Problems solved by technology

[0004] In order to solve the above technical problems, the present invention provides a laminated cell structure and a production method suitable for its through-type lamination and gluing. The diaphragm in the film is not uniform, the tension of the diaphragm is uncontrollable, and the tension of the diaphragm is too large, which will easily cause the phenomenon of severe stretching of the diaphragm, and can effectively solve the problem of low efficiency processing in the current lamination and gluing process

Abstract

The invention provides a laminated cell structure and a production method suitable for its through-type lamination and glue application, which belong to the technical field of battery stacking technology; the laminated cell structure includes positive pole pieces, negative pole pieces and Diaphragm sheet, the diaphragm sheet is provided between the adjacent positive electrode sheet and the negative electrode sheet; the positive electrode sheet, the diaphragm sheet, the negative electrode sheet and another diaphragm sheet are laminated The laminated cell structure is produced alternately; the production method of the through-type lamination and glue application adopts the circular stacking of each part of the laminated cell to form the above-mentioned laminated cell structure and its glued production in a track equipment completed. The present invention has high efficiency of lamination and gluing processing, can effectively solve the problems existing in current laminations such as uneven diaphragm, uncontrollable diaphragm tension, and excessive diaphragm tension may cause severe diaphragm stretching, etc., and can efficiently solve the problem of Inefficient processing in the current lamination and gluing process.

Description

technical field [0001] The invention relates to the technical field of battery lamination technology, in particular to a laminated cell structure and a production method suitable for its through-type lamination and glue application. Background technique [0002] At present, prismatic batteries mainly have winding and lamination production processes. Laminated batteries have many advantages and are widely used in the production of lithium batteries, nickel-metal hydride batteries, hydrogen fuel cells and lithium-sulfur batteries; for example: high energy density, discharge platform and volume specific capacity are higher than winding production process batteries; internal The structure is unified, and the reaction rate is relatively consistent; the internal resistance is low, which is equivalent to the parallel connection of multiple small pole pieces, which reduces the internal resistance; the high-rate discharge capacity is large, and the parallel connection of multi-pole p...
