Description

Technical Field

Background
The lithium ion battery has the advantages of environmental protection, long cycle life, good rate capability, safety and reliability, and the like, and is widely applied to various energy storage products, consumer electronic products and power battery cell products. At present, under the intense market competition, the requirements of customers on the energy density of the lithium ion battery cell are higher and higher.
In order to further improve the energy density of the soft package lithium ion battery, the invention provides a soft package aluminum-plastic battery with a single-side double-front-edge structure in the industry at present. However, since the soft package aluminum-plastic battery case is an aluminum-plastic case (i.e., the case is a layer of aluminum-plastic film), unlike the case of an aluminum-case battery, which is a stamped aluminum case, the shape of the soft package aluminum-plastic battery case needs to be processed to be as close as possible to a desired shape (e.g., a rectangular parallelepiped shape) to match the electronic product.
At present, the shaping treatment of the external shape of the soft package aluminum-plastic battery with the single-side double-front-edge structure specifically includes bending front-edge operation and bending side small-angle operation, which are currently realized through manual operation, and fig. 1 and 2 are schematic diagrams of the soft package aluminum-plastic battery with the single-side double-front-edge structure before and after shaping. In fig. 1 and 2, for the soft package aluminum-plastic battery 100, the front edge 21 before shaping is subjected to a vertical upward bending operation to obtain a shaped front edge 31; the first side edge 22 before reshaping and the second side edge 23 before reshaping are subjected to an inward small-angle bending operation to obtain a reshaped first side edge 32 and a reshaped second side edge 33.
The front edge 21 before shaping is integrally formed with the first side edge 22 before shaping and the second side edge 23 before shaping. Of course, the shaped front edge 31, the shaped first side edge 32, and the shaped second side edge 33 are also an integral body, and are only the shaped integral body.
However, the manual operation mode has the defects of poor consistency, poor controllability, low efficiency and the like, and meanwhile, the problem that sharp corners (namely, folding corner sharp points) are easily generated at the positions of the side bending small corners exists, the width size of the battery is influenced, and the popularization and application of the battery with the single-side double-front-edge structure are further influenced.
