I. Introduction
Lithium has become a generic term representing a
family of battery systems in which Lithium metal is
used as the active anode material or negative elec-
trode. Variations in the cathode material, or positive
electrode, and the cell electrolyte result in hundreds
of possible combinations of Lithium batteries.
Rayovac Lithium Carbon-monofluoride (BR)
batteries are a solid-cathode type which optimizes
reliability, safety, cost and performance.
