Abstract

The invention discloses a kind of rectangular soft-package batteries, it includes cover board, flexible joining part, soft pack cell, shell and pedestal, the soft pack cell is located in shell, the top of the soft pack cell is connect by flexible joining part with cover board and the cover board is located at the top of shell, and the pedestal is located at the bottom of shell.Soft pack cell has been put into shell by the present invention, and the service life of soft-package battery can effectively be extended in this way, it is possible to reduce the abrasion in use process to soft-package battery by then drawing anode and cathode by cover board.

Description

Rectangular soft-package battery
Technical field
The invention belongs to new energy field of batteries, and in particular to a kind of rectangular soft-package battery.
Background technique
Soft-package battery have have a safety feature, light-weight and capacity it is big a little, so the soft roll structure of lithium ion battery There is biggish market, development prospect is also preferable, but the intensity that soft-package battery wraps up polymer due to outside is lower, so its The service life used is shorter, and there is also the risks of leakage;This affects the use scope of soft-package battery to a certain extent.
Summary of the invention
In view of this, the main purpose of the present invention is to provide a kind of rectangular soft-package batteries.
In order to achieve the above objectives, the technical scheme of the present invention is realized as follows:
The embodiment of the present invention provides a kind of rectangular soft-package battery comprising cover board, flexible joining part, soft pack cell, shell and Pedestal, the soft pack cell are located in shell, and the top of the soft pack cell is connect by flexible joining part with cover board and described Cover board is located at the top of shell, and the pedestal is located at the bottom of shell.
In above scheme, by snapping fit attachment between the cover board and shell.
In above scheme, sealing ring is provided between the cover board and shell.
In above scheme, the annular groove for placing sealing ring is provided on the inside of the cover board.
In above scheme, the positive and negative anodes of the soft pack cell are welded with the side of a flexible joining part respectively, two soft companies It is welded with the inside of cover board the other side of fitting.
In above scheme, concave groove coupling structure is provided on the pedestal.
Compared with prior art, soft pack cell has been put into shell by the present invention, then draws anode and cathode by cover board, In this way, it is possible to reduce the abrasion in use process to soft-package battery, it can effectively extend the service life of soft-package battery.
Detailed description of the invention
Fig. 1 provides a kind of structural schematic diagram of rectangular soft-package battery for the embodiment of the present invention.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and It is not used in the restriction present invention.
The embodiment of the present invention provides a kind of rectangular soft-package battery, as shown in Figure 1 comprising cover board 1, flexible joining part 2, Soft Roll Battery core 4, shell 5 and pedestal 6, the soft pack cell 4 are located in shell 5, and the top of the soft pack cell 4 passes through flexible joining part 2 It is connect with cover board 1 and the cover board 1 is located at the top of shell 5, the pedestal 6 is located at the bottom of shell 5, plays fixed work With;Soft pack cell 4 has been put into shell 5 by the present invention, then anode and cathode is drawn by cover board 1, in this way, it is possible to which reducing makes With to the abrasion of soft-package battery, capable of effectively extending the service life of soft-package battery in the process.
By snapping fit attachment between the cover board 1 and shell 5.
It is provided with sealing ring 3 between the cover board 1 and shell 5, realizes sealing, avoids the generation of leakage.
The annular groove for placing sealing ring 3 is provided on the inside of the cover board 1.
The positive and negative anodes of the soft pack cell 4 are welded with the side of flexible joining part 2 respectively, two flexible joining parts 2 it is another It is welded with the inside of cover board 1 side.
It is provided with concave groove coupling structure on the pedestal 6, facilitates multiple soft-package battery composition battery packs.
Structure of the invention is simple, is able to extend the shelf life of soft-package battery, is also avoided that the generation of leakage.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the scope of the present invention.
