What are the advantages of polymer battery cells?

Firstly, polymers are safer than 18650: under the same flow rate, overpressure, and overcharge conditions, the result is a bulge, one of which is an explosion, and you may think of it. Plus, the polymer has a solid core and there is no leakage of 18650 liquid core. Therefore, the safety of polymers is very high.

2、 Polymer 18650 has a smaller weight ratio, and for battery cells with a polymer ratio of 18650, a polymer core with the same volume is less than the volume of 18650, resulting in half of the weight being lighter. Therefore, when charging all mobile phones or other devices, polymer core power banks can reduce people's load burden. Due to the conversion rate without using chips, polymers can also bring us more surprises, allowing us to charge our phones a little more.

3、 Polymer cores have longer usage time and lifespan compared to 18650. Because polymers can be recharged 600 times, but only half of their 18650 capacity, this means that if a person buys a polymer power bank, it can last for two years. Therefore, if they buy an 18650 battery, it will only be scrapped after one year. Secondly, they do not have the same wear rate. After one year of use, the polymer still maintains 90% of its original capacity, and one year later, the 18650 battery capacity is only 65%. In addition, the conversion rate of the polymer is 88%, while 18650 is only 70%, so the core of the polymer can be imagined as having a longer and longer service life.

Four. The conversion rate between polymer and battery is higher than 18650. The polymer has an energy conversion rate of 88%, while 18650 has only 70%. Just like a 10000mAh power bank, if the polymer can charge this phone in 9 words, then 18650 batteries can only charge this phone 7 times.
