Lithium batteries are generally composed of positive electrode materials andnegative electrode materials. Cathode materials include lithium nickelate, lithium manganate, ternary, lithium acid, lithium iron phosphate, etc., while negative electrode materials generally include amorphous carbon materials , graphitized carbon materials and silicon-based materials, nitrides. , new alloys, etc.
Also, if you search based on the chemicals lithium batteries are made of, there will be more. Such as general electrolyte, CMC, lithium cobalt oxide, separator, PVDF, high temperature tape, NMP, graphite negative electrode, SBR, oxalic acid, foil copper, aluminum foil, etc. These are the constituent materials of lithium batteries.

In order to prevent excessive discharge or overcharge of the battery due to misuse, a triple protection mechanism is installed in the single lithium-ion battery. . The first is to use a switching element. As the temperature inside the battery increases, its resistance increases accordingly. When the temperature is too high, the power supply will be automatically shut down.
The second is to choose the. suitable separator material. When the temperature reaches a certain value, the micron-sized pores on the separator automatically dissolve, preventing lithium ions from passing through, and the internal reaction of the battery stops. The third is to implement security. valve (that is, the vent hole on the top of the battery), and the internal pressure of the battery will increase when it reaches a certain value, theSafety valve opens automatically to ensure battery safety.

Lithium battery is the abbreviation of lithium-ion battery
A compound battery a lithium-oxygen compound as the positive electrode, a negative electrode material (graphite, etc.), and an organic solvent dissolved in lithium salt (LiPF6, etc.) as the electrolyte.
Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable.
Lithium battery is short for lithium-ion battery. As a new type of energy storage battery, it gradually replaces the traditional lead-acid battery.
The most common batteries in daily life aret mobile phone batteries, electric vehicles and trams, as well as power tool batteries.
1. From appearance: cylindrical, square.
2. Of the shell material: steel shell, aluminum shell, plastic shell, aluminum plastic film (soft packaging).
3. According to energy density: capacity type and power type.
4. Separated from the electrolyte: liquid lithium-ion battery, solid (polymer) lithium-ion battery.
5. From the perspective of positive electrode materials: lithium cobalt oxide (C), lithium manganate (M), ternary lithium (N), and lithium iron phosphate (F).
The 18650 cylindrical battery is commonly used, which is a cylindrical battery with a diameter of 18 mm and a height of 65 mm.
Notes:
First, lithium-ion batteries can be seen everywhere in people's lives, in various portable electronic products, vehicle GPS, andvs. Lithium-ion batteries have become the key to keeping these tools running.Important Parts. Keeping lithium-ion batteries properly charged and discharged can extend battery life. Keeping the lithium-ion battery power between 10% and 90% is beneficial to protect the battery. This means that when charging batteries of digital products such as mobile phones and laptops, it is not necessary to reach the maximum value.
If digital products equipped with lithium-ion batteries are exposed to sunlight or stored in hot cars, it is best to keep these products turned off because if the operating temperature exceeds 60 degrees Celsius, the lithium battery -ion will accelerate aging. Lithium battery charging temperature range: 0 ~ 45 degrees Celsius, lithium battery discharge temperature range 0 ~ 60 degrees Celsius.
Second, if the cell phone battery needs to be charged every day, the reason may be that the battery is defective or it is time to "retire".
For laptop owners, it is best to remove the battery if it is plugged in for a long time (the high heat generated by the computer while in use is not good for the battery of the laptop).
Third, under normal circumstances, 50% power is most conducive to the preservation of lithium-ion batteries.
