“…With the increase in energy demand and exploitation of renewable energy, solar, wind, and geothermal energy have been an increasingly important part of electricity supply. − However, the intrinsic discontinuity of the renewable resources limits direct utilization, making it impossible for energies to be incorporated into the current power grid. , Therefore, there is a great demand for developing a high-performance energy storage device. Since the 1990s, lithium-ion batteries (LIBs) have been developed as the most successful commercial rechargeable batteries due to their high energy density and excellent stability, which have brought about great changes to modern civilized society. − Nevertheless, the limited lithium resources and security issues of LIBs will restrict the application for the grid scale, and the increasing energy demand also calls for a new rechargeable system. , Dual-ion batteries (DIBs) show promising potential due to their low cost, fast kinetics, and environmental friendliness in recent years. − The research conducted on dual-ion batteries with an ionic liquid electrolyte (IL-DIBs) could be traced back to the 1990s. In 1994, Carlin et al first investigated the intercalation of various cations and anions into graphite, which came from the room-temperature molten electrolyte (ionic liquid), for instance, (DMPI)(AICI 4 ), (EMI)(BF 4 ), (EMI)(PF 6 ), etc.…”

Owing to the high theoretical capacity, sustainability, and flexible structure, organic electrode materials have been considered as a promising option for rechargeable batteries. Hence, an organic polymer molecule, poly(anthraquinonyl sulfide) (PAQS), is introduced as the anode material for a pure ionic liquid dual-ion battery (IL-DIB). Interestingly, the battery shows excellent rate performance; even at 120 C, the capacity could reach 41.9 mA h g −1 , and a maximum discharged capacity of 101.0 mA h g −1 is obtained at a rate of 10 C. Moreover, the properties of the battery that is charged at a high rate (40 C) and discharged at a low rate (2 C) are tested, revealing a considerable capacity (51.7 mA h g −1 ) and high energy efficiency (over 97%). In addition, scanning electron microscopy (SEM) and X-ray diffraction (XRD) characterization demonstrate that both the KS6 cathode and the PAQS anode remain in their original structure well after 300 cycles. Consequently, the KS6/PAQS IL-DIB shows great potential as a supercharged energy storage device for electric vehicles, mobile phones, and laptops.

“…Recently, a novel monomeric p‐type N‐substituted phenothiazine named lithium 4‐(10H‐phenothiazin‐10‐yl) benzoate (LiPHB) was reported as an efficient anionic host material for DIBs. [ 38 ] The reversible insertion/extraction of three kinds of anions, ClO 4 − , PF 6 − , and TFSI − , into/from LiPHB was investigated via a one‐electron reaction (Figure 2c). A specific capacity (SC) of 86 mAh g −1 and a retention rate of 72% after 500 cycles at 0.2 C (i.e., based on electron transfer from LiPHB) were obtained for an unoptimized Li−LiPHB DIB using LiClO 4 ‐based electrolyte in the potential range from 2.8 to 4.2 V. Besides, Zhang et al.…”

“…Besides this, more and more organic cathode materials have been investigated for anion intercalation in recent years. [ 18b,38 ] However, they are hampered by their low capacity, poor electronic conductivity, and limited cycle life. Thus, some strategies, such as coating and doping techniques, are proposed to improve the conductivity and reversibility of organic electrodes in DIBs.…”

Dual‐ion batteries (DIBs), based on the working mechanism involving the storage of cations and anions separately in the anode and cathode during the charging/discharging process, are of great interest beyond lithium‐ion batteries (LIBs) in high‐efficiency energy storage due to the merits of high working voltage, material availability, as well as low cost and excellent safety. Despite the progress achieved, the practical applications of DIBs are still hindered by negative issues, such as limited capacity and cyclic stability, which triggers the development of suitable electrode materials with highly reversible capacities, and corresponding electrolytes with high oxidative stability as well as sufficient reaction kinetics of active ions. Herein, in this article, a systematic and comprehensive review of fundamentals and recent advances in current DIBs with subcategories of cathode materials, anode materials, and electrolytes are presented. In particular, their energy storage mechanisms, as well as their respective features, are dissected. Furthermore, some strategies and perspectives are proposed for facilitating the further development of DIBs in the future.

“…Nitroxide based molecules and polymers are the best leading-contenders. [12][13][14] Nitroxide, p-type molecules based on other redox centers like aromatic amines, such as phenothia-zine and phenoxazine, have also gained popularity, [15,16] together with conjugates amines. [17,18] In recent years, several reports on a new p-type functional group, based on carbazole moieties, have also been published in the literature.…”

Herein the design, synthesis and electrochemical characterization of a set of insoluble molecular carbazole derivatives for electrochemical energy storage is proposed. Two strategies, based on the incorporation of an insoluble fragment or dimerization, were carried out to avoid the dissolution of the active material in the organic carbonate‐based liquid electrolyte solvent. The synthesized compounds enable the reversible anion intercalation from electrolyte, around 4.0 V vs. Li, through a p‐type mechanism, and showed an improvement in cycling stability, making them suitable for application as metal‐free positive electrodes for electrochemical energy storage systems. A first investigation to determine the impact of the electrolyte composition on the anion insertion mechanism and complemented with understanding of the redox mechanism was also carried out.
