“…The in situ Fourier transform infrared spectra (FT‐IR) are shown in Figure 3, where the sharp peaks observed at 1676.03 and 1569.61 cm −1 correspond to the stretching vibrations of the C=O and C=C bonds, respectively, while the weak peak at 1414.27 cm −1 corresponds to the stretching of the S‐disubstituted aromatic ring [10] . A comparison of the two figures shows that the intensity of the peak at 1414.27 is significantly weakened after the strong oxidation treatment.…”

“…The in situ Fourier transform infrared spectra (FT-IR) are shown in Figure 3, where the sharp peaks observed at 1676.03 and 1569.61 cm À 1 correspond to the stretching vibrations of the C=O and C=C bonds, respectively, while the weak peak at ChemistrySelect 1414.27 cm À 1 corresponds to the stretching of the S-disubstituted aromatic ring. [10] A comparison of the two figures shows that the intensity of the peak at 1414.27 is significantly weakened after the strong oxidation treatment. The reason is that the electron attraction of the S atom to the benzene ring is reduced, resulting in a lower degree of deformation of the Sdisubstituted aromatic ring and reducing the intensity of its peak.…”

“…[3] The solubility of the active material in the electrolyte can be reduced owing to the stable structure of the redox-active polymer electrode material. [4] Poly(anthraquinonyl sulfide) (PAQS) is an anthraquinone (AQ) polymer with a stable backbone and highly electroactive functional groups for polymerization, which exhibits inherently faster kinetics than inorganic intercalation cathodes. [5] Therefore, it has the poten-tial to be a candidate material for high-power negative electrodes.…”

Organic electrode materials have received much attention in recent years, but their solubility of organic affects the capacity of the battery and the cycling performance. The solubility can be effectively reduced by polymerization, which can improve the stability of the material, but the capacity of organic polymer materials generally decreases with an increase in molar mass. In this study, poly(anthraquinonyl sulfide) (PAQS) is strongly oxidized, and its morphological characteristics and active sites are found to change without affecting its solubility, leading to enhanced the battery capacity and stability performance. The experimental results show that PAQS is converted into micro-sized spherical particles after being treated with H 2 SO 4 solution.This process changes the sulfone group structure of PAQS and increases its active site S=O bond. Calculations show that the adsorption energy of the S=O active site is more stable than that of the original C=O active site, making it easier for the S=O group to adsorb cations. At the same time, the conductivity of PAQS increases after the treatment. The experimental results show that the capacity of the battery is 128.3 mAhg À 1 at a current rate of 2 C when the strongly oxidized PAQS is used as the negative electrode, while the initial capacity was only 84.3 mAhg À 1 under the same test conditions before the treatment.

“…Zhu et al also use PAQS as anode material, natural graphite as cathode, and N-propyl-N-methylpyrrolidinium (trifluoromethanesulfonyl)imide (Pyr 13 TFSI) as ionic liquid electrolyte to assemble a DIBs. [137] Figure 11a shows the schematic of this DIB. Here, the use of glass fiber separators can greatly influence the performance of battery.…”

Organic materials are widely used in various energy storage devices due to their renewable, environmental friendliness and adjustable structure. Dual‐ion batteries (DIBs), which use organic materials as the electrodes, are an attractive alternative to conventional lithium‐ion batteries for sustainable energy storage devices owing to the advantages of low cost, environmental friendliness, and high operating voltage. To date, various organic electrode materials have been applied in DIBs. In this review, we present the development of DIBs with a following brief introduction of characteristics and mechanisms of organic materials. The latest progress in the application of organic materials as anode and cathode materials for DIBs is mainly reviewed. Finally, we also discussed the challenges and prospects of organic electrode materials for DIBs.

“…[12] Because polymers are chemically controllable and highly porous as well as have long chains, they are introduced as SEI films coated on Li foils. [13] Brunklaus et al designed viscoelastic polyborosiloxanes as a coating layer on a lithium metal anode with various degrees of cross-linking. [14] Wang et al synthesized poly-dioxolane as an elastic artificial SEI film.…”

Lithium‐based batteries (LBBs) have virtually dominated the energy storage market for electronic products and electric vehicles. In these batteries, the critical roles of polymers cannot be ignored. In this article, state‐of‐the‐art developments and perspectives for improving the safety and stability of LBBs using polymers are summarized. These materials are particularly used as separator decorations, solid‐state electrolytes, binders, and fire retardants. Polymers exhibit excellent performance as binders for Si anodes because of their long chains and high adhesion ability. This review focuses on the application of polymers to Li–S batteries based on their fundamental electrochemistry and the challenges arising from the dissolution of polysulfides. In addition, the dendrite growth inhibition ability and mechanism of polymeric artificial solid electrolyte interphase film and solid‐state electrolytes are described. The performance of polymer as fire retardant and the mechanism for solid‐state polymer electrolytes are elaborated. Finally, the perspectives on the potential of polymers for LBBs and energy storage because of their outstanding plasticity and chemical controllability are presented.
