Role of transition metals in layered Li[Ni, Co, Mn]O2 under electrochemical operation

TL;DR: In this paper, the authors measured the macroscopic crystal structure changes, the valence state of transition metals and the variations of interatomic distance for M-O (M: transition metal).
Journal ArticleDOI

Oxygen Reduction Properties of Bifunctional α-Manganese Oxide Electrocatalysts in Aqueous and Organic Electrolytes

TL;DR: In this article, several different preparation and morphologies of α-manganese oxide catalysts were synthesized, and their physical properties were characterized by electroconductivity and electrophoresis.
Journal ArticleDOI

Rational Growth of Various α-MnO2 Hierarchical Structures and β-MnO2 Nanorods via a Homogeneous Catalytic Route

TL;DR: In this paper, a homogeneous catalyst was successfully controlled via changing the catalyst feed way, and three novel α-MnO2 hierarchical structures, namely, urchin-like structures, sphere networks, and nanowire networks, were selectively synthesized at room temperature.

Synthesis, Characterization, and Structural Modeling of High-Capacity, Dual Functioning MnO2 Electrode/Electrocatalysts for Li-O2 Cells

TL;DR: In this paper, it has been shown that employing an α-MnO2/ramsdellite-mnO 2 electrode/electrocatalyst results in the formation of lithium-oxide-like discharge products in propylene carbonate, which has been reported to be extremely susceptible to decomposition.

Zero‐Strain Insertion Material of Li [ Li1 / 3Ti5 / 3 ] O 4 for Rechargeable Lithium Cells

TL;DR: In this paper, a defect spinel-framework structure was examined in nonaqueous lithium cells and it was shown that the lattice dimension did not change during the reaction since the reaction consists of lithium ion and electron insertion into/extraction from the solid matrix without a noticeable change in lattice dimensions.

Improved capacity retention in rechargeable 4 V lithium/lithium- manganese oxide (spinel) cells

TL;DR: In this article, the authors improved the rechargeable capacity of 4 V LixMn2O4 spinel cathodes by modifying the composition of the spinel electrode, achieving a capacity in excess of 100 mAh/g in flooded-electrolyte lithium cells.
