3.7v li-polymer battery 403040 Manufacturers

The power recovery decision-making consultation salon co sponsored by the Beijing Association for Science and Technology and the Literature and Information Center of the Chinese Academy of Sciences was held in Beijing Green Space Center yesterday. Fei Weiyang, academician of the Chinese Academy of Sciences, pointed out that in recent years, the key technology of pure electric drive has made great progress, and the core technology of electric vehicles represented by lithium ion has made a major breakthrough. However, the massive application of lithium batteries will also lead to the retirement of a large number of lithium batteries. Therefore, it is necessary to strengthen the research and development of advanced technologies for lithium battery recycling to achieve safe and efficient disassembly and overall recovery of valuable metals and prevent secondary pollution.

Lithium battery has been widely used in the market today. Maybe many people do not know the correct operation of this product. In fact, its service life is generally 10 years, depending on the application environment and usual habits. It can be used for about 10 years under normal circumstances, but the capacity will slowly decrease in the later period. Each charge can be discharged for 300~500 times. In addition, how can the service life be extended? Let's take a look at the introduction given by the lithium battery manufacturer.

The left side of the lithium iron phosphate battery is an anode composed of an olivine structure material, which is connected to the battery with aluminum foil. On the right is the negative electrode of the battery composed of carbon (graphite), which is connected to the negative electrode of the battery by a copper foil.

In the past, all mobile power supplies used 18650 batteries. Because of its light weight and large capacity, 18650 batteries have won the favor of many brands. However, with the improvement of lithium polymer battery technology, manufacturers have gradually switched to lithium polymer batteries. Why do mobile power supplies begin to use lithium polymer batteries?

、 Background of intelligent lithium battery At present, lithium-ion batteries have become popular in the market, and a large number of lithium-ion battery packs have adopted the form of multi cell series and parallel. Due to the individual differences of cells, it is impossible to achieve 100% balance between charging and discharging, so a complete set of charging management system is
