21700 battery concept and advantages

21700 battery concept and advantages

Page view
21700 battery is the model of cylindrical battery, which specifically refers to: 21-refers to the cylindrical battery with an outer diameter of 21mm; 700-refers to the cylindrical battery with a height of 70.0mm.

With the rapid development of new energy vehicles in recent years, lithium batteries have also become popular. Power batteries have always been an important field of new energy vehicles. Whoever masters power batteries will master new energy vehicles. Among the power batteries, the most eye-catching is undoubtedly the lithium-ion battery. 21700 battery is the model of cylindrical battery, which specifically refers to: 21-refers to the cylindrical battery with an outer diameter of 21mm; 700-refers to the cylindrical battery with a height of 70.0mm.

This is a new model developed to meet the requirements of electric vehicles for longer driving mileage and to improve the effective utilization of vehicle battery space. With the same material, the 21700 battery has a capacity that is 35% higher than the common 18650 cylindrical lithium battery.
The performance of the 21700 battery is much better than that of the 18650 in all aspects. In addition, compared with other battery models, the 21700 battery is similar to the more mature 18650 battery in terms of battery raw material selection, production process and technical process. Therefore, most of the production lines of 18650 and 21700 battery are compatible. Some companies have a safer way to make a fuss on the production line and move the production line closer to the compatibility of 21700 battery and 18650.
The pursuit of high specific energy for power batteries has become an irreversible trend, and many battery companies have begun to turn their attention to the 21700 battery. The production lines of some companies are imported from abroad, but the assembly is done by themselves, so you can invest less cost to realize the conversion of 18650 battery to 21700 battery.
