With the development of microelectronic technology in the 20th century, miniaturization equipment is increasing day by day, putting forward high requirements on the power supply. Lithium battery then entered a large-scale practical stage.
The earliest application is the lithium sub-primary batteries, used in cardiac pacemakers. Due to the very low self-discharge rate of lithium batteries, the discharge voltage is very gentle. Making the pacemaker implanted in the human body long-term use possible.
Lithium manganese batteries generally have a nominal voltage higher than 3.0 volts, more suitable for integrated circuit power supply, widely used in computers, calculators, watches.
Lithium-ion batteries are widely used in mobile phones, laptops, power tools, electric cars, street lights standby power, lighting, home appliances, can be said that the largest application groups.
