Exploring Bio-inspired Quinone-Based Organic Redox Flow Batteries: A Combined Experimental and Computational Study

Abstract

Yu and colleagues take a combined experimental and theoretical approach to investigating quinone-based organic redox flow batteries and establish a useful guideline for designing organic electroactive materials in stationary energystorage applications.

The Promise of Environmentally Benign Redox Flow Batteries by Molecular Engineering

“…[9] Further research reveals that the power performance can be boosted by optimizing electrolyte conditions and battery design (for example,c hannel configuration and the porous carbon current collector). [11] All these features promise an ext-generation energy storage system with al ow carbon footprint, and it is promising to achieve afuture green battery life cycle (Figure 2b). This work provides auseful guideline to develop environmentally benign, sustainable energy storage systems via function-oriented organic synthesis and structural tuning.…”

Iron‐Dicyano Dichloro Quinone Primary Battery

“…During the last two decades, the European Union adopted several regulations to ban or reduce hazardous metals that can be present in the batteries . Identifying bio‐inspired and eco‐friendly materials with single/multiple use, environmentally safe, cost effective and with no or less disposal waste is the biggest challenge. To meet these requirements, efforts are underway to reduce the cost by substituting with alternative eco‐friendly materials.…”

“…To meet these requirements, efforts are underway to reduce the cost by substituting with alternative eco‐friendly materials. In the context of environmental benign battery, quinone based organic materials were explored as low carbon foot print materials in Na, Li and organic flow batteries The research on designing the new organic materials for better electrochemical performance is continuously growing of late.…”

“…(Fe‐DDQ) primary battery as an alternative to expensive primary batteries that are in use. The quinone based organic molecules are potentially low cost and easily preparable . In Fe‐DDQ primary battery, DDQ acts as an oxidant (cathode).…”

Membrane‐Free Zn/MnO2 Flow Battery for Large‐Scale Energy Storage

“…Different from solid‐state active materials as secondary battery electrodes, redox flow battery has a prominent ability to tailor the energy capacity independently from the power output . Generally, liquid electrolyte and electroactive materials are stored externally, and the role of electrode is merely to provide the electrochemically active surface for redox reaction to take place, such as vanadium redox battery, zinc/bromine battery, zinc/iodine flow battery, lead acid, and alkaline quinone flow battery .…”
