What is a lithium battery

Lithium battery is short for lithium ion battery.

A battery consisting of a lithium oxide compound as a positive electrode and an organic solvent with a negative electrode substance (graphite, etc.). ) and lithium salt (LiPF6, etc. ) as an electrolyte.

Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries contain no metallic lithium and can be charged.

Lithium battery is short for lithium ion battery. As a new type of energy storage battery, it is gradually replacing the traditional lead-acid battery.

Common in daily life are mainly mobile phone batteries, electric cars and trams, and power tool batteries.

1, from the shape: cylindrical, square.

2. In terms of shell materials: steel shell, aluminum shell, plastic shell and aluminum-plastic film (soft bag).

3. According to energy density: capacity type and power type.

4. In terms of electrolyte: liquid lithium-ion battery, solid lithium-ion battery (polymer).

5. As for cathode materials: lithium cobaltate (C), lithium manganate (M), ternary lithium (N) and lithium ferrous phosphate (F).

Conventionally, a cylindrical 18650 battery is used, with a diameter of 18mm and a height of 65 mm..

Precautions:

1. Lithium-ion batteries can be seen everywhere in people's lives, such as various portable electronic products and car GPS. , and lithium-ion batteries have become an important component to maintain the operation of these tools. Maintaining proper charge and discharge of lithium-ion batteries can prolong battery life. Keeping the charge of lithium-ion battery at 10%~90% is beneficial to protect the battery. This means that it is not necessary to reach the maximum value when charging the batteries of digital products such as mobile phones and notebook computers.

Digital products equipped with lithium-ion batteries are exposed to sunlight or stored in high-temperature cars. It is best to turn off these products, because if the working temperature exceeds 60 degrees Celsius, lithium-ion batteries will accelerate aging. The charging temperature range of lithium battery is 0~45 degrees Celsius, and the discharging temperature range of lithium battery is 0~60 degrees Celsius.

Second, if the mobile phone battery needs to be recharged every day, the reason may be that the battery is defective or should be "retired".

For the laptop owner, if the plug is inserted for a long time, it is best to take out the battery (the high heat generated by the computer during use is not good for the laptop battery).

Third, in general, 50% of the electricity is most conducive to the preservation of lithium-ion batteries.
