21700 cylindrical lithium battery core significant advantages over 18650 cell include 20% higher energy density and stronger consistency. This new cell has great potential in the field of electric vehicles, mobile devices and energy storage, and will promote the development and application of battery technology.

I. INTRODUCTION to 21700 cylindrical lithium batteries

21700 cylindrical lithium battery core is a new type of lithium ion battery. Compared with the traditional 18650 cell, its diameter is larger (21mm) and its length is longer (70mm), therefore, it has higher capacity and performance. The cell is widely used in electric vehicles, mobile devices and energy storage systems.

II. Energy density increased by 20%

1. boost battery capacity: 21700 cell has a larger volume relative to 18650 cell, so it can hold more charge. This leads to a significant increase in energy density. According to statistics, the energy density of 21700 cell is about 20% higher than that of 18650 cell.

2. Improved endurance: the increase in energy density means that 21700 cell can store more electric energy under the same volume, thus prolonging the battery life. This is very important for the use of electric vehicles and mobile devices.

3. Stronger consistency

1. more stable battery assembly: 21700 cell is used as a large-capacity battery, which can provide more stable power output when assembling the battery pack. Its stronger consistency makes the performance of the battery pack more stable and reduces the problems caused by battery inconsistency.

2. Higher charging and discharging efficiency: stronger consistency means that each 21700 cell is chargingThe performance in the discharge process is closer, which reduces the energy loss, improves the charging and discharging efficiency, and prolongs the life of the battery.

IV. Application prospect and potential

1. in the field of electric vehicles: the energy density and consistency of 21700 cylindrical lithium batteries are improved, which makes them have great potential in the field of electric vehicles. High energy density and stability mean that electric vehicles can obtain longer mileage and more reliable performance.

2. Mobile Device Market: among mobile devices such as smart phones and tablets, 21700 cell applications will also provide users with longer-lasting battery life and more stable performance, improving user experience.

3. Energy storage field: With the development of renewable energy, 21700 cell has higher energy density and stronger consistency, which will become an important part of energy storage system and promote the wider application of renewable energy.

21700 the improvement of energy density and stronger consistency of cylindrical lithium batteries represent the important progress of battery technology and will bring revolutionary changes in many fields. In the future, with the continuous expansion of its application scope and the continuous improvement of technology, we have reason to expect this new cell to bring more convenient, efficient and environmentally friendly resources solutions to mankind.
