δ-MnO₂ nanoflower/graphite cathode for rechargeable aqueous zinc ion batteries.

ABSTRACT: Manganese oxide (MnO₂) is one of the most promising intercalation cathode materials for zinc ion batteries (ZIBs). Specifically, a layered type delta manganese dioxide (δ-MnO₂) allows reversible insertion/extraction of Zn²⁺ ions and exhibits high storage capacity of Zn²⁺ ions. However, a poor conductivity of δ-MnO₂, as well as other crystallographic forms, limits its potential applications. This study focuses on δ-MnO₂ with nanoflower structure supported on graphite flake, namely MNG, for use as an intercalation host material of rechargeable aqueous ZIBs. Pristine δ-MnO₂ nanoflowers and MNG were synthesized and examined using X-ray diffraction, electron spectroscopy, and electrochemical techniques. Also, performan
