Coupling abundant active sites and an ultra-short ion diffusion path: R-VO₂/carbon nanotube composite microspheres boosted the performance of aqueous ammonium-ion batteries.

ABSTRACT: Ammonium (NH₄ ⁺) ions as charge carriers have exhibited tremendous potential in aqueous batteries because of their abundant resources, ultrafast reaction kinetics, and negligible dendrite risks. However, the choices of cathode materials have resulted in relatively low capacities in aqueous ammonium ion batteries (AAIBs). Herein, double tunnel NH₄ ⁺ ion insertion behavior with hydrogen bond building-breaking in rutile-phase VO₂ (R-VO₂) microspheres was revealed for the first time, and the capacity contribution was confirmed to be dominated by surface-control according to kinetic analysis and density functional theory (DFT) calculations.
