Introduction to the classification and use of lithium batteries

At present, most electronic products are powered by lithium-ion batteries. There is also a lithium metal battery, which has not been applied due to high environmental requirements, so we generally refer to lithium batteries as lithium-ion batteries. Lithium batteries were proposed and studied in the 20th century and were first used in pacemakers. They can be categorized into different categories and application environments based on their shape, materials, manufacturing technology, electrolyte state, packaging and charge/discharge rate.lithium ion battery assembly

As far as shape is concerned, there are cylindrical and square types. Cylindrical batteries are used in flashlights, toys, etc. Square batteries are used in cell phones, computers, electric vehicles, energy storage devices, etc.

According to different materials, they can be divided into lithium manganese acid batteries, lithium cobalt acid batteries, lithium iron phosphate batteries, lithium ternary batteries and so on. Among them, lithium iron phosphate batteries are also called blade batteries, lithium ternary batteries are also called magazine batteries, and lithium manganate batteries are mainly used in electric bicycles. Lithium cobalt acid batteries are mostly used in 3C field, involving computers, electronics and communications. Blade batteries are mostly used in electric vehicles, energy storage and so on. Lithium ternary batteries are used in electric vehicles and a small number of 3C fields, such as tablet computers, cell phone headsets and so on.battery cell machine

According to the development of production technology process can be mainly divided into two types of enterprises stacked and coiled, stacked as the name suggests is stacked up by layer upon layer, based on the use of this traditional process of the battery system can only be a square battery; coiled is a layer of rolled like a pancake, we use our own cell phone batteries are basically these coiled process is designed and produced.prismatic cell assembly

According to the electrolyte state is divided into solid lithium batteries and liquid lithium batteries, the difference is that the former use solid electrolyte, the latter use liquid electrolyte, the vast majority of lithium batteries on the market are liquid lithium batteries.

Lithium battery packaging materials are also diverse, can be divided into soft bags, steel shells, aluminum shells, plastics and so on.

In the context of rapid economic and social development, the concept of charging five minutes to talk for two hours was put forward, fast charging has become the norm, according to the charging rate is divided into ordinary and fast charging two kinds, most of the cell phones now have the function of fast charging, and a small portion of the electric car can support the function of fast charging.

In summary, back to the question, the battery of the cell phone and the new energy electric vehicle battery is not the same. The battery of the cell phone is lithium cobalt acid battery, and the battery of the electric car is lithium iron phosphate battery. The use of lithium batteries affects all aspects of life, provides great convenience for life, and plays an important role in economic and social development. For the promising future market, we still have to overcome all the difficulties and contribute to the sustainable and stable development of lithium battery and solar energy industry.
