Simulation and analysis of electrode foil powder sintering based on phase-field method
Using the phase field method,particle sintering and shrinkage of pores of the powder-coated electrode foil was simulated.Five different types of spatial structure pore models were established based on the actual sintered pore data.By simulating the changes in the sintering pore sizes of different particle sizes,the effectiveness of the model simulation was validated.Using a single-factor analysis,the influence of sintering temperature and pore type changes on the final pore area was explored.The results indicate that sintering temperature mainly affects the inter-particle sintering rate.The pore type influences the final sintered morphology of the aluminum powder and subsequently affects the sintered pore area,with the triangular pores having the smallest area.This model has significant reference value for the prediction of the effective surface area of powder-coated electrode foils under different sintering temperatures,times,and pore types.
