NOVELTY - An electrochemical cell comprises negative electrode which consists of 1st redox-active polymer and is configured to be reversibly oxidized during discharging operation and to be reversibly reduced during charging operation, positive electrode which consists of 2nd redox-active polymer and is configured to be reversibly reduced during discharging operation and to be reversibly oxidized during charging operation, and electrolyte which contains solid ion-exchange polymer and is interposed between positive and negative electrodes and configured to conduct ions in between electrodes.    USE - An electrochemical cell for device used in electric vehicle and portable computing device (all claimed).    ADVANTAGE - The copolymer or polymer blend improves mechanical stability of electrode during fabrication and/or during long-term charge- discharge cycling, increases electrical conductivity, and improves adhesion of electrodes to substrate or surface.    DETAILED DESCRIPTION - An electrochemical cell comprises negative electrode which consists of 1st redox-active polymer and is configured to be reversibly oxidized during discharging operation and to be reversibly reduced during charging operation, positive electrode which consists of 2nd redox-active polymer and is configured to be reversibly reduced during discharging operation and to be reversibly oxidized during charging operation, and electrolyte which contains solid ion-exchange polymer and is interposed between positive and negative electrodes and configured to conduct ions in between electrodes. The electrochemical cell is configured to store energy for an associated device or apparatus and provide structural features of the associated device or apparatus. INDEPENDENT CLAIMS are included for:    (1) device comprising greater than or equal to 1 electrochemical cells; and    (2) manufacture of three-dimensional device with greater than or equal to 1 electrochemical cell using a data model of the device which involves forming negative electrode in a pattern corresponding to the model, forming solid ion-exchange polymer electrolyte in a pattern corresponding to the model, forming positive electrode in a pattern corresponding to the model in which the processes are performed in any order, and repeating the forming processes to form successive layers.
