Orthoquinone-Based Covalent Organic Frameworks with Ordered Channel Structures for Ultrahigh Performance Aqueous Zinc-Organic Batteries

Shibing Zheng et al.

Summary: Elaborate molecular design is crucial for improving the performance of rechargeable aqueous zinc-organic batteries. In this study, a novel orthoquinone-based covalent organic framework cathode with ordered channel structures (BT-PTO COF) was designed for an ultrahigh-performance aqueous zinc-organic battery. The ordered channel structure facilitated ion transfer and enabled the COF to follow a redox pseudocapacitance mechanism, resulting in a high reversible capacity and exceptional long-term cyclability. Additionally, a co-insertion mechanism involving Zn2+ and H+ was discovered for the first time, leading to ultra-fast kinetics and unprecedented specific power and energy density. This work presents a superior organic material for zinc batteries and offers a design concept for future high-performance organic cathodes.
