Problems solved by technology

[0002] Ni-MH battery is a traditional product. At present, the battery is traditionally formed by the traditional formation process. The sealed battery must be pre-charged and put on hold for a long time (10-24h) with a small current of 0.002-0.05C. The formation process is cycled 2-3 times, which consumes time for testing. Long, and a large number of pre-charging and forming equipment are required in the production process, thus increasing the battery production cost

Embodiment 1

[0038] A method for forming a long-life high-temperature battery, comprising the following steps:

[0039] Step 1. Positive electrode production: Add 88% of the positive electrode active material nickel hydroxide, 5% of the conductive agent, 1% of the additive, and 2% of the binder, and add an appropriate amount of pure water into the mixer to mix evenly to make a slurry, and then pass The wet drawing process makes the slurry material filled into the nickel foam conductive matrix, controls the thickness, and makes the positive electrode sheet;

[0040] Step 2. Negative electrode production: According to the weight percentage of hydrogen storage alloy powder 94%, conductive agent 1.5%, additive 1%, and adhesive 2%, add an appropriate amount of pure water and put it into a mixer to mix evenly to make a slurry, and then pass it through wet method Slurry process The slurry is coated on the conductive substrate porous nickel-plated steel strip or copper grid, and the amount and siz...
