The flexible package lithium ion battery comprises an electrode plate provided with a lug in a welding way, a battery core formed by winding the electrode plate and a flexible package shell used for accommodating the battery core, wherein the widths of the two ends of the electrode plate are different; the lug is welded at the wider end of the electrode plate; the shape of the electrode plate is trapezium or triangle or right triangle. The integral battery is spindle shape or cone shape, thereby being quite appropriate for the requirements on diversity and humanization of a digital product.
Description
Technical field
The utility model relates to a kind of flexible packing lithium ion battery, relates in particular to a kind of special-shaped flexible packing lithium ion battery.
Background technology
In the last few years, development along with battery technology, lithium ion battery has characteristics such as discharging current is big, good stability, fail safe is good, capacity is big and is widely used in the product scopes such as digital product, electric tool and power toy because of it, bring great convenience for our life.Along with the variation and the hommization of digital product, existing cylindrical more and more inapplicable with rectangular cell.
Summary of the invention
At above-mentioned technological deficiency, technical problem to be solved in the utility model provides a kind of special-shaped battery.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of special-shaped flexible packing lithium ion battery, comprise the pole piece that is welded with lug, and by pole piece coiling battery that forms and the flexible package shell that holds battery, described pole piece two ends width differs, and described lug is welded on the wide end of pole piece.
Further: in above-mentioned special-shaped flexible packing lithium ion battery, described pole piece shape is a kind of in trapezoidal, triangle, the right-angled triangle.Described pole piece two ends is provided with wide section.Described pole piece two ends are equipped with does not have the empty paper tinsel of coating district, and described lug is welded on the empty paper tinsel district of the wide end of pole piece.Described flexible packing lithium ion battery core monnolithic case is spindle or taper.Described flexible package shell is that groove that two on the shell sheet is equal to size closes up the back and forms the cavity hold battery, and the termination of described groove is partly dark and the footpath is wide all inequality with footpath partly, centre.The cavity integral body that preferred described two grooves close up back formation is spindle or taper.
Compared with prior art, in above-mentioned special-shaped flexible packing lithium ion battery, comprise the pole piece that is welded with lug, and by pole piece coiling battery that forms and the flexible package shell that holds battery, described pole piece two ends width differs, and described lug is welded on the wide end of pole piece.Use the cylindrical roll pin during coiling, between the volume pin, insert two-layer barrier film according to the normal winding operation earlier, on lower floor's barrier film, place negative plate, on the barrier film of upper strata, place positive plate, begin and finish coiling.By this kind film-making, winding method, can realize electric core is made structures such as spindle, taper, meet the need of market.In addition, this kind structure has also been accomplished conserve space as far as possible, makes its energy density maximization on the basis of special construction.Make electric core on this kind architecture basics, bring into play maximum discharging efficiency simultaneously, make its volume and capacity ratio maximization.Its cell integrated shape is spindle or taper is well suited for the variation of digital product and the requirement of hommization.
