Electrochemical Behavior of Solid Cathode Materials in Organic Electrolyte Lithium Batteries: Copper Sulfides

The characteristics of copper sulfide cathodes have been evaluated in typical organic electrolyte lithium batteries. The behavior of (chalcocite), (digenite), and (covellite) is discussed in terms of mechanism of reaction, discharge properties, and energy content. In view of possible use in primary, voltage‐compatible lithium batteries, shows the most interesting performance, both in terms of constancy of the operational voltage and in terms of discharge rates.
