Abstract
The utility model discloses an outer casing metal sheet and plastic structure of an external polymer battery and aims to provide the outer casing metal sheet and plastic structure of the external polymer battery, which has the advantages of stable battery structure and high battery capacity. The outer casing metal sheet and plastic structure of the external polymer battery comprises a casing as well as a battery cell and a guard plate, which are arranged in the casing; the casing comprises metal sheets (1) and a plastic frame (2) formed at the periphery of the metal sheet (1) by injection molding; and the metal sheet (1) and the plastic frame (2) form a whole. Through the structure, an integral battery case can be realized, the damage of a polymer battery in transit or in use can be avoided, the structure is relatively stable, and meanwhile, the total thickness of the casing is reduced.
Description
Technical field
The utility model relates to a kind of polymer external battery shell steel disc plastic cement structure.
Background technology
Energy density is high because having for polymer battery, more miniaturization, ultrathin, lightweight, and high security and the multiple clear superiorities such as low-cost, is used widely.Polymer battery under the prior art is comprised of battery core, shell, baffle and wrapper, and in order to strengthen the intensity of battery core periphery, producer generally selects the PEI(Polyetherimide) mode sticked on forms external battery.Yet in the low temperature mould filling process of polymer battery, the flat appearance degree of battery does not but often reach requirement, injection moulding to walk the glue fraction defective bigger than normal.In addition, it singly is the mode that just adopts PEI to stick on, also there are obvious deficiency in the mechanical strength of whole battery and anti-accidental shock ability, cause in transportation or when using polymer battery easily impaired, therefore, for this situation, some producer all arranges the metallic support sheet in the both sides of battery core, yet the battery case size is changeless, so just causes the volume lowering of battery, and this just exists certain inconvenience.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and the polymer external battery shell steel disc plastic cement structure that a kind of battery structure is stable, battery capacity is large is provided.
The technical scheme that the utility model adopts is: the utility model comprises housing and is arranged on described housing interior battery core and baffle; described housing comprises sheet metal and the colloid frame that is injection-moulded in described sheet metal periphery, and described sheet metal and described colloid frame are as a whole.
The beneficial effects of the utility model are: the utility model comprises housing and is arranged on described housing interior battery core and baffle; described housing comprises sheet metal and is injection-moulded in the colloid frame of described sheet metal periphery; described sheet metal and described colloid frame are as a whole; by such structure; can realize the integrated of battery case; can avoid in transportation or when using polymer battery easily impaired; make its structure more stable; simultaneously; reduced again the gross thickness of housing, so the utility model battery structure is stable, battery capacity is large.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1; the utility model comprises housing and is arranged on described housing interior battery core and baffle; described housing comprises sheet metal 1 and colloid frame 2; described sheet metal 1 is the not ultrathin steel of super many 0.1MM or the sheet material of other materials of thickness; described colloid frame 2 is to be injection-moulded on the periphery of described sheet metal 1 by glue frame mould Shooting Technique; make described sheet metal 1 and described colloid frame 2 as a whole; by such structure; can realize the integrated of battery case; can avoid in transportation or when using polymer battery easily impaired; make its structure more stable, simultaneously, reduced again the gross thickness of housing.
The utility model can be widely used in the polymer battery field.
Claims (1)
