“…Conductive polymers usually show high electronic conductivity due to their long π‐electron conjugated system, which will contribute to their fast redox kinetics [51] . Among various conductive polymers, PANI and polypyrrole (PPy) have been used to serve as the electrode materials of aqueous ZIBs (Figure 6).…”

Organic electroactive compounds are attractive to serve as the cathode materials of aqueous zinc‐ion batteries (ZIBs) because of their resource renewability, environmentally friendliness and structural diversity. Up to now, various organic electrode materials have been developed and different redox mechanisms are observed in aqueous Zn/organic battery systems. In this Minireview, we present the recent developments in the energy storage mechanisms and design of the organic electrode materials of aqueous ZIBs, including carbonyl compounds, imine compounds, conductive polymers, nitronyl nitroxides, organosulfur polymers and triphenylamine derivatives. Furthermore, we highlight the design strategies to improve their electrochemical performance in the aspects of specific capacity, output voltage, cycle life and rate capability. Finally, we discuss the challenges and future perspectives of aqueous Zn/organic batteries.

“…To further understand ion storage process in the H 2 TPP and H 2 TCPP positive electrodes, electrochemical kinetic analyses were further investigated by recording the relationship of peak current (i) and scan rates (v) in CV curves (Figure 2a,d). At different scan rates, the relationship between the measured current and sweep rates in CV curves can be written as follows: [28] i a v = × b…”

electric vehicles, and more. [4,5] Among these rechargeable battery technologies, sodium, [6][7][8] magnesium, [9,10] zinc, [11,12] calcium, [13] and aluminum [14][15][16] ion batteries have drawn unique attention as the candidates of next-generation batteries. In particular, rechargeable aluminum-ion batteries (AIBs) hold impressive advantages, such as wide temperature range, high safety, and low cost. [17][18][19] However, there is still plenty of room for improving the energy density and long-term life cycle of the positive electrode materials in AIBs. Hence, it is significant to design appropriate positive electrode materials to promote the performance of current AIBs. Recently, extensive efforts have been devoted to the development of organic materials owing to their unique structural features, such as chemical diversity and structure designability, which allows for achieving suitable active molecules for targeted electrodes. [20][21][22] In addition, weak intermolecular forces between active ions in the electrolyte and host materials are beneficial to the reversibility and kinetics of electrochemical reactions. [23,24] Moreover, molecular engineering could be employed to manipulate the voltage plateaus, electrical conductivity, and structural stability of organic materials, which enables the organic molecules to serve as a promising candidate material for next-generation electrode materials.At present, organic electrode materials reported in the AIBs mainly refer to the oxygen or nitrogen active sites in the compounds with carbonyl (CO) or in the nitrogen-containing compounds (CN), due to their structural diversity and chemical stability. In addition, this type of organic material is mainly based on coordination chemical reactions. [21,22,[25][26][27][28] Specifically, many studies on the compounds with carbonyl functional group have been reported. For example, Stoddart [25] and his colleagues synthesized a redox-active phenanthraquinone (PQ) macrocyclic compound, and the corresponding insertion mechanism between aluminum complex ions and conjugated carbonyl materials has been studied. Subsequently, they have improved specific capacity, electrical conductivity, and areal loading via blending PQ with graphite flakes. In the study from Lu and coworkers, [26] a polyimide (PI)/metal-organic framework (MOFs) hybrid material was reported. Also, Wang and coworkers [22] employed PI/CNT as the positive material in Al-organic battery. In the Aluminum-ion batteries (AIBs) attract interest for their promising features of superior safety and long-life energy storage. Organic materials with engineered active groups are considered promising for promoting energy storage capabilities. However, the corresponding energy density (both voltage plateau and sufficient active sites required) and stability are still unexpectedly poor. To address these challenges, here π-conjugated organic porphyrin molecules, that is, 5,10,15,20-tetraphenylporphyrin (H 2 TPP) and 5,10,15,20-tetrakis(4carboxyphenyl) porphyrin (H 2 TCPP), are selec...
