Abstract

Adiponitrile (ADN) as a promising solvent is widely used in high-voltage system. However, its effect on the graphite is not so ideal, for the reason that thermal instability at low potential and lower lowest unoccupied molecular orbital (LUMO) energy (-0.02223 eV) of ADN result in the reduction decomposition preferentially. Lithium difluoro (oxalate) borate (LiODFB) and ethylene carbonate (EC) might remedy the defect resulting from ADN due to its good film forming property. Different contents of ADN have the influence on the electrochemical performance for mesophase carbon (MCMB) cells, it is largely related to the nature of the SEI film formed on the surface of anode material. Three electrolytes with suitable contents of ADN were chosen for investigation, LiODFB-based electrolyte with the ADN content of 20 % put up the best electrochemical performance.
