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

If the 18650 lithium ion battery and polymer lithium ion battery have no problems in the overall design of the product, then you must find the reason for the problem with the charging head. Under normal circumstances, follow the instructions of the 18650 lithium ion battery and polymer lithium ion battery. The set current is specified, and overcharging is very likely to cause safety risks for rechargeable batteries. Which kind of safety depends on the customer. Only suitable lithium battery applications in the world can guarantee the safety of rechargeable batteries. Naturally, customers are also responsible for suitable applications. This is related to the safety hazards of 18650 lithium-ion batteries and polymer lithium-ion batteries. But the objective facts are not certain. Well-known iPhone brands all over the world have encountered common problems with lithium batteries. The lithium batteries on Samsung’s mobile phones in South Korea also have safety risks, and the company’s market value has evaporated by more than N billion. The polymer lithium ion battery chooses a layer of aluminum-plastic film outside and a layer of high-temperature tape for business outsourcing. The polymer lithium ion battery finds that the greater safety risks are liquid leakage, short circuit failure, and expansion. The most extreme situation is caused by ignition. ,on fire. Therefore, relative to 18650, the safety factor of polymer batteries is better. However, there will be safety risks when lighting up. Therefore, it is recommended that customers do not need to put the large-space mobile power supply in pillow cores, dormitory beds and other areas when using large-space mobile power supplies. Comparing the two batteries, the wrong operation of the polymer lithium-ion battery is very easy to ignite, and the wrong operation of the 18650 lithium-ion battery is very easy to explode, indicating that if the rechargeable battery is operated incorrectly, there will be a safety risk.
