Lithium battery manufacturer: What are the advantages of cylindrical 21700?
Lithium ion batteries have a high energy density, with a capacity 1.5 to 2 times that of nickel hydrogen batteries of the same weight when in use, and a low self discharge rate. Cylinder 21700 is currently quite common. What are the advantages of cylinder 21700?
The cylindrical 21700 has almost no memory effect and does not contain toxic substances. These advantages of lithium-ion batteries have made it widely used in the field of new energy vehicles. The widespread use of cylinder 21700 is actually inseparable from its advantages. Many people are still unclear about these beliefs. Today I am here to explain what we need to understand in the future. In fact, this product is a model of cylindrical battery, specifically referring to a cylindrical battery with an outer diameter of 21mm; The height of the 700 finger cylindrical battery is 70.0mm. This is also the basic information of cylinder 21700. It is also something that needs to be understood more when using it in the future. And it is mainly developed to meet the requirements of electric vehicles for longer driving range, and is also a new model developed to improve the effective utilization of vehicle battery space during use. Compared to the common 18650 cylindrical lithium-ion battery, 21700 can have a capacity that is over 35% higher using the same material. If you have any questions, you can call us anytime for consultation. You can see the contact information on the official website, and you can also consult our online customer service personnel. They will help everyone solve some problems with quotation methods.
The cylindrical 21700 was also produced using
18650 batteries, but in recent years, the pursuit of high specific energy for power lithium batteries has become an irreversible trend. We have also seen many battery companies turning their attention to the layout of 21700 batteries. The advantage of the cylindrical 21700 is that it is completely compatible when in use, so some companies are more cautious in achieving compatibility between the two battery models on the production line. This is also one of its major advantages. In the future, we should also understand these when using them. At present, some companies import their production lines from abroad, but assemble them themselves, so they can achieve conversion with less cost. The relative density of the majority of domestically produced batteries in cylinder 21700 ranges from 100 to 150 watts per hour per kilogram. In addition, when using it, it is also necessary to know that its production and processing equipment, process technology, etc. cannot be prepared overnight, and it cannot be produced in large quantities without the rapid development trend of process technology. The prices of the products here are very reasonable, and the quality is guaranteed. If your industry needs it, you can come and take a look.
In summary, after reading the content of the article, you will discover the advantages of cylinder 21700, and when you see it again in the future, you should know its function and some working principles.
