1.Plate: The thinner the plate, the better the porosity of the active material, making it easier for the electrolyte to penetrate, and the higher the utilization rate of the active material. On the premise that the battery shell remains unchanged, the use of thin plates can increase the number of plates; the larger the plate area, the more active substances for chemical reactions, and the greater the output capacity; shorten the center distance of the plates of the same sex, The internal resistance of the battery can be reduced. On the premise of ensuring sufficient electrolyte, the center distance can be shortened as much as possible to increase the capacity of the battery.

2. Discharge current: As the discharge current increases, the chemical reaction rate will increase, and the pores of the electrode plate will be blocked by the rapidly generated lead sulfate, which will make it difficult for the electrolyte to penetrate into the pores, so that a large number of active materials in the electrode plate cannot be used. Participate in chemical discharge, which makes the discharge capacity of the battery drop rapidly.

3. Temperature influence: When the temperature decreases, the viscosity of the electrolyte increases, the fluidity deteriorates, the electrolyte penetrates into the pores of the electrode plate, and the active material in the pores of the electrode plate cannot be fully utilized, which is the decrease of the discharge capacity of the battery. In general, when the temperature decreases by 1°C, the capacity decreases by about 1% during slow discharge, and about 2% during high current discharge.
