Directing Mg-storage chemistry in organic polymers is crucial for achieving high-energy Mg batteries ^[Cang et al.]. Aqueous Mg-ion batteries (MIBs) have shown potential, but reliable anode materials are lacking ^[Cang et al.]. In this study, an avant-garde anode material, 3D-P(PDI-T), was designed and synthesized for MIBs ^[Cang et al.]. The increased aromatic structure of 3D-P(PDI-T) enhanced its structural stability and resulted in remarkable outcomes, including an extremely high rate capacity and significant reversible capacity in full cells ^[Cang et al.]. Covalent organic frameworks (COFs) were also explored as host materials for high-rate aqueous Mg2+ ion batteries ^[Zou et al.]. The Mg2+ ion diffusion kinetics in COFs were dominated by surface pseudocapacitive behavior, leading to favorable rate performance and durable cyclic stability ^[Zou et al.]. These findings provide insights into the development of organic materials and host materials for efficient charge-storage behavior in aqueous Mg-ion batteries ^[Cang et al.] ^[Zou et al.].
