TL;DR: The intercalation mechanism of zinc ions into 2 × 2 tunnels of an α-MnO2 cathode for rechargeable zinc batteries was revealed and produces buserite, a layered compound with an interlayer spacing of 11 Å as a discharge product.

TL;DR: The reaction mechanism of α-MnO2 having 2×2 tunnel structure with zinc ions in a zinc rechargeable battery, employing an aqueous zinc sulfate electrolyte, was investigated by in situ monitoring structural changes and water chemistry alterations during the reaction.

TL;DR: The intercalation mechanism of zinc ions into α-MnO2 during discharge involves a reversible phase transition of MnO2 from tunneled to layered polymorphs by electrochemical reactions, initiated by the dissolution of manganese from α- Mg-ion batteries during discharge process to form layered Zn-birnessite.

TL;DR: In this paper, the detailed insertion mechanism of aluminum ions into the Mo6S8 Chevrel phase in the 1-ethyl-3methylimidazolium tetrachloroaluminate ionic liquid through combined structural and electrochemical characterization was evaluated.

TL;DR: In this article, the effect of 2.5% fluorine doping on the properties of aluminum-doped lithium manganese spinel was investigated by examining the electrochemical performance and structural changes.
