The invention provides a battery with a stack-wound battery core. The battery comprises an inner metal shell, an outer metal shell, a stack-wound battery core and an insulating rubber ring, wherein anisolating membrane is arranged between the positive electrode sheet and the negative electrode sheet of the stack-wound battery core, an isolating membrane is arranged outside the positive electrodesheet, an isolating membrane is arranged outside the negative electrode sheet, one end of the positive electrode sheet is connected with the outer metal shell through an end blank area positive current collector, one end of the negative electrode sheet is connected with the inner metal shell through an end blank area negative current collector, and the insulating rubber ring is arranged between the outer metal shell and the inner metal shell in a sealed mode. According to the invention, the stack-wound battery core is formed by stacking and winding the battery core membrane sheet, one end of the positive electrode sheet of the winding battery core is connected with the outer metal shell through the end blank area positive current collector, one end of the negative electrode sheet is connected with the inner metal shell through the end blank area negative current collector, and no electrode lug needs to be arranged, so that connection is simple.
Description
technical field [0001] The invention relates to the field of batteries, in particular to a stacked cell battery. Background technique [0002] A battery is a device containing an electrolyte solution and metal electrodes that converts chemical energy into electrical energy. A battery consists of a positive terminal at one end and a negative terminal at the other. In the prior art, a battery usually includes tabs, an outer metal shell, an inner metal shell, and a battery cell. The tabs are connected to the battery cell and the outer metal shell so that the outer metal shell becomes a positive electrode, and the tabs are connected to the battery cell and the inner metal shell. This makes the inner metal shell a negative electrode, wherein the tab needs to be connected to both the battery core and the outer metal shell or the inner metal shell, and the connection is relatively complicated. [0003] Therefore, it is necessary to provide a battery with stacked cells to solve th...
