What are the advantages of 21700 battery
What is 21700 battery? The meaning of 21700 battery specifically refers to a cylindrical battery with an outer diameter of 21mm and a height of 70.0mm. Companies in South Korea, my country, the United States and many other countries are using this model. Let's take you to understand the advantages of 21700 battery, and hope to help you.
Industry analysts analyze: The energy density of 21700 battery is higher than that of the well-known 18650 battery. The number of single cells in use can be greatly reduced, and the cost will be reduced after grouping.
Advantages of 21700 battery
, 21700 battery system, the energy density is about 300Wh/kg, which is more than 20% higher than the original 18650 battery energy density, the monomer capacity is increased by 35%, and the system cost is reduced by about 9%. From the very beginning, the huge advantages of 21700 battery aroused widespread concern and research in the industry.
It is conceivable that an 18650 battery has a capacity of about 2600-3600 mAh, and a 21700 battery supports more than 4000 mAh. Currently, 217005000mAh has appeared on the market. The larger capacity is more conducive to extending the battery life of modern equipment.
