Embodiment 1
[0022] A method for manufacturing a packaged plate of a bag-type cadmium-nickel alkaline storage battery, comprising the following steps:
[0023] (1) Lumping: powdered positive electrode active material (mainly composed of 79% nickel hydroxide, 3% barium hydroxide, 18% phosphorus flake graphite powder) and negative electrode active material (The weight percent composition is mainly 64% cadmium hydroxide, 3% graphite powder, and 33% ferric oxide) respectively pressed into thicknesses of 3.3 ± 0.15mm and 1.9 ± 0.15mm by a briquetting machine, and the length is 202mm Cube tiles with a width of 11.8 -0.3 0 mm, control the weight of positive and negative small pieces to 15.0 0 +0.16 g and 10.9 0 +0.16 g. While briquetting, wrap the positive and negative electrode blocks in a flat perforated steel belt bag of 0.1mm × 25mm and 0.1mm × 23mm respectively through the baler without interruption to make the positive and negative electrode plates long strip;
[0024] (2) Strip embo...

[0031] A method for manufacturing a packaged plate of a bag-type cadmium-nickel alkaline storage battery, comprising the following steps:
[0032] (1) Lumping: powdery positive electrode active material (weight composition is 79% nickel hydroxide, 3% barium hydroxide, 18% phosphorus flake graphite powder) and negative electrode active material (weight composition 64% of cadmium hydroxide, 3% of graphite powder, and 33% of iron tetroxide) were respectively pressed into cube blocks with a thickness of 2.4±0.15mm and 1.7±0.15mm, a length of 202mm, and a width of 10.8 -0.3 0 mm, control the weight of positive and negative small pieces to 10.9 0 +0.16 g and 7.2 0 +0.16 g. While briquetting, wrap the positive and negative electrode blocks in a flat perforated steel belt bag with a size of 0.1mm × 23mm and 0.1mm × 21mm respectively through a baler without interruption to make the positive and negative electrode plates long strip;
[0033] (2) Strip embossing: The above-mention...
Embodiment 3
[0040] A method for manufacturing a packaged plate of a bag-type cadmium-nickel alkaline storage battery, comprising the following steps:
[0041] (1) Lumping: powdery positive electrode active material (weight composition is 79% nickel hydroxide, 3% barium hydroxide, 18% phosphorus flake graphite powder) and negative electrode active material (weight composition 64% of cadmium hydroxide, 3% of graphite powder, and 33% of ferric oxide) were respectively pressed into cube blocks with a thickness of 1.8±0.15mm and 1.6±0.15mm, a length of 202mm, and a width of 9.8 -0.3 0 mm, control the weight of positive and negative small pieces to 7.9 0 +0.16 g and 5.2 0 + 0.16 g. While briquetting, wrap the positive and negative electrode blocks in a flat perforated steel belt bag of 0.1mm×19mm and 0.1mm×19mm respectively through the baling machine without interruption to make the positive and negative electrode plates long strip;
[0042] (2) Strip embossing: the above-mentioned posit...
