery is mainly used for small current low rate discharge calculator, cordless phone, toys, etc. |
Taking a cylindrical cadmium-nickel sealed battery as an example, the positive electrode powder and the negative electrode powder are mixed according to the ratio, and filled in the perforated nickel-attached steel strip. The polar plates are made by drawing, rolling, sintering, forming or applying paste, drying, tabletting, etc., and a diaphragm is inserted between the positive and negative electrode plates, wound into a column, and put into the battery case, the battery is made by welding the bottom, coating sealant, adding electrolyte solution, welding cover and sealing.
