“…Disodium rhodizonate (Na 2 C 6 O 6 ), which is an analogue of the Li version (dilithium rhodizonate), [ 254 ] was reported as a Na organic cathode by Chihara et al [ 255 ] Na 2 C 6 O 6 has a layered structure and exhibits n-type properties with conjugated carbonyl groups. They showed that Na 2 C 6 O 6 cathode exhibits a reversible capacity of 170 mA h g −1 with a good cycle performance at an average working voltage of 2.18 V vs Na + /Na; however, the origin of the much lower specifi c capacity compared with its Li analogue remains unclear.…”

Grid‐scale energy storage systems (ESSs) that can connect to sustainable energy resources have received great attention in an effort to satisfy ever‐growing energy demands. Although recent advances in Li‐ion battery (LIB) technology have increased the energy density to a level applicable to grid‐scale ESSs, the high cost of Li and transition metals have led to a search for lower‐cost battery system alternatives. Based on the abundance and accessibility of Na and its similar electrochemistry to the well‐established LIB technology, Na‐ion batteries (NIBs) have attracted significant attention as an ideal candidate for grid‐scale ESSs. Since research on NIB chemistry resurged in 2010, various positive and negative electrode materials have been synthesized and evaluated for NIBs. Nonetheless, studies on NIB chemistry are still in their infancy compared with LIB technology, and further improvements are required in terms of energy, power density, and electrochemical stability for commercialization. Most recent progress on electrode materials for NIBs, including the discovery of new electrode materials and their Na storage mechanisms, is briefly reviewed. In addition, efforts to enhance the electrochemical properties of NIB electrode materials as well as the challenges and perspectives involving these materials are discussed.

“…One example of an OSIB cathode compound is disodium rhodizonate 10 (Figure 8). This displayed good results even without conductive additive, which is rare for an organic electrode material [33]. At a potential of 2.18 V, the compound shows a good performance with a capacity of 170 mAh·g −1 .…”

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.

“…In addition, the preparation processes of such organic materials can be less energy demanding compared with those of inorganic materials because the latter are usually processed at higher temperatures than the former. The combination of organic materials that contain no scarce metal resources and a sodium-based electrolyte solution will realize a totally “rare metal-free” battery; however, the behaviors of such organic materials as the active materials of sodium battery systems are less well-known except for a few preceding examples181920. Previously, we reported the battery performance of a series of redox active organic materials in lithium electrolyte systems21222324252627.…”

Using sodium, instead of lithium, in rechargeable batteries is a way to circumvent the lithium's resource problem. The challenge is to find an electrode material that can reversibly undergo redox reactions in a sodium-electrolyte at the desired electrochemical potential. We proved that indigo carmine (IC, 5,5′-indigodisulfonic acid sodium salt) can work as a positive-electrode material in not only a lithium-, but also a sodium-electrolyte. The discharge capacity of the IC-electrode was ~100 mAh g−1 with a good cycle stability in either the Na or Li electrolyte, in which the average voltage was 1.8 V vs. Na+/Na and 2.2 V vs. Li+/Li, respectively. Two Na ions per IC are stored in the electrode during the discharge, testifying to the two-electron redox reaction. An X-ray diffraction analysis revealed a layer structure for the IC powder and the DFT calculation suggested the formation of a band-like structure in the crystal.
