What is the function of the lithium battery?

The total energy stored in the lithium battery is inversely proportional to its safety.With the increase in the battery capacity, the battery volume increases, the heat dissipation deteriorates, and the probability of an accident increases significantly. For lithium batteries used in mobile phones, the basic requirement is that the probability of a safety accident be less than one in a million, which is also the minimum acceptable standard for the public.

What are the main materials of lithium batteries?

(1) Carbon anode material

The anode materials used in lithium batteries are essentially Carbon materials such as artificial graphite, natural graphite, intermediate phase carbon microspheres, petroleum coke, carbon fibers and pyrolytic resin carbon.

(2) Tin-based anodic material

Tin-based anode materials can be divided into two types: tin oxide and tin-based composite oxide. Oxide is tin oxide metal in various valence states. None commercial product.

3.Nitride

No commercial product.

4.Alloy

Including tin-based alloys, silicon-based alloys, germanium-based alloys, aluminum-based alloys, antimony-based alloys, magnesium-based alloys and others alloys, there are no commercial products.

5. Nanoscale

Carbon nanotubes, nanoallied materials.

6. Nanooxides

According to the latest development trend of lithium battery power industry market in 2009, many companies have started to use Nano - tio 2 and Nano - SiO 2 to add traditional graphite, o and carbon nanotubes to greatly improve the charging and discharging performance of lithium batteries.Quantity and amount of charging and discharging.

What is the conductive coating of lithium batteries?

Conductive coatings are also referred to as pre-coatings, in the lithium battery industry, it is usually a conductive coating on the surface of the aluminum foil of the positive collector. a conductive coating is called pre-coated aluminum foil or single coating.Multi-layer aluminum foil.The conductive coating can effectively improve the adhesion of lithium battery electrode plate, reduce the amount of binder, and improve battery's electrical properties considerably. Its first experiences with batteries date back to the 1970s. With the development of new energy industries, especially ferric-lithium phosphate batteries, it has become a hot new technology or new materials in the industry. industry.

How to choose a lithium battery?

(1) For the original battery, the color and texture of the battery surface is clear, even, clean, and free from obvious scratches and damage; The lithium batteries identification must bear the model, model, rated capacity, standard voltage, positive and negative marks and manufacturer's name.Hand induction is smooth without sticking, elasticity is moderate, hand fit is good, locking is reliable; The material should be free from obvious scratches, blackening and greening, if the battery we buy does not match the above, it may be considered a counterfeit.

(2) Many cell phone manufacturers are striving to improve the technological level, increase the difficulty of counterfeit cell phones and their accessories, and further reduce the phenomenon of counterfeit parallel imports. Ordinary mobile products and their accessories should be consistent. Therefore, when we install the mobile phone lithium batteries we purchased, we should carefully compare the body and bottom of the battery. If the color and luster are the same, the original battery, otherwise the battery itself becomes darker and darker, which could be a fake battery.

The lithium batteries have been used in many fields Shenzhen Sumry Electronics Co., Ltd. Maintains close relationships with customers in lithium battery industry, and is committed to strengthening production and operation, improving quality and safety.
