Conjugated polymers possessing polar functionalities were shown to effectively anchor single walled carbon nanotubes (SWNTs) to the surface of high capacity anode materials and enable the formation of electrical networks. Specifically, poly[3-(potassium-4-butanoate) thiophene] (PPBT) served as a bridge between SWNT networks and various anode materials, including monodispersed Fe3O4 spheres (sFe(3)O(4)) and silicon nanoparticles (Si NPs). The PPBT pi-conjugated backbone and carboxylate (COO-) substituted alkyl side chains, respectively, attracted the SWNT,pi-electron surface and chemically interacted with active material surface hydroxyl (OH) species to form a carboxylate bond. Beneficially, this architecture effectively captured cracked/pulverized particles that typically form as a result of repeated active material volume changes that occur during charging and discharging. Thus, changes in electrode thickness were suppressed substantially, stable SEI layers were formed, electrode resistance was reduced, and enhanced electrode kinetics was observed. Together, these factors led to excellent electrochemical performance.
