Polymer lithium-ion batteries choose a layer of aluminum-plastic film for external use and a layer of high-temperature adhesive tape for business outsourcing. Polymer lithium-ion batteries have identified significant safety risks such as liquid leakage, short circuit faults, swelling, and in the most extreme case, ignition and ignition. Therefore, compared to 18650, the safety factor of polymer cells is better. However, ignition can also pose safety risks. Therefore, it is suggested that customers should avoid placing large space mobile power sources in areas such as pillowcases and dormitory beds as much as possible when using them.

Compared to 18650 lithium-ion batteries, polymer lithium-ion batteries are prone to bulging and igniting due to incorrect operation, indicating that there is a safety risk if the battery is charged incorrectly.

1. It is not easy to draw a conclusion from which is better, 18650 lithium battery or polymer lithium-ion battery. However, if the actual operation is not good, even the best rechargeable battery is very easy to break. However, from the perspective of the structure of rechargeable batteries, 18650 rechargeable batteries are relatively easy to design and assemble, and there are grinding tools suitable for raw materials in the sales market, with relatively low cost; The structural types of polymer lithium-ion batteries are very complex. In addition to fully considering all normal electrical equipment characteristics, it is also necessary to fully consider the installation and design difficulties of PACK. The positive ear during PACK production and processing is very prone to cracking.

2. Security is not absolute either. A high-quality 18650 lithium battery cell is much safer than a low-quality polymer battery cell, so everyone still needs to be vigilant to distinguish. While ensuring the quality of lithium cells, the volume of 18650 lithium cells will be larger than that of polymers. Therefore, from a portable perspective, polymer cells will be relatively lightweight.

From a consumer's perspective, which battery is good may be more inclined towards polymer batteries, as it has a lower chance of burning compared to 18650 batteries. Misoperation of 18650 batteries can pose a risk of combustion and explosion. Therefore, sometimes it may be better to choose polymer batteries than 18650 batteries.
