Early Development Of Lithium Batteries

Lithium batteries were first used in pacemakers. The advantages of lithium batteries such as extremely low self-discharge rate and gentle discharge voltage enable pacemakers implanted in the human body to operate for a long time without recharging. Lithium batteries generally have a nominal voltage higher than 3.0 volts, making them more suitable as integrated circuit power sources. Manganese dioxide batteries are widely used in calculators, digital cameras, and watches.
In order to develop varieties with better performance, people have studied various materials to create unprecedented products.
In 1992, Sony successfully developed lithium-ion batteries. Its practical application has greatly reduced the weight and volume of people's mobile phones, notebooks, calculators and other portable electronic devices.
