With the development of microelectronics technology in the twentieth century, the number of miniaturized devices is increasing, and high requirements are placed on power supplies. Lithium batteries have entered a large-scale practical stage.
The earliest applied lithium primary battery was used in pacemakers. Since the self-discharge rate of the lithium sub-battery is extremely low, the discharge voltage is very gentle. It makes it possible to implant the pacemaker into the human body for a long time.
Lithium-manganese batteries generally have a nominal voltage higher than 3.0 volts, and are more suitable for integrated circuit power supply, and are widely used in computers, calculators, and watches.
Lithium-ion batteries are widely used in mobile phon
