The anode and cathode are spaced apart by a separator which can be porous earthenware, porous plaster, a gelled paste, or a paste-coated paper. Leclanché''s cell (Fig. 1) was a commercial success because the ingredients were inexpensive in large part because they were readily available and the manganese dioxide ore was dug from …
Trends in Cardiac Pacemaker Batteries
Introduction of a lithium iodine battery in 1975 greatly extended the pacemaker battery life (more than 10 years for some models) and replaced the mercury-zinc battery. Lithium Primary batteries are used in pacemakers since they meet the requirements of long life, low drain current and voltage characteristics.
