These cells are designed to withstand consumer’s abuse, while ofering the best in class energy density.
The 21700 battery is a cylindrical lithium-ion battery with a diameter of 21mm and a length of 70mm. It offers a nominal voltage of 3.7V and a capacity of up to 5,000mAh, making it a powerful and efficient energy source. Its energy density ranges between 250 Wh/kg and 300 Wh/kg, depending on the chemistry.
Due to its increased cell size, LIB 21700 (Lithium-ion battery) format has surpassed the existing formats as it offers larger capacity and higher energy density. However, the battery pack's extended life and appropriate performance greatly relies on the temperature. Therefore, the thermal performance assessment of LIBS is quite essential.
It is good to see 21700 lithium cells gives the ability to compete and provide the replacement option to the corded tools in all-around areas by providing longer run time. Its safety property along with its high output current and energy capacity makes this battery popular among tech industries.
The larger size of the 21700 cell enables it to store more energy, making it ideal for applications requiring high power capacity, such as electric vehicles and industrial battery packs. Its dimensions also contribute to better thermal management, ensuring safer and more efficient operation.
The 21700 cell weighs approximately 60–70 grams, depending on the manufacturer and specific chemistry. While slightly heavier than the 18650 cell, this weight increase is justified by its higher capacity and energy density.
