Self-charging zinc batteries that combine energy harvesting technology with are candidates for reliable self-charging power systems. However, the lack of rational materials design results in unsatisfactory performance. Here, a covalent organic framework containing pyrene-4,5,9,10-tetraone groups (COF-PTO) is reported as cathode material aqueous batteries. The ordered channel structure COF-PTO provides excellent capacity retention 98% after 18 000 cycles at 10 A g

Abstract Rechargeable aqueous calcium‐ion batteries (CIBs) are promising for reliable large‐scale energy storage. However, they face significant challenges, primarily stemming from suboptimal anodes, resulting in unfavorable voltage profiles, limited capacity, and diminished durability, all of which hinder the development CIBs. Here, a covalent organic framework (PTHAT‐COF) featuring repeated pyrazine pyridinamine units, employed as anode material CIBs, is introduced. This innovative...
