Single Step, Electrochemical Preparation of Copper-Based Positive Electrode for Lithium Primary Cells

Materials (Basel). 2018 Oct 29;11(11):2126. doi: 10.3390/ma11112126.

Abstract

Lithium primary cells are commonly used in applications where high energy density and low self-discharge are the most important factors. This include small coin cells for electronics, power backup batteries for complementary metal-oxide-semiconductor memory or as a long-term emergency power source. In our study we present a fast, electrochemical method of the positive electrode preparation for lithium primary cells. The influence of the current density and oxygen presence in a solution on the preparation of the electrode and thus its electrochemical behavior is examined. Electrode compositions were characterized by X-ray photoelectron spectroscopy (XPS). The prepared electrodes may be used in Li cells as competition to Zn-MnO₂ primary batteries.
