Who is more durable polymer battery or 18650 battery

1. Which durable polymer battery or 18650 battery is durable? Firstly, the 18650 lithium ion battery is cylindrical, while the polymer battery is shaped or square. The polymer battery is packaged with aluminum plastic film, which is relatively fragile. It is easy to be scratched, dented, and broken. If the polymer battery is accidentally dropped to the ground, the positive ear of the battery is easy to break. The 18650 shell of the cylindrical battery uses a metal shell, so there will be no major problems even if it is dropped a few times. 2. Assuming the durability of polymer battery and 18650 battery is assumed to be the same ternary materials, the storage conditions of polymer and 18650 batteries, the charging and discharging conditions of polymer batteries and 18650 batteries, the use conditions of 18650 and polymer batteries, 18650 battery and polymer battery have the same cycle conditions, similar to the standard voltage, standard structure and working environment are the same, in fact, the durability of 18650 battery and polymer battery is basically indistinguishable. 3. The durability of the 18650 battery or the polymer battery depends on the application scenario. If a Bluetooth headset is durable, the 18650 battery will not fit, but if the size is not limited, it is recommended to use the 18650, which is relatively more durable. 5. It is really hard to draw conclusions about which of polymer battery or 18650 battery is durable, but if it is used improperly, even the best battery is easy to be broken, but in terms of battery structure, 18650 battery is easier to design and assemble, and it is both on the market. There are public mold supporting materials, which is relatively low in cost; while polymer batteries are more complicated in structure. In addition to considering the normal electrical performance and safety, the appearance of the PACK assembly and the problem of easy breakage of the positive electrode ear during PACK production must also be considered. . 6. From the consumer's point of view, which of polymer battery or 18650 battery is durable, it may be more inclined to polymer battery, because the probability of burning is lower than that of 18650 battery, and the misoperation of 18650 will have the risk of combustion and explosion, so Sometimes, in the face of whether 18650 battery or polymer battery is better, more people choose polymer. 7. Let's analyze which is the better cost of polymer battery and 18650 battery. The price of polymer is much more expensive at the same comparison. For example, domestic: the price of 5000MAH polymer is 35 yuan, and the price of two parallel 18650 batteries is 27. It's bucks, but 18650 is more dangerous than polymer batteries and easily explodes. My suggestion is to choose polymer batteries, safety first. Battery House believes that if there is no problem in the structural design of the 18650 lithium ion battery and the polymer lithium ion battery, then the reason for the charger is to be found. Normally, it depends on the 18650 and polymer battery specifications to set the charging current. , Overcharging is prone to battery safety issues.
