Research Progress in Characterization Techniques of Polymer Binders for Lithium-ion Battery
Binders play an important role in the manufacture of lithium-ion battery(LIBs)electrodes.Binders can integrate the electrochemically active material and conductive agent into the surface of the collector,which directly affects the diffusion of ions and electrons in the electrode,the efficiency of REDOX reaction,the stability of the electrode structure and the formation of solid electrolyte interface film(SEI).Therefore,the research on the characterization technology of binders is very important for LIBs.In this paper,the research progress of polymer binder characterization for LIBs is reviewed.The intrinsic properties,electrode microstructure and electrochemical properties of the binder are mainly introduced.Finally,in order to provide technical support for the development of polymer binders,the applications of in situ characterization and theoretical simulation are prospected.
