Journal ArticleDOI
Li2MnO3-stabilized LiMO2 (M = Mn, Ni, Co) electrodes for lithium-ion batteries
Michael M. Thackeray,Sun-Ho Kang,Christopher S. Johnson,John T. Vaughey,Roy Benedek,Stephen A. Hackney +5 more
TL;DR: In this paper, a strategy used to design high capacity (>200 mAh g−1), Li2MnO3-stabilized LiMO2 (M = Mn, Ni, Co) electrodes for lithium-ion batteries is discussed.
Journal ArticleDOI
Advances in manganese-oxide ‘composite’ electrodes for lithium-ion batteries
TL;DR: In this paper, a two-component notation is used to represent the Li2MnO3, LiMO2 and LiM2O4 components, which provide an initial capacity >250 mAh g−1 when discharged between 5 and 2.0 V vs. Li0 and a rechargeable capacity up to 250 mAhg−1 over the same potential window.
Journal ArticleDOI
The significance of the Li2MnO3 component in ‘composite’ xLi2MnO3 · (1 − x)LiMn0.5Ni0.5O2 electrodes
Christopher S. Johnson,J.-S. Kim,Christina Lefief,Naichao Li,John T. Vaughey,Michael M. Thackeray +5 more
TL;DR: In this paper, the performance of 0.3Li 2 MnO 3, 0.7LiMn 0.5 Ni 0.35 O 2 composite electrodes was compared with the behavior of electrodes that were preconditioned by acid treatment, showing that acid treatment significantly reduces the coulombic inefficiency of the initial charge/discharge cycle of the cells.
Journal ArticleDOI
Synthesis, Characterization and Electrochemistry of Lithium Battery Electrodes: xLi2MnO3·(1 − x)LiMn0.333Ni0.333Co0.333O2 (0 ≤ x ≤ 0.7)
TL;DR: In this article, the synthesis, structural and electrochemical characterization of xLi2MnO3·(1 − x)LiMn0.33Ni0.233Co0.333O2 electrodes over a wide compositional range is explored.
Journal ArticleDOI
Electrochemical and Structural Properties of xLi2M‘O3·(1−x)LiMn0.5Ni0.5O2 Electrodes for Lithium Batteries (M‘ = Ti, Mn, Zr; 0 ≤ x ⩽ 0.3)
Jeom-Soo Kim,Christopher S. Johnson,John T. Vaughey,Michael M. Thackeray,Stephen A. Hackney,Won-Sub Yoon,Clare P. Grey +6 more
TL;DR: In this article, powder X-ray diffraction, lattice imaging and lattice analysis of lithium batteries are used to study the properties of xLi2Mn 0.5Ni 0.3·(1−x)LiMn0.5O2 electrodes.
