Distinguishing OH and F in Framework Materials
Our recent work using fluoro- starting materials in fluoro-media in combination with framework forming species such as T(O,F, OH)n (T = Si, P, B and other tetrahedral-forming... -
Structure of the lithium battery cathode Li2+2x(Fe,Mn)1-xSiO4
There is great interest in scaling up Li-ion batteries for use in electric vehicles, requiring cheap and safe cathodes. Li2FeSiO4 shows promising performance as a cathode but... -
Structural changes in LiMO2 anode materials
It was thought that oxides could not intercalate Li below 1.5V vs Li+/Li. We recently studied layered LiVO2, which intercalates Li at around 0.25V to form Li2VO2, making it an... -
Structural evolution in LiVS2 anode materials
Intercalation electrodes operating close to 1V vs. Li+/Li are highly desirable. They are safe and provide protection to plating Li if overcharged, while still giving a... -
A variable temperature study of polymorphism in Li2MSiO4 electrode materials
There is great interest in scaling up Li-ion batteries for use in electric vehicles, requiring cheap and safe cathodes. Recently, silicate-based cathodes have been described,... -
