“…Organic materials are also considered to be more suitable as Mg battery cathodes as it breaks the obstacle of inorganic Mg 2+ ‐intercalation crystal lattice. However, compared with the reports on organic Li + ‐ and Na + ‐storage materials, the investigations on organic Mg 2+ ‐storage materials are disproportionately rare [11–18] . Because of the relatively high charge density of Mg 2+ cations, the promising Mg 2+ ‐storage organic materials would have different structure features with Li + ‐ and Na + ‐storage materials.…”

“…However, compared with the reports on organic Li +and Na + -storage materials, the investigations on organic Mg 2 + -storage materials are disproportionately rare. [11][12][13][14][15][16][17][18] Because of the relatively high charge density of Mg 2 + cations, the promising Mg 2 + -storage organic materials would have different structure features with Li + -and Na + -storage materials. Therefore, it is not appropriate to use the principles of Li + -and Na + -storage properties for the design of Mg 2 + -storage organic materials, and studies on the Mg 2 + -storage performance are of great significance for exploring high-performance organic Mg battery cathodes.…”

Inorganic cathodes of rechargeable Mg batteries suffer from limited selections, while organic materials provide more options. Herein, three conjugated dianhydrides, pyromellitic dianhydride, 1,4,5,8-naphthalenetetracarboxylic dianhydride and 3,4,9,10-perylenetetracarboxylic dianhydride are comparatively investigated to elucidate the effects of conjugated structure on the Mg 2 + storage performances. It is observed that the reversible Mg 2 + storage capacity is more dependent on the conjugated structure than carbonyl numbers. Ex-situ mechanism study illustrates that the extended conjugated structure delocalizes the electron density, hence enhancing carbonyl enolization and increasing the Mg 2 + storage capacity. Furthermore, the largely conjugated structure buffers the charge density change during repeated magnesiation/demagnesiation resulting in better cyclability. Prominently, 3,4,9,10-perylenetetracarboxylic dianhydride shows a high Mg 2 + storage capacity (160 mAh g À 1 ) and a good cycling stability (80 % capacity retention after 100 cycles) with the largest conjugated structure. This work provides a low-cost cathode for rechargeable Mg batteries that can be utilized for designing high-performance organic Mg battery cathodes.

Owing to their extraordinary properties of π-conjugated polymers (π-CPs), such as light weight, structural versatility, ease of synthesis and environmentally friendly nature, they have attracted considerable attention as electrode material for metal-ion batteries (MIBs) and supercapacitors (SCPs). Recently, researchers have focused on developing nanostructured π-CPs and their composites with metal oxides and carbon-based materials to enhance the energy density and capacitive performance of MIBs and SCPs. Also, the researchers recently demonstrated various novel strategies to combine high electrical conductivity and high redox activity of different π-CPs. To reflect this fact, the present review investigates the current advancements in the synthesis of nanostructured π-CPs and their composites. Further, this review explores the recent development in different methods for the fabrication and design of π-CPs electrodes for MIBs and SCPs. In review, finally, the future prospects and challenges of π-CPs as an electrode materials for strategies for MIBs and SCPs are also presented.
