Abstract: Binder is an important material for making electrodes, which can significantly influence the electrochemical performances of Li-ion batteries. Water-based binders have attracted much attention in recent research because the proper binders could enhance the adhesion with less amount. Moreover, binders also play an important role on improving electrochemical performance and restraining volume expansion. The application of water-based binder makes the production process more environmental friendly and cheaper. The application of water-based binder for cathode and anode in Li-ion batteries was reviewed in this paper. It was pointed out that the electrodes prepared with water-based binder possessed excellent performances and capacious application prospects. The features, merits and demerits for different kinds of binders were discussed. It shows that water-based binder can be used to replace the organic solvent-based binder polyvinylidene fluoride(PVDF). Finally, the developing trend of electrode binder was summarized.

Key words: Li-ion batteries, water-based binder, electrochemical performances
