This 21700 lithium-ion cell is a new generation of cylindrical steel-shell cells. It has a higher energy density than the 18650 cell, which can effectively reduce the total number of cells in the battery pack. As a result, it can enhance reliability, cut costs, and reduce the volume of the battery pack.
At present, the 21700 cell has entered the market of consumer electronics accessories and is widely used in devices such as mobile power banks and high-intensity flashlights.
This cell can sustain a maximum discharge current of 35A, and its instantaneous peak discharge current can reach 90A. Therefore, it can be used in the fields of drones and power tools.
