graphitic electrode. [ 8 ] Unfortunately, when applied in a dualgraphite battery, the EC molecules in the electrolyte can bind tightly with PF 6 − anions, and prevent the intercalation of these anions into the interlayer spaces of graphite positive electrodes. [ 9 ] Recently, with the developments of novel electrolyte formulas, several studies have reported signifi cantly improved reversibility of dual-carbon batteries. [ 10 ] Read et al. reported a reversible dual-graphite battery with simultaneous accommodation of Li + and PF 6 − in graphitic structures enabled by a high voltage electrolyte based on fl uorinated solvent and additive. [ 10a ] The battery demonstrated a reversible capacity of 60 mAh g −1 and a capacity retention of 62% after 50 cycles at C/7 rate. Rothermel et al. reported a dual-graphite battery based on a mixture of lithium bis-(trifl uoromethanesulfonyl)-imide (LiTFSI) and ionic liquid with SEI-forming additive. This electrolyte formula not only enabled stable TFSI − intercalation into the graphite positive electrode, but also allowed highly reversible intercalation of Li + into the graphite negative electrode.
