③ BAK

BAK's products and services include cylindrical, square and polymer cells, as well as battery packaging and battery solutions, which are mainly used in new energy vehicles, consumer products and backup energy storage.

The core business includes: consumer digital batteries, power batteries, and battery recycling. BAK's range of applications in the field of power batteries covers all models, serving more than 10 leading car companies around the world, and insisting on creating power with wisdom.

④ LISHEN

LISHEN is the first lithium-ion battery R&D and manufacturing company in China, with 25 years of experience in lithium-ion battery R&D and manufacturing. The high-end market share ranks among the top in the global lithium battery industry.

LISHEN is positioned as an international high-end supporting and technical quality company, adhering to the business philosophy of technical quality and green energy, and is committed to providing customers with overall power solutions.

Products include five series: cylindrical, prismatic, power and polymer batteries and supercapacitors. The product application covers three main areas: power, consumption, and energy storage.

⑤ FESC

Previously, the capacity of 21700 cells stopped at 5000mAh, and two 21700 cells can be used to form 10000mAh on the power bank, replacing the original use of three or even four 18650 power banks, making the product smaller and a better experience.

FESC has pushed the ceiling of 21,700 cells from 5,000mAh to a staggering 6,000mAh with a 20% increase in energy density. This means that stagnant lithium-ion cell technology has been innovated again, and it can continue to attack high capacitance.

⑥ GREAT POWER

The GREAT POWER 21700 battery cells have been in mass production for many years, and the first 21700 batteries on the market have a battery capacity of 4600mAh (there is also a 4800mAh version).

Taking the traditional 10000mAh power bank as an example, two Penghui 21700 cells can be combined into 9200mAh. This type of 21700 specification battery cell was first seen in Tesla cars.

Because of its high energy density and large effective space, it has become a new standard in the electric vehicle industry. This kind of battery cell can be used not only for electric vehicles, but also for consumer-grade power banks, flashlights, Bluetooth speakers, etc.

⑦ LG

LG's 21700 battery is 21mm in diameter, 70mm in length, and has a capacity of 5000mAh in a single cell. A warning is printed on one end of the cell, and the battery is only for OEM use, not consumer use.

If you see this label, do not use this battery. LG lithium batteries have an advantage in terms of battery materials, because LG's materials are usually developed in-house or in cooperation with material companies.

Based on LG's history in the chemical industry, LG's materials on the 21700 battery are of high quality. All steel shell, reducing the risk of short circuits caused by collision and impact.

LG battery cells have stable performance and low internal resistance, and are often used in lighting, model airplanes, remote control cars, power banks, backup power supplies, battery packs, etc.

⑧ SAMSUNG

SAMSUNG21700 the ambient temperature of lithium batteries for long-term storage is required to be -20~50°C. Precautions are printed on the battery, fire hazard, cannot be used for e-cigarettes, it is forbidden to install, carry or hold it.

Using LSD intelligent power lock technology, it can still save about 85% of the power after one year of storage, effectively reducing power loss, and is suitable for use in sweeping robots, electric bicycles, drones, solar energy storage and other fields.

⑨ SVOLT

SVOLT has a single cell capacity of 4900mAh, and the type is a high-nickel silicon-based battery, with a continuous high discharge current of up to 15A. As a power type 21700 lithium battery, it has a larger capacity and can be discharged at a high rate.

It is suitable for two-wheeled vehicles, low-speed vehicles, electric vehicles and other applications, with a charging voltage of 4.2V and a discharge voltage of 2.75V.

⑩ SILVER SKY

SILVER SKY has a large-scale lithium battery production base integrating R&D, design, production and sales, 4 high-end automated battery production lines and a daily production capacity of 360,000 battery cells.

The products are mainly 18650 series (18650 battery) and 21700 series, which are widely used in electric bicycles, power tools, smart homes, 500w portable power station, etc., which can provide global solutions and product manufacturing from battery cells to systems, and help companies create their own green new energy products.

2. Conclusion

The best top 10 21700 battery companies in the world mark a major breakthrough in technology and the market for the battery industry. It is of great significance to promote the development of the industry.

With the continuous progress of technology and the continuous expansion of the market, it is believed that 21700 power cells will be applied in more fields.
