摘要:
A soft packaged and high capacity lithium ion battery and the manufacture method of the same, wherein the said battery comprises a battery core sealed by a complex film of aluminum-plastic. The said battery core is laminated by positive electrode plates, negative electrode plates and separators alternatively. The said positive electrode plates and negative electrode plates are divided into coating area and uncoating area along the length direction. The uncoating area of the said plurality positive electrode plates extends from the one side of the said laminated structure and folds over the top surface of the laminated structure to form positive current collector. The uncoating area of the said plurality negative electrode plates also extends from the other side of the said laminated structure and folds over the top surface of the laminated structure to form negative current collector. A large area thin aluminum plate is used as positive and negative electrode tab to confirm sufficient contact with the positive and negative current collectors in the large area. Thus the battery inner resistance is reduced and the ability of charge and discharge in large current of the battery is improved.
