“…The molecular electrostatic potential (MESP) values on the van der Waals surface of PDABQ can be graphically illustrated with a color scale, where the positively charged regions are represented in red and the negatively charged regions in blue, providing a visual representation of the electrostatic characteristics of the molecule. According to the MESP mapping, the sites (CO) with the most negative MESP values have the lowest electrostatic potential, thus rendering the CO groups as the optimal sites for lithium storage with high redox activity . Based on the aforementioned results (Figure e), a proposed lithium storage mechanism for the PDABQ cathode has been developed.…”

Organic electrode materials show promise for application in rechargeable batteries due to their potential for high capacity, tunable structures, flexibility, and sustainability. However, the serious dissolution problem in organic electrolytes and the inferior intrinsic conductivity of organic electrode materials limit their performance and practical applications in LIBs. Herein, a novel carbonyl-enriched polymer (PDABQ) was designed and synthesized from tetraaminobenzoquinone (TABQ) and chloranil (TCBQ). The integration of low molecular weight −NH− with quinone units can effectively improve the theoretical specific capacity and extend the conjugated structure. Meanwhile, the hydrogen bonds between C�O and −NH− and intermolecular π−π interactions further enhance the solvent resistance and the charge transfer rate of the PDABQ cathode. Therefore, the PDABQ cathode shows long-term cycling stability (88.8% capacity retention after 1000 cycles at 2 A g −1 ), high reversible specific capacity (234.2 mA h g −1 at 0.1 A g −1 ), and outstanding rate performance (161.2 mA h g −1 at 2 A g −1 , 75.9% capacity retention versus 0.1 A g −1 ). This work offers an effective and convenient molecular structure design strategy for highperformance organic carbonyl polymer cathode materials.

Despite the prevailing dominance of lithium‐ion batteries in consumer electronics and electric vehicle markets, the growing apprehension over lithium availability has ignited a quest for alternative high‐energy‐density electrochemical energy storage systems. Rechargeable batteries featuring calcium (Ca) metal as negative electrodes (anodes) present compelling prospects, promising notable advantages in energy density, cost‐effectiveness, and safety. However, unlocking the full potential of rechargeable Ca metal batteries particularly hinges upon the strategic identification or design of high‐energy‐density positive electrode (cathode) materials. This imperative task demands expeditious synthetic routes tailored for their meticulous design. In this Perspective, we mainly highlight the development in the cathode materials for calcium batteries and accentuate the unparalleled promise of solid‐state metathesis routes in designing a diverse array of high‐performance electrode materials.
