摘要:
A method and system for fabricating solid-state energy-storage devices including fabrication films for devices without an anneal step, especially a cathode anneal of thin-film batteries. A film of an energy-storage device is fabricated by depositing a first material layer to a location on a substrate. Energy is supplied directly to the material forming the film. The energy can be in the form of energized ions of a second material. Supplying energy directly to the material and/or the film being deposited assists the growth of the crystalline structure of film. For lithium-ion energy-storage devices, the first material is an intercalation material, which releasably stores lithium ions therein. Supercapacitors and energy-conversion devices are also fabricated according the methods.

A porous, electronically insulating separator material, e.g. Solupor™, sheet separator (7) is disposed intermediate electrodes (3, 4) for maintaining those electrodes in a fixed spaced apart configuration. An electrolyte (not shown) is also disposed intermediate the electrodes. Collecting means in the form of a scavenging agent is grafted to separator (7) for sequestering one or more predetermined contaminants from the housing.
