In a specific embodiment, the connecting member 4 includes a glue layer or a double-sided adhesive tape, and under the adhesive effect of the glue layer, the adhesion effect between the battery cell 3 and the elastic member 2, and between the elastic member 2 and the separating member 1 is realized. In addition, under the bonding action of the glue layer, a plurality of parts in the electric core group are connected with each other to form a whole.

In a particular embodiment, the separator 1 comprises a release paper. The release paper is the release paper which can prevent the adhesion of the prepreg and can also protect the prepreg from being polluted, and the separating piece can be attached to the connecting piece under the action of the connecting piece by adopting the release paper as the separating piece; when the separating piece is not needed, the separating piece can be taken down from the connecting piece, and operation of technicians is facilitated.

In an alternative embodiment, the electrical core 3 completely covers the orthographic projection of the elastic member 2 based on the separating member 1 based on the orthographic projection of the separating member 1. Through being located the projection cross section of electricity core 3 with the projection cross section of elastic component 2 completely for in the thickness direction of electricity core 3, the size of elastic component 2 is less than the size of electricity core 3, makes elastic component 2 both can realize separating two adjacent electricity cores 3 in the thickness direction of electricity core 3, can reduce the material of elastic component 2 again, reduce cost.

In an alternative embodiment, the thickness of the elastic component 2 is not limited in this application, and in order to ensure the tightness and reliability of the connection between the electric core assembly and the external component, in a natural state of the elastic component 2, the length of the electric core assembly in the thickness direction of the electric core 3 is greater than the length of the external component for cooperating with the electric core assembly in the thickness direction of the electric core 3; and under the state that the elastic piece 2 is compressed, the length of the electric core group in the thickness direction of the electric core 3 is smaller than the length of an external component matched with the electric core group in the thickness direction of the electric core 3. Make the electric core group need extrude the electric core group in the installation for elastic component 2 is installed in the external component under the state of compression, and the electric core group receives appropriate initial restraint power, can delay the decay of 3 performances of electric core, prolongs electric core 3's life.

Referring to fig. 1 to 9, the embodiment of the present disclosure further provides a module, which includes an outer shell 5 and the aforementioned electric core set, where the electric core set is disposed in the outer shell 5. The outer shell 5 can protect the outer periphery of the electric core group.

In an alternative embodiment, the housing 5 has a mounting opening 6 formed therethrough in a direction perpendicular to the thickness direction of the battery cell 3. The electric core group can be arranged in the shell 5 through the mounting port 6 by the arrangement of the mounting port 6, so that the electric core group can be conveniently arranged.

In a specific embodiment, the mounting opening 6 is formed to penetrate in a length direction of the housing 5. Set up to the length direction of shell 5 through the direction of seting up with installing port 6 for after installing electric core group in shell 5, electric core 3's length direction's both sides are just facing installing port 6 and are set up, make electric core 3 be connected with other parts through installing port 6, the electric connection of electric core 3 of being convenient for.

In an alternative embodiment, the housing 5 may be provided in a welded, banded configuration. Because electric core 3 can take place the inflation at the charge-discharge cycle in-process, can show after the inflation of electric core 3 that the size can increase on electric core 3's thickness direction, along with the size increase in electric core 3 thickness direction, can make shell 5 receive the effort of inflation under electric core 3's inflation, shell 5 has the risk of connecting failure.

In a specific embodiment, the housing 5 is provided as an integral part. Through setting up shell 5 to integrated into one piece's structure, increase shell 5's inflation atress, promote the reliability that shell 5 used for electric core 3 in the group takes place the inflation back in the thickness direction, and shell 5 also can remain the effect of stable connection, avoids the module to take place to connect the condition of inefficacy, promotes the security of module in the use.

In a particular embodiment, the corners of the housing 5 are rounded. Set up to the structure setting of fillet through a plurality of corners with shell 5 for shell 5's overall shape is more slick and sly, avoids the module to take place shell 5's corner fish tail personnel's the condition in the use and takes place. In addition, each corner of the shell 5 is set to be a round corner, so that the safety in the installation process of the cell pack can be improved, and the situation that the cell 3 is scratched by the corners of the shell 5 is effectively avoided.
