What brand is a high-quality mobile power cell?

　　With the popularization of various smartphones and tablets, more and more people have begun to realize that various digital products, especially devices based on mobile phones, cannot meet our daily needs for battery life. The emergence of mobile power sources can be said to solve the problem of various digital products running out of battery to a certain extent. So for consumers who have not been exposed to mobile power, how to choose a dazzling array of mobile power sources? A good power supply depends on the battery cell. The battery cells inside the mobile power supply are like the fuel tank and transmission system of a car, responsible for providing a continuous source of power for the entire mobile power supply. The circuit board of the mobile power supply can be seen as a control system, mainly responsible for power distribution and conversion, converting the 3.7v (or higher) voltage provided by the lithium battery cell into a standard 5v (or higher) voltage to provide power to the charged device. Therefore, the battery cell, like the engine of a car, determines whether the mobile power supply is good or bad.

　　At present, although all mobile power cells are lithium-ion batteries, the performance of the cells varies. The differences in appearance and internal formula make it difficult for first-time buyers to understand. Let's start with two types of cells that consumers trust in the market and explore the mysterious world of mobile power step by step.

　　Lithium iron phosphate (lifepo4), also known as ferroelectricity, differs from the previous two types of batteries in that the positive electrode of the battery contains iron. Iron lithium has only just started in recent years and is a promising material. Its safety performance and cycle life are incomparable to other materials, and these are also the most important technical indicators of power batteries. The life of the 1c charging and discharging cycle reaches 2000 times, and the overcharging voltage of a single battery is 30V, which does not burn, and puncture does not explode. Lithium iron phosphate positive electrode material makes it easier to use large capacity battery packs in series to meet the frequent charging and discharging needs of electric vehicles. And it has the advantages of non-toxic, pollution-free, good safety performance, wide source of raw materials, and long service life, making it an ideal positive electrode material for the new generation of lithium-ion batteries. At present, ferroelectric is mainly used for large-capacity electric buses, signal base station energy storage, and large-scale UPS applications. Among them, mobile power supplies and AA batteries have just begun to test large-scale production, which has gradually made ferroelectric widely used in medium and large capacity UPS, small energy storage batteries, lawn lamps, and electric tools.
