Abstract
Solid-state lithium batteries have prospective applications as on-chip power sources for integrated circuit devices. These applications will benefit from the extremely low self-discharge of lithium systems, and the ability of batteries with intercalation electrodes to withstand prolonged periods of potentiostic charge. In this work electrode films prepared by RF-sputtering, physical vapour deposition and solvent casting are compared with a bulk material, crystalline V{sub 2}O{sub 5}. Vanadium pentoxide electrodes were investigated in cells with PEO-based polymer electrolyte and large excess of metallic lithium as negative electrode. By using these well characterized components, spurious effects from the other cell components are minimized. Vanadium pentoxide films prepared by three different techniques have been demonstrated to behave very differently as host materials for lithium insertion. None of the films investigated cycle as well as conventional composite electrodes. Although some improvements of the cycling efficiency can be expected to be obtained by optimizing cell design and cycling conditions, these results show that thin films are more difficult to operate reversibly that conventional composite electrodes. The reason is that composite electrodes incorporate compliant materials as electrolyte and binders and therefore better withstand the mechanical stresses introduced during cycling. (AB).
