Abstract

Charging and discharging reactions of lithium metal oxides in lithium-ion batteries are accelerated by adding a catalytic amount of redox-active polymer, poly(dimethylfluoflavin-substituted norbornene). The potential difference between the polymer (E1/2 = 3.5 and 4.1V vs. Li/Li+) and metal oxides induce redox mediation reactions. Their heterogeneous charge-transfer processes are analyzed to estimate the acceleration effects of mediation.
