论文摘要
可充电电池中的电换电气可增强电极表面树突的生长。在电池中，将低分子量聚合物添加到电解质中会导致形成较高的聚合物浓度在电极附近。这是由于金属电极与溶解在电解质中的聚合物之间吸引力的范德华力。范德华力充当电解质上的恢复身体力，并反对扰动的生长。使用线性稳定性分析，我们表明这种力与电向感染的流相反。这增加了电交流开始所需的临界电压。
Electroconvection in rechargeable batteries enhances the growth of dendrites at the electrode surface. The addition of low molecular weight polymers to the electrolyte in batteries results in the formation of a thin layer of higher polymer concentration near the electrode. This is due to van der Waals forces of attraction between the metal electrode and the polymers dissolved in the electrolyte. The van der Waals forces act as a restoring body force on the electrolyte and oppose the growth of perturbations. Using linear stability analysis, we show that this force opposes electroconvective flow. This increases the critical voltage required for the onset of electroconvection.
