Abstract : During the 21 month period of this contract we have studied components for an all inorganic thin film lithium ion cell. During this work we have determined that thin film cathodes of LiCoO2 can be readily performed by either spray pyrolysis or spin coating. These cathodes are electrochemically active. We have also determined that thin film anodes of Li4Ti5O12 can be prepared by spray pyrolysis or spin coating. These anodes are also electrochemically active (approx. 1 .6V versus lithium). The thermal processing of this anode is very critical if one wishes to avoid inert impurities (i.e., TiO2 or Li2TiO3). Thin film electrolytes of Li(3.6)Ge(.6)V(.4)O4 have been prepared and tested in electrochemical cells with thin film cathodes of LiCoO2 and thin film anodes of Li4Ti5O12 and been shown to function. This work has made substantial progress towards preparing an all inorganic lithium ion devise by simple chemical means. jg p.2
