摘要： A gravure coating apparatus is provided for forming a stripe-shaped coating film by means of a gravure roll having a groove between plate cylinders. The apparatus has a scraping member having: side edges each of which contacts an edge surface of one of the plate cylinders so as to be approximately aligned along the radial direction of the gravure roll and scrapes a coating solution on the edge surface; a groove-like passage for discharging the coating solution, the groove-like passage being formed in a generally central portion of the inner peripheral surface along the bottom surface of the groove so as to be aligned along the rotation direction of the gravure roll; and a tapered surface which guides the coating solution from the edges to the groove-like passage. The scraping member is disposed in the groove, whereby the coating film formed by the plate cylinders is made uniform over the entire surface using a simple configuration.

摘要： Embodiments described in this application relate generally to a system, an apparatus and/or methods for manufacturing electrodes by infusion electrolyte into compacted electrode materials. In some embodiments, a working electrode materials can be produced using an infusion mixing and manufacturing process. In some embodiments, a single-sided finished electrode can be produced directly from a dry powder mixture using an infusion mixing and manufacturing process. In some embodiments, a double-sided finished electrode can be produced directly from a dry powder mixture using an infusion mixing and manufacturing process. The electrodes produced by an infusion mixing and manufacturing process generally perform better than those produced by non-infusion processes.
