Problems solved by technology

However, the test cycle life of the current battery is relatively short (100%DOD cycle times are less than 100 times, 60%DOD cycle times are not more than 400 times), and related requirements (100%DOD cycle times are at least 200 times, 60%DOD cycle times are at least 1500 times) there is a certain gap
After long-term test verification and analysis, it is confirmed that the main factors affecting the battery cycle life are the acid content of the plate lead paste, the amount of active material on the plate, the density and retention of the electrolyte, the compression ratio of the diaphragm assembly, the placement of the battery plate, etc. , many of the above-mentioned factors of the existing batteries are set unreasonably and irregularly, and the manufacturing process needs to be improved.

Embodiment Construction

[0007] The GFM-500 sample battery was produced respectively by using the existing technology and the method of the present invention, and the relevant parameters are compared in Table 1.

[0008] Table 1:

[0009]

[0010] The battery produced by the method of the present invention is compared with the existing battery cycle life test as shown in Table 2.

[0011] Table 2:

[0012]

[0013] It can be seen through test comparison that the battery (sample 9) made by the present invention # ~17 # and 18 # ~26 # ) 100% DOD cycle times more than 200 times, 60% DOD cycle times more than 1500 times, meet the requirements of relevant standards, compared with the existing battery (sample 1 # ~8 # ) The cycle life is significantly improved.

Abstract

The invention discloses a method for manufacturing a long-life lean liquid lead-acid storage battery. The main improvements are as follows: the battery plates are placed horizontally; Ah; the assembly compression ratio of the pole group is not less than 25%; the acid content of the positive electrode paste does not exceed 45g / kg, and the acid content of the negative electrode paste does not exceed 50g / kg. The 100% DOD cycle number of the lead-acid battery produced by the method exceeds 200 times, and the 60% DOD cycle number exceeds 1500 times, which is significantly improved compared with the existing batteries.

Description

technical field [0001] The invention relates to the field of manufacturing lead-acid batteries, in particular to a method for manufacturing long-life lean liquid lead-acid batteries. Background technique [0002] As the concept of energy saving and environmental protection continues to become popular among the people, in view of the gradual warming of the global climate, people have higher and higher requirements on the life of the lean liquid lead-acid battery, especially the battery used in circulation. However, the test cycle life of the current battery is relatively short (100%DOD cycle times are less than 100 times, 60%DOD cycle times are not more than 400 times), and related requirements (100%DOD cycle times are at least 200 times, 60%DOD cycle times are at least 1500 times) there is a certain gap. After long-term test verification and analysis, it is confirmed that the main factors affecting the battery cycle life are the acid content of the plate lead paste, the amo...
