Abstract: Apparatus and methods for manufacturing electrochromic cells. Layers of various inks are printed on substrates by high speed printing means. The electrochromic cells comprise layers of electrode, electrolyte, and counter electrode ink materials which are printed on at least one substrate. When an electrical voltage differential is introduced between the electrode and counter electrode layers, an electrochemical reaction occurs in the electrochemical cell.

Abstract: An enclosure assembly for a dry cell and a dry cell battery including such enclosure assembly wherein the enclosure assembly includes first and second layers of plastic material. The first layer of plastic material closely surrounds the dry cell and has physical characteristics sufficient to resist deterioration when contacted by exudate from the dry cell. Preferably, the first layer possesses chemical and physical barrier properties sufficient to retain cell exudate produced during discharge of the dry cell. The second layer closely surrounds the first layer and is fabricated from shrinkable plastic which encapsulates the first layer and produces a tight and chemically leak resistant seal around the dry cell.
