Abstract
The utility model belongs to the technical field of batteries and discloses a packaging structure with a polymer soft battery core. The packaging structure comprises the soft battery core, wherein an electrode lug is arranged at the front end of the soft battery core; a protective plate provided with an output terminal and a front cover are connected at the front end of the battery core; a bottom shell is arranged at the tail end of the soft battery core; a hard shell body protecting layer used for realizing the packaging tightness and controlling the length dimension of a finished product wraps the soft battery core; and the front end and the rear end of the hard shell protecting layer are closely fastened with the front cover and the bottom shell in a fastened manner. As the hard shell protecting layer is arranged, the soft battery core is effectively protected, and meanwhile the hard shell protecting layer is fastened to the front cover and the bottom shell in a fastened manner so as to control the length dimension of the finished product and the packaging tightness in a better manner; the packaging structure adopts a simple structure and is convenient to process; the hard shell protecting layer is formed by processing in advance and has a thinner thickness; therefore, the battery capacity can be effectively improved to meet the market requirements of small volume and large capacity under the condition of the same battery volume.
Description
Technical field
The utility model relates to the lithium battery encapsulation technology field, relates in particular to the lithium battery encapsulating structure of polymer soft electricity core.
Background technology
Along with the development of lithium-ion electric pool technology, its cost performance improves constantly, and causes lithium battery by all trades and professions extensive use.For the polymer soft lithium battery electric core, because its electric core is softer relatively, need encapsulate electric core by hard shell, at present, the packing forms of soft electric core adopts plastic shell more, by what electric core injection mo(u)lding was encapsulated, the glue housing battery of injection moulding encapsulation not only forms burr easily, and during injection moulding molten resin material when battery in the metal die contacts, can damage the electric core in the housing, because for heat and pressure, electric core is flimsy inner member.And because the requirement of plastic mould moulding has limited the thickness of glue shell, if thickness is less than the very difficult moulding of 0.35 millimeter plastic casing thickness and easily pierced through the safety that is difficult to ensure electric core by foreign object, this reduces package thickness with lithium battery in the industry as far as possible, it is inconsistent with this idea that improves capacity to wish, but does not all have solution preferably always.
Summary of the invention
At above-mentioned technological deficiency, technical problem to be solved in the utility model provides a kind of encapsulating structure of polymer soft electricity core of simple in structure, the more volume of can packing in equal battery volume.
For solving the problems of the technologies described above; the utility model is by the following technical solutions: a kind of encapsulating structure of polymer soft electricity core; comprise that front end has the soft electric core of lug; electricity core front end is connected with the baffle and the cover of band lead-out terminal; the tail end of soft electric core is provided with drain pan; described soft electric core is enclosed with the hard shell protective layer that one deck plays encapsulation compactness effect and control finished product length dimension, and hard shell protective layer front and back end closely fastens with the mode that fastens and cover and drain pan.
Further: in the encapsulating structure of above-mentioned polymer soft electricity core, the layer wall of described hard shell protective layer is sheet metal, and sheet metal is to be fitted on the soft electric core by viscose glue.The lug of soft electric core front end links to each other with lead-out terminal on the baffle, and cover and baffle are connected the front end of soft electric core by the mode of mutual fastening.
Further again: in the encapsulating structure of above-mentioned polymer soft electricity core, described cover places the front end of soft electric core by bonding mode; Described plastic cement drain pan places the tail end of soft electric core by bonding mode.
Compared with prior art; in the encapsulating structure of above-mentioned polymer soft electricity core; it comprises that front end has the soft electric core of lug; electricity core front end is connected with the baffle and the cover of band lead-out terminal; the tail end of soft electric core is provided with drain pan; described soft electric core is enclosed with the hard shell protective layer that one deck plays encapsulation compactness effect and control finished product length dimension, and hard shell protective layer front and back end closely fastens with the mode that fastens and cover and drain pan.The utility model is fitted on polymer soft electricity core and is wrapped up one deck hard shell protective layer; effectively protect soft electric core; simultaneously the hard shell protective layer with the mode that fastens and cover and drain pan closely fastening with better control finished product length dimension and encapsulate compactness; simple in structure, easy to process; the hard shell protective layer process in advance and protective layer thickness thinner; can under equal battery volume, effectively improve battery capacity, and reach the jumbo market demands of small size.
Description of drawings
Fig. 1 is the explosive view of the utility model encapsulating structure;
Wherein 1 soft electric core, 2 hard shell protective layers, 3 baffles, 4 covers, 5 drain pans.
Embodiment
For the ease of those skilled in the art's understanding, the utility model structural principle is further described in detail below in conjunction with embodiment and accompanying drawing.
