Battery application

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 phones, notebook computers, power tools, electric vehicles, street lamp backup power supplies, navigation lights, household appliances, and can be said to be the largest application.
