The pros and cons of about polymer battery and 18650 contrast

Source: 2020 - 04 - 19 fell hits: polymer battery and lithium battery which good? 'detailed tell you five things to polymer battery safer, 18650 battery has always been a controversial issue in each battery designers, 18650 good polymer battery and battery, polymer battery and 18650 battery, polymer battery and what is the difference between 18650 battery, polymer battery and 18650 cheap batteries, polymer battery and more than 18650 battery manufacturers, etc. 18650 polymer battery and battery is good, only 18650 battery performance of battery core and corresponding test, to find details of polymer as well as 18650 which, in the lithium battery manufacturer specialized battery performance security testing room will have the test data. Polymer battery and 18650 battery which is better? 1 the polymer batteries. Apple IPAD3 polymer lithium battery and 18650 battery brand compared to assume that apple IPAD3 three pieces of polymer lithium-ion polymer battery, 125 mm wide, 65 mm long pile 10 mm, the thickness of the total capacity is 11560 mah, panasonic lithium ion battery, 18650 long and 65 mm diameter of 18 mm 3350 mah analytical you may really like 18650 batteries, polymer, but also some people like to like the right hand side factory research and development of batteries, lithium polymer batteries do black especially basic black apple battery or batteries. 2. Polymer battery and comparative analysis of the lithium ion battery capacity and volume 18650 186509 * 9 * PI * 65 = 16540 mm3, capacity is 3350 mah, per mm3 0. 125 * 65 * 20254 mah polymer 10 = 81250 mm3, capacity is 11560 mah, per mm3 is 0. 14228 mah lithium ion, the same volume capacity is higher than polymer 42. 4%! ! Some say this is not fair, 18650 is round, it can't occupy all of the space, ok, I will use the 18650 minimum external rectangle lithium-ion 18 * 1865018 * 65 = 21060 mm3, capacity is 3350 mah, per mm3 0. 15907 mah lithium ion to win again, even if a rectangle capacity is higher than polymer 11 18650. 8%! ! 3. Polymer battery and the analysis of the weight and volume of 18650 battery lithium ion 18650 measured 46. 13 g, capacity is 3350 mah, 72 per gram. Polymer measured 210 621 mah. 91 g, capacity of 11560 mah, 54 per gram. 810 mah lithium ion won countless times, the same weight capacity than polymer 32. 5%! ! Will be compared with 18650 battery, polymer battery you will find that the polymer and lithium ion, should be about 40% higher than bulk volume. In fact, the reason is 18650 is a steel shell, so it is better than aluminum plastic film is a little bit heavy.
