A method for the manufacture of an electrode for an energy storage or conversion device comprises thermally spraying a feedstock mixture comprising an effective quantity of a source of a thermally protective salt and an active material or active material precursor onto a substrate to produce a film of the active material and salt. The film can have a thickness of about 1 to about 1000 microns.In a particularly advantageous feature, the active materials which ordinarily decompose or are unavailable at the high temperatures used during thermal spray processes, such as metal chalcogenides such as pyrite, CoS2, WS2, Ni(OH)2, MnO2, and the like may be thermally sprayed to form an electrode when the feedstock mixture employs an effective amount of a source of the thermally protective salt coating. The active material feedstock may comprise microstructured or nanostructured materials, which after thermal spray results in electrodes having microstructured or nanostructured active materials, respectively.
