“…3c), which is almost double the initial discharge capacity of 40 mAg -1 observed for the full cell fabricated with NTCDA based polyimide as anode. 36 A gradual decrease in the specific capacity upon cycling was observed (Fig. 3d), which could be improved with further optimization of the electrode loading and other cell parameters.…”

Developing new approaches to improve the performance of organic electrodes for rechargeable sodium batteries is important. Here we report studies on N,Nʹ-diamino-3,4,9,10 perylenetetracarboxylic polyimide (PI) as a novel cathode for sodium battery and demonstrate an all-organic sodium ion battery using this polyimide as cathode and disodium terephthalate (NaTP) (pre-sodiated) as anode. The synthesised PI exhibits excellent electrochemical properties, when studied as cathode for sodium batteries, with a reversible capacity of 126 mAhg -1 along with good capacity retention and rate capability, in the voltage range of 1.5 to 3.5 V vs. Na + /Na. The all-organic sodium ion full cell delivered an initial capacity of 73 mAhg -1 , with an average cell voltage of 1.35 V. The attractive electrochemical performance combined with the design flexibility of PTCDA based PI material, offer new possibilities for the development of efficient all-organic sodium batteries.

“…Meanwhile, rechargeable Mg batteries have been regarded as safer and more reliable systems than LIBs. [208] Interestingly, this system could render a stable capacity of 71 mAh g -1 and an energy density of 80 Wh kg -1 in 5 M LiNO 3 solution, which far exceed the values of all-inorganic electrode-based ARLBs. From this point of view, organic crystals could be potential electrode materials for Mg 2+ storage because interactions in organic crystals are usually through weak intermolecular forces.…”

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.

From the viewpoint of the cost and safety, aqueous sodium-ion batteries are attractive candidate for large-scale energy storage. Although the operating voltage range of the aqueous battery is theoretically limited to 1.23 V by the electrochemical decomposition of water, the voltage restriction is a little bit eased in real aqueous battery system by the charge/discharge overvoltage. Effect of the concentrated electrolyte on the operation voltage was studied in aqueous Na-ion battery with Na 2 MnFe(CN) 6 hexacyanoferrates cathode and NaTi 2 (PO 4 ) 3 NASICON-type anode, in order to increase the discharge voltage. According to the cyclic voltammetry, the electrochemical window of diluted 1 mol kg −1 NaClO 4 aqueous electrolyte is only 1.9 V, whereas the corresponding electrochemical window of concentrated 17 mol kg −1 NaClO 4 aqueous electrolyte is widen to 2.8 V. This wide electrochemical window of the concentrated aqueous electrolyte allows the Na 2 MnFe(CN) 6 //NaTi 2 (PO 4 ) 3 aqueous sodium-ion system to work reversibly. By contrast, the framework of Na 2 MnFe(CN) 6 cathode was destroyed by the hydroxide anion generated in diluted 1 mol kg −1 electrolyte.
