[0073] In one embodiment, the preparation method of described coated nickel powder comprises the following steps:
[0074] Dissolving nickel source and boron source in a solvent, adding organic matter to prepare nickel boride organic precursor;
[0075] mixing and stirring the nickel boride organic precursor and nickel powder, evaporating the solvent, and preparing nickel powder coated with organic matter;
[0076] The organic matter is selected from one or more of perchlorethylene, polyvinyl alcohol and ethyl cellulose. Preferred is polyvinyl alcohol.
[0077] In one embodiment, the nickel source is Ni(CO) 4 , the boron source is boric acid.
[0078] Alternatively, the solvent can be acetone, which is subsequently removed by evaporation. Optionally the temperature at which the solvent is evaporated is 80°C ± 5°C.
[0079] It can be understood that after evaporating the solvent, a step of pulverizing and grinding the product is also included to adjust the size of the coat...
Embodiment 1
[0111] This embodiment provides a nickel electrode slurry, a resistor and a method for preparing the resistor, in parts by weight, the steps are as follows:
[0112] 1) Take the first nickel powder with a particle size of 0.1 μm to 1 μm, the second nickel powder with a particle size of 1 μm to 3 μm, and the third nickel powder with a particle size of 3 μm to 10 μm, and mix them in a weight ratio of 2:1.5:1 to obtain a mixture type nickel powder.
[0113] 2) In 1L of acetone, add 1L of Ni(CO) 4 and 300g of boric acid, then add 0.8L of polyvinyl alcohol, and mix thoroughly to obtain a nickel boride organic precursor, then add 800g of nickel powder, heat to 80°C, evaporate and dry to remove acetone, then pulverize and grind the product to obtain a particle size of 0.5μm~2μm nickel powder coated with organic matter.
[0114] 3) 1L of terpineol, 1L of mineral spirits and 2kg of ethyl cellulose were mixed, then heated to 90° C., and stirred at 90° C. for 2 hours to dissolve the et...
