What are the advantages of polymer batteries?
First of all, the polymer is safer than 18650: under the same flow, overpressure, and overcharge, the result is a bulge, and one of the results is an explosion. You may think of it. In addition, the polymer is a solid core, and there is no leakage of the 18650 liquid core. Therefore, the safety of the polymer is high.
2. The weight ratio of the polymer 18650 is smaller, and the polymer is smaller than the 18650 battery. The volume of the polymer core of the same volume is less than the volume of 18650, and half of the weight is also light. Therefore, when charging all mobile phones or other devices, the polymer core mobile power can reduce people's load. Since the conversion rate of the core is not used, the polymer can also bring us more surprises, let us charge a little more mobile phone.
3. Compared with 18650, the polymer core has longer service time and life. Because the polymer can be recharged 600 times, but only half of his 18650, which means that if a person buys a polymer power bank can be used for two years, so he bought a 18650 battery for one year to scrap the power bank. Second, they do not have the same wear rate. After a year of use, the polymer still maintains 90% of its original capacity, and a year later, the 18650 battery capacity is only 65%. In addition, the conversion rate of the polymer is 88%, and 18650 is only 70%, so the core of the polymer can be imagined as a longer and longer service life of the polymer.
four. The conversion rate of polymer to battery is higher than 18650. Polymer has 88% energy conversion rate, 18650 is only 70%. Just like a 10,000 mAh power bank, if the polymer can charge the phone with 9 words, the 18650 battery can only charge the phone 7 times.
