Abstract: Elements of an electrochemical cell using an end to end process. The method includes depositing a planarization layer, which manufactures embedded conductors of said cell, allowing a deposited termination of optimized electrical performance and energy density. The present invention covers the technique of embedding the conductors and active layers in a planarized matrix of PML or other material, cutting them into discrete batteries, etching the planarization material to expose the current collectors and terminating them in a post vacuum deposition step.
