18650 lithium battery 3.7 v.Which is better, 18650 lithium battery or polymer lithium battery?

release time:2023-10-13 Hits:     Popular:AG11 battery

  

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

  If there is no problem with the overall design of the 18650 lithium battery and polymer lithium battery, then the cause of the problem with the charging head must be found. Under normal circumstances, the current must be set according to the instructions of the 18650 lithium battery and polymer lithium battery. , Overcharging can easily cause battery safety risks.

  Which kind of safety depends on the customer. Only suitable lithium battery applications worldwide can ensure the safety of rechargeable batteries. Of course, consumers are also responsible for suitable use. This is related to the safety hazards of 18650 lithium batteries and polymer lithium batteries, but objectively The facts are not certain. All the world-renowned brands of iPhone have encountered problems with lithium batteries. The lithium batteries used in mobile phones of Samsung Group also have safety risks, and the company's market value has evaporated by more than N billion.

  A layer of aluminum-plastic film is selected for the outside of the polymer lithium battery, and a layer of high-temperature tape is used for the outer cover. The biggest safety risks found in the polymer lithium battery are liquid leakage, short circuit failure, swelling of the package, and the most extreme situation is ignition and fire. . Therefore, compared to 18650, the safety factor of polymer batteries is better. However, ignition will also cause safety risks. Therefore, it is recommended that when consumers use large-space mobile power supplies, they should try not to place large-space mobile power supplies in pillow cores, dormitory beds, etc.

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

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

  1. We can draw a conclusion from whether 18650 lithium battery or polymer lithium battery is better or not. However, if the actual operation is not good, no matter how good the battery is, it will be very easy to break. However, from the perspective of the battery structure, 18650 rechargeable battery is better. It is easy to design and assemble, and there are mold-appropriate materials on the market, and the cost is relatively low; while the structure of polymer lithium batteries is very complex, in addition to considering the normal electrical characteristics, it also needs to be considered There are problems with the installation design of PACK, and the problem that the positive lugs are easily broken during PACK processing.

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

  Which battery is better? From the perspective of consumers, polymer batteries may be more preferred. After all, the probability of burning is smaller than that of 18650 batteries. Misoperation of 18650 may cause the risk of combustion and explosion, so sometimes 18650 batteries may be used. When faced with which polymer is better, more people choose polymers.
