Abstract

Provided are electrochemical cells and methods of manufacturing these cells. An electrochemical cell comprises a positive electrode and an electrolyte layer, printed over the positive electrode. In some examples, each of the positive electrode, electrolyte layer, and negative electrode comprises an ionic liquid enabling ionic transfer. The negative electrode comprises a negative active material layer (e.g., comprising zinc), printed over and directly interfacing the electrolyte layer. The negative electrode also comprises a negative current collector (e.g., copper foil) and a conductive pressure sensitive adhesive layer. The conductive pressure sensitive adhesive layer is disposed between and adhered to, directly interfaces, and provides electronic conductivity between the negative active material layer and the negative current collector. In some examples, the conductive pressure sensitive adhesive layer comprises carbon and/or metal particles (e.g., nickel, copper, indium, and/or silver). Furthermore, the conductive pressure sensitive adhesive layer may comprise an acrylic polymer, encapsulating these particles.
