Description
Technical field
The utility model relates to cell art, is specifically related to a kind of high-capacity button lithium battery.
Background technology
Modern society, in the life, work of people, generally use battery, the button cell sold on the market is varied, and it has different design concepts separately, makes every effort to the instructions for use that can reach different user.As applied to the electronic products such as notebook computer, field camera, digital camera, toy.
Housing 1 profile of existing button lithium battery is cylindrical structural, and its battery core 2 is square structure, this battery core 2 is being put in columniform housing 1, having inner space is greatly waste, the capacity causing battery is on the low side, especially for the battery core that some diameters are little and highly higher, volumetric specific energy is lower.
Utility model content
For above-mentioned deficiency, the purpose of this utility model is, provides a kind of smart structural design, rationally, can make full use of space, promote the high-capacity button lithium battery of battery capacity.
For achieving the above object, technical scheme provided by the utility model is: a kind of high-capacity button lithium battery, it comprises circular shell and cross section is circular battery core, the inner chamber suitable with the appearance profile of described battery core is provided with in described circular shell, described battery core is arranged in this inner chamber, this battery core is by strip shaped electric poles material webs around forming, and this strip shaped electric poles material comprises anode pole piece stacked successively, barrier film and cathode pole piece.
Improve as one of the present utility model, the upper cover that described circular shell comprises bottom and covers mutually with this bottom.
Improve as one of the present utility model, described anode pole piece is aluminium foil.Described cathode pole piece is Copper Foil.
The beneficial effects of the utility model are: reasonable in design of the present utility model, ingenious strip shaped electric poles material webs is coiled into columniform battery core, the cross-sectional profile profile of this battery core is circular, match with the inner chamber of circular shell completely, the intracavity space of circular shell can be made full use of, and then increase battery core volume, promote battery capacity, extend battery.Overall structure of the present utility model is simple, compact in addition, easy to manufacture, greatly shortens the production cycle, enhances productivity, and whole production process is succinct, is easy to realization, cost is low and effectively ensures product quality, be beneficial to wide popularization and application.
Below in conjunction with accompanying drawing and embodiment, the utility model is further illustrated.
Accompanying drawing explanation
Fig. 1 is the structural representation of traditional button cell.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the structural representation of battery core in Fig. 2.
Embodiment
Embodiment, see Fig. 2 and Fig. 3, a kind of high-capacity button lithium battery that the present embodiment provides, it comprises circular shell 1 and cross section is circular battery core 2, be provided with the inner chamber suitable with the appearance profile of described battery core 2 in described circular shell 1, described battery core 2 is arranged in this inner chamber, see Fig. 3, this battery core 2 is by strip shaped electric poles material webs around forming, and this strip shaped electric poles material comprises anode pole piece 3 stacked successively, barrier film 4 and cathode pole piece 5.Described anode pole piece 3 is preferably aluminium foil, and described cathode pole piece 5 is preferably Copper Foil.
Concrete, the upper cover that described circular shell 1 comprises bottom and covers mutually with this bottom.
During use, due to strip shaped electric poles material webs is coiled into columniform battery core 2, the cross-sectional profile profile of this battery core 2 is circular, match with the inner chamber of circular shell 1 completely, the intracavity space of circular shell 1 can be made full use of, and then increase battery core 2 volume, promote battery capacity, extend battery.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change above-mentioned execution mode and revise.Therefore, the utility model is not limited to above-mentioned embodiment, and any apparent improvement of every those skilled in the art done by basis of the present utility model, replacement or modification all belong to protection range of the present utility model.In addition, although employ some specific terms in this specification, these terms just for convenience of description, do not form any restriction to the utility model.As described in the utility model above-described embodiment, adopt structure same or analogous with it and the battery of other structure obtained, all in the utility model protection range.
