Behavior of Rapidly Quenched V 2 O 5 Glass at Cathode in Lithium Cells

摘要: A vanadium oxide glass has been prepared by a rapid quenching technique, and the electrochemical lithium insertion into Li/sub 2x/V/sub 2/O/sub 5/ is investigated. The open-circuit voltage (OCV) of cell with gradually decreased increasing stoichiometric parameter x, while OcV crystalline three plateaus. This difference suggests that homogeneous single phase exists in all over range. chemical diffusion coefficients are higher 1-2 orders magnitude than those polycrystalline {Beta}-Li/sub 5/.
