li ion 18650 battery pack

　　Which is safe, 18650 lithium battery or polymer lithium battery?

　　If the 18650 lithium battery and polymer lithium battery have no problems in the overall design of the product, then the cause of the problem with the charging head must be found. In general, the current should be set according to the specifications of the 18650 lithium battery and polymer lithium battery manual. , Overcharging is more likely to cause battery safety risks.

　　Which kind of safety depends on the customer. Only suitable lithium battery applications around the world can ensure the safety of rechargeable batteries. Of course, consumers are also responsible for suitable applications. This is related to the safety hazards of 18650 lithium batteries and polymer lithium batteries, but it is objective Facts are not certain. Apple’s global brands have encountered lithium-ion battery problems. The lithium-ion battery in Samsung’s mobile phones also has safety risks, and the company’s market value has evaporated by more than N billion yuan.

　　A layer of aluminum-plastic film is selected for the outside of the polymer lithium battery, and a layer of high-temperature tape is outsourced. The biggest safety risks of the polymer lithium battery are liquid leakage, short circuit failure, and bag swelling. The most extreme situation is ignition and fire. . Therefore, compared with 18650, the safety factor of polymer batteries is better. However, ignition will also cause safety risks, so it is recommended that consumers try not to put large-space mobile power on pillows, dormitory beds and other places when using large-space mobile power.

　　Comparing the two batteries, the polymer lithium battery is easy to bulge and ignite if it is misused. Compared with the 18650 lithium battery, which is easy to explode if it is misused, it shows that there will be safety risks if the rechargeable battery is misused.

　　Which is better, 18650 lithium battery or polymer lithium battery?

　　1. From the conclusion of whether 18650 lithium battery or polymer lithium battery is better, but if the operation is not good, even the best battery will be easily broken, but from the perspective of battery structure, 18650 battery is more It is easy to design and assemble, and there are suitable materials for molds on the market, and the cost is relatively low; while the structure of polymer lithium batteries is very complex, in addition to considering normal electrical characteristics, it also needs to be considered The installation shape design problem of PACK, the positive stage ear is easy to break during the processing of PACK, etc.

　　2. Security is not absolute. High-quality 18650 lithium batteries are much safer than low-quality polymer batteries, so everyone should be more vigilant to identify them. Under the condition of ensuring the quality of lithium batteries, the volume of 18650 lithium batteries will be larger than that of polymer batteries, so from From a portable point of view, polymer batteries will be lighter.

　　Which battery is better? From the perspective of consumers, it may be more inclined to polymer batteries. After all, it has a lower chance of burning than 18650 batteries, and 18650 batteries may burn and explode if misused. Therefore, sometimes it may be in 18650 batteries. In front of which is better with polymers, more people choose polymers.
