Si-doped high-energy Li1.2Mn0.54Ni0.13Co0.13O2 cathode with improved capacity for lithium-ion batteries

Autor: Brian W. Sheldon, Yan Wu, Leah Nation, Christine James, Bob R. Powell, Yue Qi

Publikováno v: Journal of Materials Research. 33:4182-4191

Li[Lix/3Mn2x/3M1−x]O2 (M = Ni, Mn, Co) (HE-NMC) materials, which can be expressed as a combination of trigonal LiTMO2 (TM = transition metal) and monoclinic Li2MnO3 phases, are of great interest as high capacity cathodes for lithium-ion batteries.

Calculating Anisotropic Correlated Chemical Expansion of Oxygen and Lithium Vacancies in Li2MnO3 to Determine Vacancy Concentrations

Autor: Christine James, Leah Nation, Juchuan Li, Nancy J Dudney, Brian W. Sheldon, Yue Qi

Publikováno v: ECS Meeting Abstracts. :543-543

Lithium-excess layered cathode materials for lithium-ion batteries of the form Li2MnO3-LiMO2 (M=transition metal(s)) show high capacities (>200 mAhg-1) due to the activation of the Li2MnO3 component.1 This activation process occurs during the first c

In Situ Stress Measurements during Electrochemical Cycling of Lithium-Rich Cathodes

Autor: Christine James, Yue Qi, Juchuan Li, Brian W. Sheldon, Leah Nation, Nancy J. Dudney

Publikováno v: ECS Meeting Abstracts. :923-923

Lithium-rich layered oxides (Li1+xM1-xO2, M= Ni, Mn, Co) are attractive cathode materials for lithium ion batteries due to their high reversible capacity originating from their high lithium and manganese content. During cycling, structural changes ca
