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.

Mobile phone batteries, electric car and tram batteries and electric tool batteries are common in daily life.

1, in terms of shape: cylindrical and square.

2. From the 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. From the cathode materials: lithium cobaltate (C), lithium manganate (M), ternary lithium (N) and lithium ferrous phosphate (F).

Conventionally, a cylindrical 18650 battery is used, which is a cylindrical battery with a diameter of18mm and a height of 65mm.

Precautions:

First of all, 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. Keeping the lithium-ion battery charged and discharged correctly can prolong the 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 laptops.

Digital products equipped with lithium-ion batteries are exposed to the sun 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, under normal circumstances, 50% of the electricity is most conducive to the preservation of lithium-ion batteries.
