What are the factors that affect the utilization of battery active materials?

When the number of battery active materials is pressed on time, the actual capacity is determined by its utilization rate. The factors that affect the utilization of active materials are as follows: 1 Influence of discharge conditions (1) Under the condition that the total number of active materials remains unchanged, the battery capacity decreases with the increase of the discharge current. Therefore, when talking about battery capacity, the discharge rate must be specified. (2) The capacity of the storage battery and the utilization rate of active material increase with the increase of temperature, which is mainly caused by the change of electrolyte performance. One is the decrease in the citation temperature and the increase in the viscosity of the electrolyte, which makes the ion movement suffer greater resistance, and the ability to diffuse is reduced. The active material cannot be used due to the lack of acid, resulting in a decrease in capacity. The electrolyte resistance is increased by the decrease in temperature. As a result, the internal resistance of the battery increases, the voltage drop increases, and the capacity decreases. (3) The cut-off voltage at the time of termination voltage discharge also slightly affects the calculation of the discharge time. In order to prevent the battery from failing to discharge and damaging the fetters, as well as for comparison between different batteries, the standard has clearly defined the final voltage during discharge at various discharge rates and temperatures. 2 The influence of design parameters (1) When the quality of the active material is pressed, the geometric area directly in contact with the electrolyte is increased, and the thickness of the electrode plate is reduced. Then the utilization rate of the active material will increase. The battery capacity will be added. (2) The influence of electrolyte concentration on battery capacity. In lead-acid batteries, sulfuric acid is also a reactant. The concentration of electrolyte added to the volume on time is the addition of reactants, so in actual use, the electrolyte concentration is within the range , The new battery capacity of the electrolyte concentration is also added. (3) The design parameters of the grid are changed from the ordinary rectangular grid to a radial shape, and the tabs on one side are changed to rely on the high current discharge performance and low temperature of the middle battery. The ability to start and charge can be significantly improved. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
