Embodiment Construction

[0012] Pour 350Kg of pure water that has passed the experience inspection into the barrel, and observe the pH value. If the pH value of the pure water is within the range of 3<PH<7, it meets the requirements. If it exceeds this range, replace the water. If the temperature of the pure water used is lower than 20°C, the water should be heated to about 25°C with a heater first. After the PH value and temperature of the pure water used meet the process requirements, adjust the speed to 500 rpm, add 1.5Kg of anhydrous sodium sulfate to the water in the bucket and stir for 2-3 minutes. Then press the stop button and measure the pH value of the solution. The pH value should be within the range of 5<PH<7. 5. Add 20ml of phosphoric acid and stir at 500 rpm for 1-2 minutes. If the measured pH value is still higher than 5, the solution should be discarded. If the pH value of the solution meets the process requirements, record the pH value and temperature of the solution. Slowly add 20K...

Abstract

The invention provides a preparation method of gel electrolyte for a lead-acid battery. The preparation method comprises the following steps of: adding sodium sulfate into pure water and fully mixing, wherein a phosphoric acid solution can be added to regulate when necessary; slowly adding aerosil when a pH value meets requirements; stirring at different rotational speeds according to different stages to fully stir and uniformly mix the aerosil; and adding phosphoric acid serving as an additive when the aerosil is fully mixed, and fully and uniformly stirring to obtain lacteal gel electrolyte. The electrolyte has small internal resistance and good gel thixotropy; and the capability of battery charging and high current discharging of the prepared gel storage battery are greatly improved, and the cycle life of the prepared gel storage battery is greatly prolonged.

Description

technical field [0001] The invention relates to the manufacture of a lead-acid battery, in particular to a method for preparing a colloidal electrolyte for a lead-acid battery. Background technique [0002] Gel batteries represent the advanced level of lead-acid battery development, and colloidal electrolyte is the key technology for making colloidal batteries. At present, the preparation method of colloidal electrolyte generally has more raw materials and complicated process, which greatly increases the impurity content of the colloidal solution and the production cost, and seriously restricts the charge acceptance and high-current discharge capacity of the colloidal battery. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a preparation method of colloidal electrolyte for lead-acid batteries with low production cost, which can effectively improve battery charge acceptance capacity, high c...
