What is lithium-ion power battery?
Lithium-ion power battery is a new type of high-energy battery successfully developed in the 20th century. The negative electrode of this battery is made of graphite and other materials, and the positive electrode is made of lithium iron phosphate, lithium cobaltate, lithium titanate, etc. It was put into practical use in the 1970s. Because of its high energy, high battery voltage, wide operating temperature range, and long storage life, it has been widely used in military and civilian small electrical appliances.

What is the structure of lithium-ion power battery?
Lithium-ion power batteries usually come in two shapes: cylindrical and rectangular. The cylindrical battery adopts a spiral wound structure inside, and is formed by a very fine and highly permeable polyethylene or polypropylene or a composite film separator of polyethylene and polypropylene, which is spaced between the positive and negative electrodes. The rectangle is formed by lamination, that is, a positive electrode is placed on a separator and then a negative electrode, and so on.
What are applications of lithium-ion power battery?
With the development of microelectronics technology in the twentieth century, the number of miniaturized devices is increasing, which puts forward high requirements for power supply. Lithium-ion power batteries have entered a large-scale practical stage. It was first used in cardiac pacemakers. Due to the extremely low self-discharge rate of lithium-ion power batteries, the discharge voltage is gentle. It makes it possible to implant the pacemaker into the human body for long-term use.
Lithium-ion power batteries generally have a nominal voltage higher than 3.0 volts, and are more suitable for integrated circuit power supplies. Manganese dioxide batteries are widely used in computers, calculators, cameras, and watches.
In 2013, lithium-ion power batteries were widely used in mobile phones, which can be said to be the largest application group.
Example
1. There are many battery packs as replacements for battery pack maintenance: such as those used in notebook computers. After maintenance, it is found that when this battery pack is damaged, only individual batteries have problems. A suitable single-cell lithium battery can be selected for replacement.
2. Making a high-brightness miniature torch The author once used a single 3.6V1.6AH lithium battery with a white ultra-bright light-emitting tube to make a miniature torch, which is easy to use, small and beautiful. And due to the large capacity of the battery, it is used for half an hour on average every night, and it has been used for more than two months without charging.
3. Instead of 3V power supply. Because the single-cell lithium battery voltage is 3.6V. Therefore, only one lithium battery can replace two ordinary batteries to supply power to small home appliances such as radios, walkmans, cameras, etc. It is not only light in weight, but also has a long continuous use time.
