Their main working principle is to provide electric energy to the motor through the lithium battery pack to drive the motor to operate, thereby propelling the car forward. The composition method of the lithium battery pack is to connect multiple battery cells in series and parallel to form a specific large-capacity battery pack to meet the requirements of powering electric vehicles. The multiple battery cells are connected to the collector plate through electrode sheets to realize the series and parallel connection of the battery cells.

During the welding process between the battery cell and the electrode sheet, and the electrode sheet and the current collector plate, the welding shunt port provided can increase the impedance of the welding point, make the welding point stronger, and make the welding firmer, so that the connection between the battery cell, the electrode sheet and the current collector plate is more stable, and will not fall off under the action of a large external force. And by providing a fuse part, when an abnormally large current discharge occurs in the battery cell, the fuse part can be blown in time, cutting off the power supply of the battery cell, realizing overcurrent protection for the battery cell, and ensuring the safety of the entire battery pack. The utility model also provides a battery pack including the above-mentioned electrode sheet.
