Abstract
A powdered positive mixture, a powdered separator mixture, and a powdered negative mixture are filled sequentially into a mold in layers, then the layers of the positive mixture, the separator mixture and the negative mixture are compacted in the mold to form a laminated tablet. The laminated tablet is placed in a container, and is impregnated with an alkaline electrolyte queous solution. Then the container is sealed to produce an alkaline cell.
Claims25
An alkaline cell manufacturing method comprising the steps of:
- sequentially filling a positive mixture powder, a separator mixture powder and a negative mixture powder into a mold;
- compacting said positive mixture powder, said separator mixture powder and said negative mixture powder in said mold so as to form a laminated cell tablet;
- placing said laminated cell tablet into a container;
- impregnating said laminated cell tablet with an alkaline electrolyte solution;
- and
- sealing said container so as to produce an alkaline cell.
An alkaline cell manufacturing method comprising steps of:
- (a) placing into a mold and compacting a positive mixture so as to form a compacted positive mixture layer;
- (b) placing a separator mixture powder over said compacted positive mixture layer and compacting said separator mixture powder in said mold so as to form a separator mixture layer;
- (c) placing a negative mixture powder over said compacted separator mixture layer and compacting said negative mixture powder in said mold so as to form a negative mixture layer;
- (d) firmly compacting said positive mixture, said separator mixture and said negative mixture in said mold so as to form a laminated cell tablet;
- (e) removing said laminated cell tablet from said mold and placing said laminated cell tablet in a container;
- (f) impregnating said laminated cell tablet with an alkaline electrolyte aqueous solution in said container;
- and
- (g) sealing said container so as to produce an alkaline cell.
