ABSTRACT:
A novel multicell electrochemical device having a plurality of bipolar carbon-plastic electrode structures and a novel method of making the device are described. A plurality of bipolar carbon-plastic electrode structures are formed by first molding thin conductive carbon-plastic sheets from heated mixtures of specified carbon and plastic, and then establishing frames of dielectric plastic material around the sheets and sealing the frames to the sheets so as to render the resulting structures liquid impermeable. A plurality of electrochemical cell elements in addition to the electrode structures, e.g. separators, spacers and the like, are also formed with dielectric plastic frames. The frames of both the electrode structures and the additional elements have projections on at least one surface. The electrode structures and the additional elements are stacked to form a group of items in an electrochemically functional arrangement. The arrangement is such that the projection of each frame contacts a frame surface of the next item in the stack. The items in the stack are joined to one another, e.g. by heat welding or ultrasonic welding, at these areas of contact so as to form a multicell electrochemical device capable of holding liquid therein.
