Polyacrylate anion was used as binder of graphite electrode in lithium-ion cell to modify the interface. Compared with polyvinylidene fluoride, the coulombic efficiency at the initial cycle was improved by polyacrylic acid and alkali polyacrylates in an ethylene carbonate (EC) based electrolyte. Although the polyvinylidene fluoride electrode showed a huge irreversible capacity in propylene carbonate (PC) electrolyte, the polyacrylate modified graphite demonstrated highly reversible lithium intercalation in a PC electrolyte as well as in an EC based electrolyte.
