“…According to the different types of intake/ release counter-ions, the redox reaction of organic electrode materials can be classified into three types (n-, p-and bipolartype). [12,13] Since Hideki Shirakawa discovered conductive polymers (CPs) in 1990, [14] p-type materials, typically polypyrrole (PPy), polythiophene (PTh), carbazole and 2,2,6,6-tetramethyl piperidinyloxyl (TEMPO) [15][16][17][18][19] have been continuously used as organic electrode materials. This p-type doping greatly improves its conductivity and working potential, but the low specific capacity of p-type materials limits their further development and application.…”

Dual‐ion batteries based on organic electrodes show great potential to break through the bottlenecks existed in conventional LIBs due to their high specific capacity, lifted working voltage, and environmental benignity. Herein, two innovative viologen‐based bipolar copolymers poly(viologen‐pyrene‐4,5,9,10‐tetrone dichloride) (PVPTOCl2) and poly(viologen‐anthraquinone dichloride) (PVAQCl2) were synthesized and applied as high performance cathodes for lithium‐dual‐ion battery. Bearing the dual‐ion storage capability of viologen and carbonyls, as well as the conjugated structure of pyrene‐4,5,9,10‐tetrone, the synthesized copolymers show remarkable electrochemical performances for LIBs. Compared to PVAQCl2, PVPTOCl2 shows superior electrochemical performance with high initial specific capacity (235.0 mAh g‐1 at 200 mA g‐1), excellent rate performance (150.3 mAh g‐1 at 5 A g‐1) and outstanding cycling stability (a reversible capacity of 197.5 mAh g‐1 at a current density of 1 A g‐1 and a low capacity loss per cycle of 0.11‰ during 3000 cycles). Moreover, the charge storage mechanism was systematically investigated by ex‐situ FT‐IR, ex‐situ XPS and DFT calculations. The results clearly reveal the structure‐property relationship of the bipolar‐molecules, providing a new platform to develop efficient bipolar materials for dual‐ion batteries.

“…Several methods have been implemented to functionalize conductive surfaces; however, electropolymerization is the oldest, quickest, and most convenient technique. It has many advantages over conventional polymerization techniques, including the ability to control the thickness and properties of the polymer film, as well as single-step synthetic procedures . This technique is especially suitable for the preparation of conductive polymers, including poly(3,4-ethylenedioxythiophene), polyaniline, polypyrrol, and polythiophene, as well as for the synthesis of transition metal complex materials (e.g., Prussian blue) .…”

Electropolymerization is an important technique for surface functionalization, owing to its convenient and controlled synthetic pathways. The in situ synthesis of metallosupramolecular polymers (MSPs) utilizing coordination-driven metal ions and coordinating ligands as well as studying their potential applications using electropolymerization have been less explored. Herein, we demonstrated the formation of MSPs on a preterpyridinefunctionalized indium tin oxide (ITO) glass substrate by using Fe(III) ions and 4′,4⁗-(1,4-phenylene)-bis(2,2′:6′,2″-terpyridine) ligand. By providing an anodic potential, polymer growth occurred due to the strong coordination between the reduced metal ions (Fe(II)) and the bis-terpyridine ligand. The formation of the polymer was evident from the growth of the corresponding peaks in the cyclic voltammogram and UV−vis spectral profile. The surface morphology was characterized by using atomic force microscopy (AFM). The electrochromic (EC) properties of the electropolymerized MSP (EP-MSP) were studied by utilizing the metal-to-ligand charge-transfer color band of the redox-active Fe(II)-(terpyridine) 2 unit present in the MSP backbone. It was observed that the film exhibited an optical switching coloring time of 2.1 and 5.7 s for bleaching, a transmittance change of 54%, and a coloration efficiency of 142.6 cm 2 C −1 .

“…19,20 To date, organic materials have been emerging as a possible substitution for inorganic electrode materials due to their intrinsic advantages of low cost and density, earth-abundant, and tunable chemical properties. 21,22 Many kinds of organic materials have been explored including carbonyl-based compounds and polymers for Li-ion batteries, 23,24 organosulfur compounds and polymers for Li-S batteries, 25 and radical-based polymers for both Li-ion and Li-S batteries. 26 Among the well-developed organic electrode materials, small organic molecules are widely used, but usually show poor cycling performance due to the dissolution of active materials.…”
