2012-01-17 11:08:56 admin
The MH-Ni battery is alkaline rechargeable battery without pollution, a new type of high performance. The metal hydride (metal hydride) as anode and nickel hydride as cathode, the nominal voltage of monomer is 1.2V. Its internal structure and a manufacturing method of a cadmium nickel battery with the same, it has the following advantages: 1. High specific energy, is about 1.5-2 times that of the nickel cadmium battery, the capacity can be improve 70-100%, work for a long time; (2) good resistance to overcharge, put the protection characteristics; (3) due to the hydrogen storage alloy to substitute for cadmium as negative electrode, eliminating the environmental pollution of cadmium and its compounds; (4) hydrogen storage materials have a wide range of sources; manufacturing process is simple; nickel cadmium battery swap the is of the nickel cadmium battery replacement. However, Ni MH batteries and nickel cadmium battery, also has the memory function, but it is not very obvious. In recent years, with the electric appliances with the battery work requirements increase, and market competition intensifies, the performance of Ni MH battery also continue to improve and enhance. Mainly used in mobile phones, notebook computer, portable CD, VCD, phone, camera etc..
The main raw material for nickel metal hydride (Ni MH) battery is nickel powder, nickel hydroxide, nickel nitrate, nickel sulfate, ceiling hydrogen storage alloy, steel shell, potassium hydroxide, sodium hydroxide etc..
