Battery electrolytes can have a significant influence on various macroscopic performance aspects of the battery such as internal heating, charging time and capacity fade. Since the molecular level electrolyte transport properties directly influence the system level performance, a multiscale study is necessary for optimal electrolyte selection. In this work, we conduct a multiscale comparative study of two commonly used Na ion battery electrolytes NaClO4 and NaPF6 in the non-aqueous solvent EC:DMC. Using a system level physics based model, combined with lower length-scale simulations, we compare system level performance metrics such as charging time and internal heat generation for both these electrolyte salts. Studies such as these can be very effective in identifying optimal electrolytes for next generation Na ion batteries.
