Abstract: An electrochemical device is described, including a first electrochemical cell, a second electrochemical cell, connected in series to the first electrochemical cell, and a biodegradable conductive adhesive may include a conductive additive and a copolymer including at least two polycaprolactone chains attached to a polymeric center block, where the polymeric center block may include polyvinyl alcohol, disposed between the first electrochemical cell and the second electrochemical cell. A biodegradable conductive adhesive includes a hydrogel which may include a copolymer having at least two polycaprolactone chains attached to a polymeric center block, where the polymeric center block may include polyvinyl alcohol. Implementations of the biodegradable conductive adhesive may include a conductive additive or a salt. The biodegradable adhesive can include a dried hydrogel, where the hydrogel is biodegradable.

Abstract: An electrochemical device is disclosed. The electrochemical device includes an anode and a cathode, and a cured electrolyte composition disposed between the anode and the cathode, where at least a portion of the electrolyte composition interpenetrates at least a portion of both the anode and the cathode. A stacked geometry electrochemical device is disclosed. The stacked geometry electrochemical device includes a first electrode and a second electrode, and a cured electrolyte composition defining a top surface in contact with the first electrode, a bottom surface in contact with the second electrode, and a peripheral edge not in contact with the first electrode and the second electrode. The device also includes a mold wall disposed at the peripheral edge surrounding and contacting the cured electrolyte composition, where at least a portion of the mold wall is transmissible to curing radiation. A method of producing an electrolyte layer of an electrochemical device is also disclosed.
