What Are The Advantages of 21700 Lithium Battery Technology? | IMREN

Today, we can see the intensity of the automobile market. Tesla has replaced the traditional 18650 battery with 21700 lithium battery in order to have a better price performance, win more sales and strive to become the pioneer of new energy vehicles. The energy density of the 21700 lithium battery system is about 300Wh/kg, which is more than 20% higher than the 18650 battery used by the original ModelS, and the monomer capacity is increased by 35%, but the system cost is reduced by about 10%.

From the perspective of the national guidelines on the energy density of power lithium batteries, the energy density of single power battery will exceed 300Wh/kg in 2020, and the energy density of power battery system will reach 260Wh/kg. At present, the best 18650 battery can not meet this technical requirement, and the density of most domestic batteries is between 100~150Wh/kg.

Under the condition of limited time, the improvement of product model is far faster than the improvement of material, so the 21700 lithium battery that can increase the energy density by increasing the volume will become the focus of the enterprise.

Summary: 21700 lithium batteries are still very popular with battery manufacturers on the market. 21700 batteries are generally used in electric vehicles. The production equipment and process of 21700 batteries are not ready in one day. How to layout depends on the competitive strategy of battery manufacturers.
