Sodium 9,10-anthraquinone-2,6-disulfonate (Na 2 AQ26DS), with polyanionic character and two OÀNa ionic bonds, is found to be ah ighly stable organic cathode in Na-ion batteries, delivering capacities of approximately 120 mAh g À1 for 300 cycles (50 mA g À1 )a nd around 99 mAh g À1 for 1000 cycles (1 Ag À1 ). These resultsa re the best performance reported to date for small-molecule, anthraquinone-basedo rganic cathodes in Li-, Na-, or K-ionbatteries.The rapidly-growing demands for electric vehicles anda"smart grid" require large-scale applicationso fr echargeable batteries.[1] Therefore, electrode materials in batteries that are low in cost, free of resourcel imitations, and environmentally friendly are highly desirable . [2] At present,r echargeable Li-ion batteries are approaching the ceiling of their energy density. [3] Moreover, the limited resources of Li (0.0017 wt %f or Li in the Earth's crust) and of the rare metals contained in cathodes, such as Ni, Co, Mn, also impedet heir large-scale application. [4] Organic electrode materials with extremelyl ow costs have attractedm ore and more attention as promisingn ext-generation energy-storagem aterials. More importantly,o rganic electrodes have been found capable to store abundant, cheap, and large-radius metal ions, such as Na + ,K + ,a nd Mg 2 + . [5] There are two main concerns for organic electrode materials under consideration for practical application. One is that organic electrode materials usually suffer from poor electronic conductivity and thus give unsatisfactory rate performance. [6] However,this problem can be largely solved by careful technological modifications. The other is that small-molecule organic materials, particularly for high-capacity organic cathodes, [7] show significant solubility in organic liquid electrolytes, [8] ultimately leadingt ot he poor cycling stability of organicb atteries.

In this review, we summarize research efforts to realize Na-based organic materials for novel battery chemistries. Na is a more abundant element than Li, thereby contributing to less costly materials with limited to no geopolitical constraints while organic electrode materials harvested from biomass resources provide the possibility of achieving renewable battery components with low environmental impact during processing and recycling. Together, this can form the basis for truly sustainable electrochemical energy storage. We explore the efforts made on electrode materials of organic salts, primarily carbonyl compounds but also Schiff bases, unsaturated compounds, nitroxides and polymers. Moreover, sodiated carbonaceous materials derived from biomasses and waste products are surveyed. As a conclusion to the review, some shortcomings of the currently investigated materials are highlighted together with the major limitations for future development in this field. Finally, routes to move forward in this direction are suggested.

“…Guo et al have studied the solubility of anthraquinone (AQ) in CF3SO3Na-tetraglyme electrolytes at salt concentrations of 1-4 M and found continuously reduced AQ dissolution with the increase of electrolyte concentration. [26] In addition, the viscosity of the electrolyte increased by an order of magnitude as the concentration increased from 1 to 4 M (Figure 3a). Both decreased material solubility and increased electrolyte viscosity contributed to longer cycle life: the most concentrated electrolyte, 4 M CF3SO3Na in tetraglyme, afforded the highest reversible specific capacity and capacity retention (Figure 3b).…”

Organic electrode materials offer virtually infinite resource availability, cost advantages, and some of the highest specific energy for batteries to satisfy the demand for large-scale energy storage. Among the biggest challenges for the practical applications of batteries based on organic electrodes is the dissolution of organic active materials into the electrolyte, which leads to underwhelming cycling stability. This minireview provides an overview of electrolyte advancements to improve the stability of organic batteries. Research efforts on the control of solvent polarity, electrolyte mobility, and exploration of novel electrolyte systems are highlighted.
