Abstract: A method is provided for fabricating a film layer. A cathode film layer of lithium ion batteries is fabricated through atmospheric plasma spraying (APS) without using polymer adhesive. The ratio of its active substance can even reach 100%. Moreover, the cathode film layer fabricated by APS obtains pores, where, with the coordination of a liquid electrolyte, electrolyte penetration paths are provided to significantly increase the area of reaction. Hence, the effective thickness of the film layer is relatively thick and the capacity of battery is increased. As an example, the thickness of a film layer of lithium cobalt oxide fabricated accordingly reaches more than 100 microns; and its maximum electric capacity per unit area reaches 6 milliampere-hours per square centimeter (mAh/cm2). Thus, the performance of the follow-on solid-state lithium-ion battery is improved and its high-volume manufacturing cost is reduced.

Abstract: An apparatus is provided for plating a lithium (Li)-compound thin film. In the thin film, Li is obtained through thermal evaporation, and titanium (Ti) or other metal by using arc plasma. The elements converted into gas phase are co-deposited in a plasma environment with a reaction gas (oxygen) to be activated as excited atoms or molecules for reaction. In the end, all of the constituent elements are deposited on a substrate to form the Li-compound thin film. Thus, reaction efficiency is high with a fast deposition rate. The composition ratio of each element is independently determined to control its yield according to the requirement. Hence, the present invention greatly enhances the fabrication rate with lowered production cost for applications in the thin-film battery industries.
