Lithium titanium niobium oxides for battery electrodes
This proposal is part of a lithium ion battery research project for finding new anode materials. The redox couples Ti4+/Ti3+ and Nb5+/Nb4+ in titanium and niobium oxides show a... -
Proton diffusion in lithium imide: a quasi-elastic neutron scattering study
Li_2NH has been recently considered for H_2 storage applications. However, its low-T crystal structure is still controversial, with at least 6 options compatible with the... -
Polymorphism and Li coordination in LiFeO2 ionic conductors
Despite the importance of the LiFeO2 phases as cathode materials in lithium ion batteries, little is known about their crystal structures. In the frame of our research project... -
Crystal-chemical environment of lithium atoms in battery anode materials
We want to investigate and Rietveld-refine the crystal structures of a number of lithium titanates and niobates of interest as battery anode materials. Some of these phases have... -
Order-disorder and phase transitions in the LiFeO2 cathode materials
Despite the importance of the LiFeO2 phases as cathode materials in lithium ion batteries, little is known about their crystal structures, except that they should be based on...
