The capacity of the battery is closely related to the plate design, battery design selection ratio, plate thickness, plate manufacturing process, battery assembly process, etc.
①. The influence of plate design: Under the same specific surface area and weight, the utilization rate of plate active materials will be different for wide and short type and thin and tall type. Generally, the corresponding plate size is designed according to the actual size of the customer's battery.
②. The influence of battery plate selection ratio: Under the same battery weight, different plate ratios will have different battery capacities. Generally, the selection is based on the actual use of the battery. The utilization rate of thin plate active materials is higher than that of thick plate active materials. Thin plates are more suitable for scenes with high-rate discharge requirements, and thick plates are more focused on batteries with cycle life requirements. Usually, the plate is selected or designed accordingly according to the actual use and technical requirements of the battery.
③. Thickness of the plate: When the battery design has been finalized, if the plate is too thin or too thick, it will affect the tightness of the battery assembly, the internal resistance of the battery, the acid absorption effect of the battery, etc., and ultimately affect the battery capacity and life. In general battery design, the plate thickness tolerance of ±0.1mm and the range of ±0.15mm should be considered, which will bring about the impact.
④. The impact of the plate manufacturing process: The particle size (oxidation degree) of the lead powder, the apparent specific gravity, the lead paste formula, the curing process, the formation process, etc. will affect the capacity of the plate.
⑤. Battery assembly process: The selection of the plate, the tightness of the assembly, the density of the electrolyte, the initial charging process of the battery, etc. will also have an impact on the battery capacity.
In summary, for the same size, the thicker the plate, the longer the life, but the capacity may not necessarily be larger. The battery capacity is closely related to the type of the plate, the plate manufacturing process, and the battery manufacturing process.
