Abstract: A method is provided for fabricating a cathode film layer of lithium ion batteries through atmospheric plasma spraying (APS) without using polymer adhesive. The ratio of active substance can approach 100%. A cathode film layer fabricated by APS is porous, 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).

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: A portable flame electric generation device having metal-supported solid oxide fuel cells includes a furnace, a heat shield structure, a plurality of metal-supported solid oxide fuel cells and a housing structure. Each of the metal-supported solid oxide fuel cells includes a porous metal substrate, a first anode layer, a second anode layer, an anode isolation layer, an electrolyte layer, a cathode isolation layer, a cathode interface layer and a cathode current-collecting layer. The metal-supported solid oxide fuel cell is capable of quickly starting up and withstanding thermal shocks, and also liquefied fuel cartridges are applied as heating and fuel sources for transforming the CO and H2 fuels into electricity via electrochemical reactions.
