Abstract
The utility model relates to a square lithium ion battery with a packaging device of a battery cell. The square lithium ion battery mainly comprises a casing (1), the battery cell (2), a safety valve (3) and an electrode mast (4), wherein the battery cell (2) is arranged in the casing (1). The square lithium ion battery with the packaging device of the battery cell is also provided with the packaging device of the battery cell, wherein the packaging device of the battery cell comprises a pair of (U) mould frames (5), a left side closing head (6), a right side closing head (7), a left side closing plate (8), a right side closing plate (9) and a group of hoop frames (10). The utility model has the advantages that because the battery cell is packaged in the packaging device of the battery cell, the condition that the appearance of the battery cell is not pressed can be ensured, so that the battery cell can not sway and can also not deform and corrugate, the smoothness and the tightness of the battery cell can be ensured, and the final capacity and the performance of the battery are ensured.
Description
Technical field
The utility model relates to the lithium ion battery field.
Background technology
At present, after earlier positive/negative plate and barrier film being built up electric core in order during general rectangular lithium ion battery assembling, fill in the square tube housing after directly wrapping with adhesive tape, when battery capacity increases, the also corresponding increase of the thick size of the length and width of electric core, cause the lamination difficulty also to increase, four seamed edges can push to the centre when shifting and wrapping up electric core like this, fillet occurs, the wrinkling separation of pole piece in the middle of causing, can not guarantee that electric core is smooth closely, influence the performance and the capacity of battery.
Summary of the invention
The utility model just can not guarantee the smooth problem closely of electric core in order to overcome when existing rectangular lithium ion battery assembles, and a kind of rectangular lithium ion battery that guarantees the smooth charged closely core packaging system of electric core is provided.
The utility model mainly is made up of housing, electric core, safety valve and electrode column, the electricity core is placed in the housing, it also has electric core packaging system, and electric core packaging system is made up of a pair of U type frame, left side end socket, right side end socket, left side shrouding, right side shrouding and one group of hoop frame; A pair of U type frame is stuck on the electric core after fastening, on a pair of U type frame, be respectively equipped with one group of hoop frame groove, one group of hoop frame is embedded in respectively in one group of hoop frame groove on a pair of U type frame, be respectively equipped with groove on left side end socket and the right side end socket, left side end socket and right side end socket are installed in the left and right two ends of electric core respectively, a pair of U type frame two ends are inserted in respectively in the groove of left side end socket and right side end socket, and left side shrouding and right side shrouding are installed in respectively on left side end socket and the right side end socket.
The utility model has the advantages that: because electric core is encapsulated in the electric core packaging system, can guarantee that the profile of electric core is not squeezed, electric core can not be rocked, also can not be out of shape wrinklingly, can guarantee that electric core is smooth closely, guarantee the termination capacity and the performance of battery.
Description of drawings
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is left side end socket and right side end enclosure structure schematic diagram;
Accompanying drawing 3 is left side shrouding and right side closing plate structure schematic diagram;
Accompanying drawing 4 is a U type mount structure schematic diagram;
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.Utility model mainly is made up of housing 1, electric core 2, safety valve 3 and electrode column 4, electricity core 2 is placed in the housing 1, it is characterized in that it also has electric core packaging system, electric core packaging system is made up of a pair of U type frame 5, left side end socket 6, right side end socket 7, left side shrouding 8, right side shrouding 9 and one group of hoop frame 10; After fastening, a pair of U type frame 5 is stuck on the electric core 2, on a pair of U type frame 5, be respectively equipped with one group of hoop frame groove 5-1, one group of hoop frame 10 is embedded in respectively in one group of hoop frame groove 5-1 on a pair of U type frame 5, be respectively equipped with groove 8 on left side end socket 6 and the right side end socket 7, left side end socket 6 and right side end socket 7 are installed in electric core 2 left and right two ends respectively, a pair of U type frame 5 two ends are inserted in respectively in the groove 11 of left side end socket 6 and right side end socket 7, and left side shrouding 8 and right side shrouding 9 are installed in respectively on left side end socket 6 and the right side end socket 7.
Fit: use two U type frames of symmetry that electric core is blocked, U type width of frame is with electric core width, and length is longer slightly than electric core, thickness is less than electric core thickness, compress electric core during assembling earlier, be enclosed within stuck on the hoop frame groove (having hoop frame groove on the U type frame can be anti-skidding) with the hoop frame again, pressure comes loose, electricity core nature spreading is tightened, so electric core is that the plane is stressed, and four seamed edges do not stress, distortion when having avoided wrapping up with adhesive tape, in order to guarantee heat radiation, U type frame uses aluminium material simultaneously.
