Development and Characterization of a Thick-Film Printed Zinc-Alkaline Battery

Abstract

Application of thick-film printing technology to the fabrication of a zinc-alkaline battery was carried out in this study. Electrode inks were formulated using active materials in powdered form, poly͑ethene oxide͒ as binder, graphite as conductor, and water as solvent. Zinc-containing anodes and manganese dioxide cathodes were thick-film printed onto silver current collectors and assembled into cells using separator paper and potassium hydroxide electrolyte. The cells were cathode limited and had a theoretical capacity between 3 and 4 mAh. The highest discharge efficiency achieved was 97% of the theoretical capacity of the cathode at a discharge rate of 1 mA/cm 2 . Characterization of the electrochemical properties of the cell was carried out and assessed.

A Stencil Printed, High Energy Density Silver Oxide Battery Using a Novel Photopolymerizable Poly(acrylic acid) Separator

“…We have previously reported on a planar, primary Ag 2 O–Zn battery with a capacity of 3.5 A h cm −2 . Additionally, planar MnO 2 , and Zn electrodes have been screen printed and have been used to demonstrate high utilization at current densities of 1 mA cm −2 . A partially printed alkaline‐based MnO 2 –Zn battery using nylon mesh for support has realized capacities as high as 5.6 mA h cm −2 .…”

Introduction to Solution‐Deposited Inorganic Electronics

“…Several companies are now making it available in thin -fi lm format ( Figure 1.10 ). 82,83 Of course energy storage is just part of the power source problem. If the battery cannot be replaced or recharged readily, then energy harvesting must be considered.…”

“…Thick film printing is inexpensive to set up and simple to use. Recently, this technique has been investigated for battery [3] and fuel cell [4] applications. The resulting battery should be small, light, and reliable, with exceptional cycle life.…”
