Boosting High-Rate Zinc-Storage Performance by the Rational Design of Mn₂O₃ Nanoporous Architecture Cathode.

ABSTRACT: Manganese oxides are regarded as one of the most promising cathode materials in rechargeable aqueous Zn-ion batteries (ZIBs) because of the low price and high security. However, the practical application of Mn₂O₃ in ZIBs is still plagued by the low specific capacity and poor rate capability. Herein, highly crystalline Mn₂O₃ materials with interconnected mesostructures and controllable pore sizes are obtained via a ligand-assisted self-assembly process and used as high-performance electrode materials for reversible aqueous ZIBs. The coordination degree between Mn²⁺ and citric acid ligand plays a crucial role in the formation of the mesostructure, and the pore sizes can be easily tuned from 3.2 to 7.3 nm. Ascribed to the unique feature o
