Organic carbonyl electrode materials that have the advantages of high capacity, low cost and being environmentally friendly, are regarded as powerful candidates for next-generation stationary and redox flow rechargeable batteries (RFBs). However, low carbonyl utilization, poor electronic conductivity and undesired dissolution in electrolyte are urgent issues to be solved. Here, we summarize a molecular engineering approach for tuning the capacity, working potential, concentration of active species, kinetics, and stability of stationary and redox flow batteries, which well resolves the problems of organic carbonyl electrode materials. As an example, in stationary batteries, 9,10-anthraquinone (AQ) with two carbonyls delivers a capacity of 257 mAh g (2.27 V vs Li /Li), while increasing the number of carbonyls to four with the formation of 5,7,12,14-pentacenetetrone results in a higher capacity of 317 mAh g (2.60 V vs Li /Li). In RFBs, AQ, which is less soluble in aqueous electrolyte, reaches 1 M by grafting -SO H with the formation of 9,10-anthraquinone-2,7-disulphonic acid, resulting in a power density exceeding 0.6 W cm with long cycling life. Therefore, through regulating substituent groups, conjugated structures, Coulomb interactions, and the molecular weight, the electrochemical performance of carbonyl electrode materials can be rationally optimized. This review offers fundamental principles and insight into designing advanced carbonyl materials for the electrodes of next-generation rechargeable batteries.

“…In this view, the group of Poizot investigated the use of TMQ 68 (Scheme 17) as redox-active molecule for its expected two-electron reaction which leads to an expected specific capacity of 235 mAh · g À 1 , using the commercially available LiTFSI/PEO-based solid polymer electrolyte (O/Li molar ratio = 25) at 100°C. [53] A reversible capacity of about 80 % of the theoretical value (190 mAh · g À 1 ) could be delivered after 20 cycles at a rate of 1 Li/30 min with remarkable power performance. Besides, the diffusion of TMQ 68 through the electrolyte film could not be fully prevented as attested by the colour of the electrolyte, which, had turned to the typical orange colour of TMQ 68 without apparent degradation.…”

The constant growth in the global energy demand together with the increasing awareness of clean and sustainable development has strongly pushed scientists to search for metal‐free, low‐cost, environmentally friendly functional energy‐storage systems (ESSs). Among the reported organic electrode materials, carbonyl‐based π‐conjugated compounds show excellent rate capabilities and cycling stabilities and are powerful candidates for the next generation of rechargeable lithium‐ion batteries (LIBs). Benefiting from the molecular structure versatility and design feasibility, the electrochemical properties of organic and polymeric materials can be easily tuned. This Review summarizes recent efforts in the search for carbonyl‐based π‐conjugated electrode materials in LIBs with a focus on the synthetic strategies developed to improve their electrochemical performance. The use of these materials in flexible, all‐organic LIBs is highlighted as a unique direction towards widespread applications of LIBs.

“…However, the major drawback in the application of small quinonide molecules as active electrode material is their solubility in common organic electrolytes, which leads to a rapid capacity decrease within the first charge/discharge cycles. Special battery setups with crystalline electrodes or quasi‐solid electrolytes enable battery systems with small quinonide molecules, but their setup end electrolytes are very complex . A simple and promising approach to overcome these decisive disadvantages is the incorporation of the redox‐active unit into a polymeric backbone, resulting in an insoluble, but swellable material that remains electro‐active in the solid state …”

Redox‐active polymers draw significant attention as active material in secondary batteries during the last decade. A new anthraquinone‐based redox‐active monomer was designed, which electrochemical behavior was tailored by mono‐modification of one keto group. The monomer exhibits two one‐electron redox reactions and has a low molar mass, resulting in a high theoretical capacity of 207 mAh/g. The polymerization of the monomer was optimized by variation of solvent and initiator. Moreover, the electrochemical behavior was studied using cyclic voltammetry and the polymer was used as active material in a composite electrode in lithium organic batteries. The polymer reveals a cell potential of 2.3 V and a promising capacity of 137 mAh/g. During the first 100 cycles, the capacity drops to 85% of the initial value. The influence of the charging speed on the charging/discharging properties of the batteries was further investigated. © 2015 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.
