Poly(TEMPO)/Zinc Hybrid‐Flow Battery: A Novel, “Green,” High Voltage, and Safe Energy Storage System

Abstract

The combination of a polymer-based 2,2,6,6-tetramethylpiperidinyl-N-oxyl (TEMPO) catholyte and a zinc anode, together with a cost-efficient size-exclusion membrane, builds a new type of semi-organic, "green," hybrid-flow battery, which features a high potential range of up to 2 V, high efficiencies, and a long life time.
