The invention discloses a battery cell tandem structure, which comprises a plurality of battery cell groups, a plurality of metal plates and a pair of electrode lugs, wherein a second metal plate and a third metal plate are respectively provided with a body part and a bending part which bends and extends from the body part; anodes of a first battery cell group and cathodes of a second battery cell group are welded with a first metal plate; cathodes of the first battery cell group are welded with the body part of the second metal plate; anodes of the second battery cell group are welded with the body part of the third metal plate; anodes of a third battery cell group are welded with the bending part of the second metal plate; cathodes of the third battery cell group are welded with a fourth metal plate; cathodes of a fourth battery cell group are welded with the bending part of the third metal plate; anodes of the fourth battery cell group are welded with a fifth metal plate; and one electrode lug is arranged on the fourth metal plate, and the other electrode lug is arranged on the fifth metal plate. The battery cell tandem structure has high strength, so that the service life of abattery is prolonged.
Description
technical field [0001] The invention relates to a series structure, in particular to a series structure of electric cores. Background technique [0002] Lithium-ion batteries (Li-ion Batteries) are developed from lithium batteries. The button battery used in the camera is a lithium battery. The positive electrode material of lithium battery is manganese dioxide or thionyl chloride, and the negative electrode is lithium. After the battery assembly is completed, the battery has voltage and does not need to be charged. This kind of battery can also be charged, but the cycle performance is not good. Batteries are prohibited from charging. Later, Sony Corporation of Japan invented a lithium battery that uses carbon materials as the negative electrode and lithium-containing compounds as the positive electrode. During the charge and discharge process, there is no metal lithium, only lithium ions. This is the lithium ion battery. When the battery is charged, lithium ions are gen...
