Problems solved by technology

[0002] At present, in order to increase the capacitance in the production process of the stacked battery, too many plates are often added during the design to achieve the purpose of stacking multiple plates to increase the capacity. The narrowing of the conductive channel between the plates will affect the usage rate of the active material of the battery, thereby affecting the battery life; therefore, there is a lack of a stacked battery that does not narrow the conductive channel after the plate is increased.

Embodiment Construction

[0041] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0042] according to Figure 1-3 As shown, a stacked battery includes an electrode plate group 1, a pressure frame 2, a tab 3 and a casing 4. The electrode plate group 1 includes a positive electrode plate and a negative electrode plate, and the positive electrode plate and the negative electrode plate are stacked alternately to form Both the positive plate and the negative plate have tab groups 5, and the tab groups 5 of two adjacent positive plates or the tab groups 5 of two adjacent negative plates are connected in parallel and cast-welded to form a positive strip or Negative electrode belt; the circumferential outer wall of the pole plate group 1 is provided with...

Abstract

The present invention provides a stacked battery, which includes a pole plate group, a pressure frame, a tab and a casing. By wrapping the pressure frame outside the pole plate group, the pressure frame is connected as a whole through buckles, so that the use of the pressure frame to The pole plate group is installed as a whole to reduce the softening and peeling of the active material caused by shaking between the pole plates during the use of the pole plate group. The shell is installed outside the pressure frame to further realize that the battery can pass through the shell during the use of the battery. Insulate and block the outside world from causing damage to the pressure frame or the plate group; the plate group can be fixed through the pressure frame, so that the distance between the positive plate and the negative plate can be unified, and the positive plate and the negative plate can be avoided due to overheating. It often causes the conductive channel narrowing caused by the thickening of the electrode plate group, thereby realizing that each conductive channel in the electrode plate can ensure the effective utilization rate of the active material of the battery; and the service life of the battery can be improved.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a stacked battery and a production method for the stacked battery. Background technique [0002] At present, in order to increase the capacitance during the production process of the stacked battery, too many plates are often added during the design to achieve the purpose of stacking multiple plates to increase the capacity. If there are more plates, the narrowing of the conductive channels between the plates will affect the utilization rate of the active material of the battery, thereby affecting the battery life; therefore, there is a lack of a stacked battery that does not narrow the conductive channels after the plates are increased. Contents of the invention [0003] The invention provides a stacked battery, which is used to realize that the conductive channel of the stacked battery will not be narrowed when the number of pole plates is increased, thereby not affecting t...
