Description
Polyacrylates were applied as binder for the electrode of a particulate mixture of silicon, graphite, and Ketjen black for lithium-ion batteries. We found that poly(alkali acrylate) binder remarkably improved the electrochemical lithiation and delithiation performance of the silicon-graphite electrode compared to that of conventional binders. The polyacrylate coating on Si and graphite particles suppressed the electrode deterioration. When the electrode was prepared with 30 wt% poly(sodium acrylate) binder, the higher specific capacity and initial efficiency were obtained with much improved cycleability.
