Ion-Mediated Carbon Microdomain Engineering Boosting Enhanced Plateau Capacity of Carbon Anode under High Rate Towards High-Performance Sodium Dual-Ion Batteries

Abstract Sodium-based dual-ion batteries (SDIBs) have been attracting increasing attention in recent years owing to their low cost, environmental benignancy, and high operating voltage. However, the sluggish ion kinetics of conventional carbon anodes that cannot match the fast capacitive anion intercalation behavior of graphite cathodes constraints on improving power density of SDIBs. Herein, we present an ingenious carbon microdomain engineering strategy to fabricate high-performance carbon anode with ion-mediated high-activity nitrogen species and molecular-scale closed-pore architectures. Experimental characterizations and theoretical investigations demonstrate that Zn 2+ -mediated structural engineering…
