방전 및 유지기에서의 납축전지 성능예측 Prediction of the Performance of Lead Acid Cell during Discharge and Rest Peroid

The discharge performance of the lead acid cell at high and low current densities was observed to verify the model by comparing the experimental results at room temperature with numerically predicted values. Our model was based on the macroscopic homogeneous model and considered the diffusion-precipitation reaction in the kinetics of the negative electrode and the effect of the electrolyte concentration. The change of the electrolyte concentration, porosity variation and cell voltage behavior during discharge and rest period were examined. The discharge current was high at low temperature, the active material utilization of the positive electrode was very low and the performance of the cell was controlled by the mass transfer resistances between the positive electrode and the reservoir, and between the separator and the negative electrode.
