The type selection of mobile power supply

Source: 2020 - 04 - 10 20:54 hits: polymer battery or 18650 mobile battery power type selection of mobile power supply safer or 18650 polymer battery technology is more mature debate has never stopped. In simple terms, the biggest advantages of polymer battery plasticity, which makes the mobile power supply is more flexible. In addition, the high plasticity make battery fully occupy the internal space of mobile power supply, the same volume can obtain larger capacity of electric power. This is the same capacity of polymer mobile power supply more than 18650 mobile power smaller and lighter. However, the traditional 18650 the appearance of the battery with the ordinary no. 5 the battery. Battery is wrapped him in the sizzling, composed of several cells in series. Mobile power supply 18650 batteries are safer idea related to the battery shell. 18650 battery shell is made of iron, very hard, very poor toughness. When the cells inside the expansion, there is no toughness shell is easy to break. The polymer battery is to use filling paste, external use soft aluminum-plastic film packaging, more easily deformed, even if the internal expansion, is not easy to burst. However, so far, 18650 battery technology already quite mature, each big manufacturer in overvoltage protection, circuit design and other aspects of the process is quite perfect, battery explosion possibility is not high; However, in terms of polymer battery, domestic to fully grasp the technology and has perfect supporting system of the factory is not much. Indeed, polymer case rarely mobile power supply, but the long-term use of mobile power supply cause burns more cases. Therefore, said the movement of the polymer battery power supply safer than traditional 18650 battery is not completely correct. Polymer battery in the end, both the price. To tell the truth, now almost no price difference between two products of the same brand, but different types of cells, even personal mobile power supply and polymer cells are sold at a slightly higher price, manufacturers usually offer more features and more delicate equilibrium price difference. In short, the cell types should not be the main factors influencing the user to select products!
