Covalent Organic Framework-based Microspheres as Anode Material for Rechargeable Sodium Batteries

Abstract

Covalent organic frameworks (COFs) promise several benefits as material in terms of gas adsorption, optoelectronic devices etc. However, energy storage ability of COFs has not been well studied, especially in sodium batteries. In this report, for the first time, a covalent organic framework (COF), TFPB-TAPT COF is used as an anode with high capacity in sodium batteries. The TFPB-TAPT COF exhibits an initial reversible capacity of 246 mA h g–1 and a capacity of 125 mA h g–1 is retained after 500 cycles. The TFPB-TAPT COF further exhibits Na+ ion storage capability at different current rates. The Na+ ions storage viability of TFPB-TAPT COF arises mainly because of its open ordered nanoporous framework, which provides reversible accommodation for ions. This work opens up a promising new approach for further utilization of COFs as an electrode materials in rechargeable sodium batteries.
