Why 21700 batteries more and more widely used?

Source: 2020 - 03 - 29 good tidings hits: why 21700 will be more and more popular? Since the tesla Model3 began before 18650 battery replacement for 21700 lithium-ion batteries, many friends have found 21700 batteries more and more widely used. We have a growing number of 21700 pieces of batteries. In retrospect, it seems that we use 18650 batteries is not far off. Although 18650 batteries are still in use, 21700 battery production is not allow to ignore. What causes 21700 battery is on fire? Today, we will together to anatomy. What is 21700 battery 21700 batteries? 21 mm 21700 battery is defined as the diameter, height 70. 0 mm cylindrical battery. South Korea, China, the United States and many other countries are using this type. XTAR now sales two batteries, 21700, 21700, 4200 mah and 21700 3750 mah. There will be a larger capacity of 21700 5000 mah. Battery says 21700 to 21700 of the battery, tesla had to offer. 21700 battery was initially developed for tesla by panasonic. On January 4, 2017, the investor conference, tesla announced with panasonic joint development of 21700 pieces of new battery started mass production, will be super battery factory ( Gigafactory superbattery工厂) Production. Tesla CEO elon musk says, 21700 battery energy density is the highest in the world, is also the lowest cost, and the price is cheaper. On July 28, 2017, the first car is equipped with 2. 170000 cells of tesla Model3 consign is used, and become the world's first 2. Section 170000 all electric passenger cars, the lowest price is 3. 50000 dollars. 21700 battery make Model3 so far tesla's cheapest car. Can say, tesla Model 3 entirely by 21700 pieces of batteries, opened up a new stage of cylindrical battery capacity. 21700 battery advantages of introduction: 21700 battery has a higher energy density than 18650 batteries, use the number of single cells can be significantly reduced. Model 3 21700 battery energy density is about 300 wh/kg, compared to the original model s USES 18650 more than 20% higher than that of batteries, higher energy density than 18650 battery model 3 35%. The cost of the system reduces about 9%. From the beginning, 21700 huge advantage caused the industry wide attention and research. As you can imagine, a battery capacity is about 18650-2600 3600 mah, a 21700 battery capacity of more than 4000 mah. At present, the market has shown that 21700 5000 mah. And the bigger the capacity, more conducive to extend the durability of modern equipment. 21700 battery 21700 batteries because of its advantages, the energy density will be widely used in the future market. On August 4, 2017, the national standard GB/t34013 - released committee 2017 electric cars with accumulator product specification and size of the clear, included the 21700 specification and size. This means that a nationwide use 21700 batteries of new energy vehicles will be policy support. In addition, the battery manufacturers from the mainstream of the original 18650 to 21700 more convenient, don't put the equipment into the high technology upgrade cost and equipment investment. Some experts have speculated that 21700 pieces of batteries will have a growth in the future. Now stop, in addition to XTAR, domestic weft lithium energy, intelligent energy and gods has deployed 21700 battery products. In addition to the new energy vehicles, 21700 has also begun to chargers, electronic cigarettes, flashlights and hand-held yuntai and other equipment.
