Asolid dispersion redox flow battery is a type ofredox flow battery using dispersed solid active materials as theenergy storage media. The solid suspensions are stored in energy storage tanks and pumped through electrochemical cells while charging or discharging. In comparison with a conventionalredox flow battery where active species are dissolved in aqueous or organicelectrolyte, the active materials in a solid dispersion redox flow battery maintain the solid form and are suspended in theelectrolyte.[1] Further development expanded the applicable active materials.[2] The solid active materials, especially with active materials fromlithium-ion battery, can help the suspensions achieve much higherenergy densities than conventionalredox flow batteries. This concept is similar to semi-solid flow batteries in which slurries of active materials accompanied by conductive carbon additives to facilitate electrons conducting are stored in energy storage tanks and pumped through the electrochemical reaction cells.[3] Based upon this technique, an analytical method was developed to measure the electrochemical performance of lithium-ion battery active materials, nameddispersed particle resistance (DPR).[4][5][6]
