Type selection of mobile power

The choice of polymer battery or 18650 battery mobile power type has never stopped the debate about whether the polymer mobile power is safer or the 18650 battery technology is more mature. Simply put, the biggest advantage of polymer batteries is plasticity, which makes mobile power more flexible. In addition, the high plasticity allows the battery to fully occupy the internal space of the mobile power supply, and the same volume can obtain a larger electrical energy capacity. This is the reason why the polymer power bank of the same capacity is smaller and lighter than the 18650 power bank. However, the appearance of the traditional 18650 battery is similar to that of ordinary no. 5Battery. The battery is wrapped in an iron plate and consists of several battery cells connected in series. The safer idea of u200bu200b18650 battery polymer mobile power is related to the battery case. The shell of the 18650 battery is generally made of iron plate, which is very hard and has poor toughness. When the cell swells inside, the non-tough shell can easily rupture. The polymer battery is filled with paste and is packaged with a soft aluminum plastic film on the outside. The outer shell is more easily deformed, and even if the interior swells, it is not easy to burst. However, so far, the 18650 battery technology has been quite mature, and the major manufacturers’ processes in overvoltage protection and circuit design have been quite complete. The possibility of battery explosion is not high; however, in polymer batteries, domestic There are not many manufacturers who master this technology and have a complete supporting system. Indeed, there are few cases of polymer mobile power explosions, but there are many cases of burns caused by long-term use of mobile power. Therefore, it is not entirely correct to say that the polymer battery mobile power supply is safer than the traditional 18650 battery. In the end, polymer batteries have a price for both. To be honest, there is almost no price difference between two products of the same brand, but different types of cells, even if personal power banks and polymer cells are sold at a slightly higher price, manufacturers usually supply more functions and a more refined balance price difference. In short, the current cell type should not be an important factor that affects the user's choice of products!
