以粉末涂层型电极箔为研究对象,采用相场法对颗粒烧结及孔隙的收缩进行仿真模拟,根据实际烧结孔隙数据建立了五种不同空间结构类型的孔隙模型,通过模拟计算不同粒径烧结孔隙变化,验证了模型模拟的有效性.采用单因素分析法探究了烧结温度及孔隙类型的改变对最终孔隙面积的影响规律,结果表明:仿真模拟中烧结温度影响颗粒间烧结速度;孔隙的类型影响最终铝粉烧结形貌,并进一步影响烧结形成的孔隙面积,其中以三角形孔隙面积最小.模型的建立对不同烧结温度、烧结时间、孔隙类型的粉末涂层型电极箔有效表面积的预测具有重要参考价值.
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.
