4 FAQs about Parameters of 21700 battery cells

What is a 21700 battery?

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.

Can a 21700 cylindrical battery reflect internal temperature distribution?

To establish a thermal model of the 21,700 cylindrical battery that can reflect the internal temperature distribution, thermophysical parameters including anisotropic thermal conductivity and specific heat capacity are tested through experiments. The thermal model includes the heat generation part and heat transfer part.

Is Lib 21700 a good battery format?

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.

How big is a 21700 cell?

The 21700 cell stands out due to its standardized dimensions of 21mm in diameter and 70mm in length. These measurements make it larger than the widely used 18650 cell, which measures 18mm by 65mm. This increase in size allows the 21700 to deliver higher energy storage and improved performance.
