Abstract

A study was conducted to demonstrate the use of N-type redox-active radical polymer for totally organic polymer-based rechargeable battery applications. Aliphatic polymers, such as poly(2,2,6,6-tetramethylpiperidinyl-oxy-4- methacrylate) were used as cathode-active materials in a rechargeable battery. The densely populated and redox-isolated groups permit rapid and quantitative charge and discharge at a constant output voltage, contributing to the high capacity and high power rate performance of the battery. The study focused on the reversible and rapid one-electron redox reaction between galvinoxyl radicals and galvinolate anions, where the reduction of the neutral radical was regarded as an n-type redox reaction. N-type and rapid redox activity of poly(galvinoxylstyrene) was described, emphasizing on battery applications and demonstrating a new class of n-type redox-active polymers for a long term and charge-storage material.
