Stacked battery and production method of stacked battery

Abstract

The invention provides a stacked battery. The stacked battery comprises a polar plate group, pressure frames, tabs and a shell, the pressure frames wrap the polar plate group and are connected into awhole through buckles, so that the polar plate group is mounted into a whole by utilizing the pressure frames, the situation that the active substances are softened and peeled off due to shaking amongpolar plates in the use process of the polar plate group is reduced, and the shell is mounted outside the pressure frames, and further the pressure frames or the polar plate group can be further insulated through the shell and are prevented from being damaged by the outside in the use process of the battery. The polar plate group can be fixed through the pressure frames, so that the distance between the positive plates and the negative plates can be unified, the condition that conductive channels become narrower due to thickening the polar plate group caused by the excessive positive plates and negative plates is avoided, and each conductive channel in the electrode plate can ensure the effective utilization rate of active substances of the battery, and the service life of the battery canbe prolonged.

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...

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.
