Abstract :
Vanadium oxide has significant potential as the Li storage electrode in high energy density rechargeable Li batteries. We present results of the charge capacity and stability of vanadium oxide thin films deposited at various temperatures and ambient atmospheres by pulsed laser deposition from a sintered target of V/sub 6/O/sub 13/. The charging capacity of the films was measured by cycling the films in an electrochemical cell. The PLD films showed a capacity loss of as little as 2% after 100 cycles far exceeding films deposited by other methods.
