- Jan 05, 2018 -

Lithium batteries were most early used in pacemakers.The low self-discharge rate of lithium batteries and the smooth discharge voltage allow the pacemaker implanted in the body to operate for a long time without recharging.Lithium batteries typically have a nominal voltage above 3.0 volts and are more suitable for integrated circuit power. Manganese dioxide batteries are widely used in calculators,digital cameras,and watches.In order to develop a variety of better performance,people have studied various materials, thus creating unprecedented products.Carbon anode materials,which have been actually used in lithium ion batteries,are basically carbon materials.
