Embodiment ( 1

[0011] Adopt the present invention to prepare sealing oil for nickel-metal hydride batteries. First, use an electronic balance to weigh 10Kg of battery-grade asphalt, put it in a stainless steel pot, and the effective volume of the stainless steel pot is 25L. Heat the stainless steel pot to melt the pitch, and stir while heating After the asphalt is completely melted, cool until the asphalt temperature is 40-50 degrees, weigh 6Kg of industrial gasoline, slowly add it into the stainless steel pot, and stir while adding. Cool to 25-30 degrees, the specific gravity of the test seal oil is 0.91g / cm 3 , into containers for later use.

[0012] Use the sealing oil for nickel-metal hydride batteries of the present invention to make 10,000 50AA 2500mAh batteries, and use manual or mechanical methods to evenly coat the sealing oil on the inner wall of the battery shell mouth slot. After the battery activation, take 1000 batteries, charge 50%, store them at an ambient temperature of 20-...

Abstract

The invention belongs to the technical field of nickel-hydrogen battery manufacturing and provides a method for preparing sealing oil of nickel-hydrogen batteries. This Ni-MH battery sealing oil preparation method includes the following steps: select battery-grade asphalt, heat and stir in a container to melt the asphalt completely; cool to 40°C-50°C, and set the mass ratio of asphalt to gasoline at 1:0.2-0.8 Slowly add gasoline in a proportion of 100%, stirring while adding; cool to room temperature, and seal the package for later use. According to the method for preparing the sealing oil of the nickel-metal hydride battery of the present invention, gasoline is relatively less harmful to the human body, and gasoline is used as a solvent to prepare the sealing oil, which can achieve the same sealing effect.

Description

technical field [0001] The invention relates to a nickel-hydrogen battery sealing oil, in particular to a method for preparing the nickel-hydrogen battery sealing oil. Background technique [0002] The traditional preparation method of Ni-MH battery sealing oil uses toluene or xylene as a solvent to dissolve pitch (battery-grade pitch) for Ni-MH batteries. The sealing oil prepared in this way can achieve a good sealing effect. [0003] However, toluene and xylene are toxic chemical materials, which can enter the human body through inhalation, ingestion, and skin absorption to endanger human health. In the process of preparing and using sealing oil, the pollution to the environment is relatively large, and it will endanger the health of workers. Contents of the invention [0004] The object of the present invention is to overcome the drawbacks of the existing cylindrical nickel-hydrogen technology, and provide a method for preparing sealing oil for nickel-hydrogen batteries...
