Polymer batteries and 18650 batteries in the end which is more secure?
18650 lithium is the most commonly used in electronic products, lithium batteries, often in the laptop battery as a battery used. The definition of the model is: such as 18650 type, that is, the diameter of the battery 18mm, length 65mm, cylindrical battery type.
Polymer batteries are safer.
Each have the merits of the current technology 18650 failure rate is lower, and has solved the problem of explosion.
18650 batteries exist the risk of explosion, and the polymer battery is the worst case of fire. I used the Ithink mobile power, the polymer was very good.
The polymer cell is also an integral part of a lithium-ion battery. Lithium ion secondary rechargeable battery is composed of this: batteries + protection circuit board. Rechargeable battery removal protection circuit board is the battery. He is the battery part of the rechargeable battery. The quality of the battery directly determines the quality of the rechargeable battery.
