Redox-active, porous pyrene tetraone dendritic polymers as cathode materials for lithium-ion batteries

Abstract

Redox active, insoluble pyrene tetraone based dendritic porous polymers were synthesized by using different catalyst loadings and work-up procedures. The dendritic polymers were investigated by gas sorption analysis for their porosity and characterized with respect to their properties as active material in cathodes of lithium ion secondary batteries. Electrochemical measurements by means of cyclic voltammetry and galvanostatic cycling show reversible redox activity and specific capacities of up to 137 mA h g−1 with a capacity retention of 86% after 50 cycles.
