Production process of Ni-MH battery products
The following diagram illustrates the key stages of our production process for Ni- MH battery products:¡X
Confection
Nickel hydroxide is mixed with other chemicals in a blender to produce anode hybrid powder.
Production of positive electrode plates
The anode hybrid powder is applied onto foamed nickel which is rolled into positive electrode plates by drawing and rolling machines. Electrodes are affixed by spot welding machine.
Production of negative electrode plates
Hydrogen storage alloy powder is applied onto copper wire mesh which is rolled into negative electrode plates.
Assembling
Positive electrode plates are separated from negative electrode plates with diaphragms, and convoluted as combined electrodes through a convolution machine and they encrypted into steel shells. The steel shells will be put into a rolling machine where the groove lye will be inserted. The steel shells encrypted with combined electrodes will be produced as open cells for sealing.
Sealing
Covers are welded onto the open cells and the cells are then sealed by using cappers to form semi-finished battery products for formation.
Formation
Under the processes of formation and examination by using chemical combination machines and examination tanks, the semi-finished battery products will turn into finished products with technical standards.
