Polymeric binder based on PAA and conductive PANI for high performance silicon-based anodes

Abstract

A novel polymeric binder, PAA–PANI, was prepared which effectively controls the uniformity of a Si anode. PANI provided electrical conductivity for this system, and furthermore participated in an acid–base interaction with PAA and as a result displayed remarkable mechanical properties. These electrical and mechanical properties together apparently led to PAA–PANI having yielded stable cycling and high utilization of the active Si material even after 300 cycles.
