“…[75] Li 2 C 6 H 4 O 4 and Li 2 C 8 H 4 O 4 display very flat discharge plateaus at 1.4 and 0.8 V, respectively, which enables the use of a cheaper Al current collector. [94,111,112,[173][174][175][176][177][178][179][180][181] Although some advances in the cyclability and rate capability have been made, the capacities of the carboxylates still need to be enhanced to meet the requirements of battery systems with high energy density. It should be noted that only the trans versions of molecules with n = 2, 3, and 4 exhibited reversible reactivity towards Li.…”

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.

“…[6,8] This issue is commonly addressed inter alia by introducing ionic moieties, or by partial lithiation of the starting molecule. [6][7][8]14] Following these considerations, studies on carbonyl-based alternative anodes cover the whole range from lithium/sodium terephthalates [15][16][17][18][19][20][21][22] and benzenediacrylate [23] over naphthalene carboxylates [15,[24][25][26] to perylene carboxylates. [27][28][29][30] Although such an extension of the aromatic core to more than one phenyl ring leads to a decrease in specific capacity as a direct result of the increasing molecular mass, the amelioration of the π-electron delocalization positively affects the rate capability and cycling stability.…”

for tomorrow's society. [1][2][3] For this purpose, however, the battery technology itself must become sustainable as well. A great step forward toward this highly desirable goal would be the replacement of currently utilized inorganic electrode compounds, which commonly require energy-intensive synthesis methods and relatively rare metals, by eco-efficient organic lithium storage materials, ideally using biomass as precursors. [4] While this general concept has been proposed as early as the development of the first commercial lithium-based battery, [5] it was basically the work of Armand, Poizot, Tarascon, and co-workers, [6][7][8] reporting the reversible electrochemical activity of conjugated carbonyl functionalities, which triggered a continuously rising interest in studying macromolecular and polymeric compounds as lithium, and-due to their great versatility-sodium battery electrode materials. [9][10][11] In addition to their high availability, low cost, and environmental friendliness, organic active materials offer the distinguished advantage of tailorable lithium reaction potentials and capacities by carefully designing the molecular architecture. [9][10][11][12][13] In particular, the presence of planarly delocalized π-electrons, following the incorporation of phenyl groups in the units interconnecting the electrochemically active carbonyl functions, results in improved achievable capacities and Organic active materials are currently considered to be the most promising technology for the realization of fully sustainable secondary batteries. However, the understanding of the underlying reaction mechanisms is still at its beginning. In this paper, an in-depth investigation of tetra-lithium perylene-3,4,9,10-tetracarboxylate as a lithium-ion anode model compound is presented, which can be easily synthesized from commercially available 3,4,9,10-perylene-tetracarboxylic-dianhydride. The results reveal that the lithium uptake is limited to two lithium ions per molecule along a two-phase equilibrium potential within an operational voltage range down to 0.1 V. Below the corresponding potential plateau at 1.1 V the origin of the extra capacity is solely related to the presence of large amounts of conductive carbon. Based on these findings, optimized electrode composites with increased active material ratios of up to 95 wt% and a total active material mass loading of about 12.0 mg cm −2 , that is, remarkably augmented areal capacities (≈1.2 mAh cm −2 ), using percolating carbon nanotubes as electron conductor and environment-friendly, fluorine-free aqueous binders, are developed. In addition to the more than tenfold increase in areal capacity, these optimized electrode compositions show enhanced first cycle coulombic efficiencies, thus providing a great leap forward toward their commercial exploitation.
