Description
Technical field
The present invention relates to a kind of lithium ion battery, particularly long flexible packing lithium ion battery of a kind of high-power high-capacity life-span.
Background technology
Along with the development of modernized society, mobile device has obtained application more and more widely, as the information at high speed development and communication industry, thereby has formed the wilderness demand to high-energy battery.And for the automobile industry growing up already, due to the requirement of modernized society to environmental protection, it is also badly in need of developing a kind of safety and jumbo battery.Because the specific energy of lithium battery and lithium ion battery is high, thereby obtain the attention of countries in the world, wherein liquid electrolyte lithium ion battery obtains a wide range of applications in above-mentioned field, and the flexible packing lithium ion battery of colloid or solid electrolyte also has started to obtain practicality.The performance of flexible packing lithium ion battery is better than liquid state electrolyte battery in many aspects, and the density of for example its specific energy is high, manufacture craft is simple, shape is flexible and changeable, no liquid leakage, long shelf-life, normally discharge and recharge and can not produce gas etc.
Lithium ion flexible package battery in the market, taking conventional type low capacity as main, mainly adopts takeup type and stacked two kinds of different structures.Two kinds of structures respectively have pluses and minuses, and the advantage of coiled lithium ion battery is that battery consistency is good, easily operation, and production technology arranges well, is convenient to mechanization production, and therefore production efficiency is higher, and rate of finished products is also higher; Its shortcoming is that battery volume capacity is lower, and the sky of inside battery asks and can not be fully used, and the internal resistance of cell is higher, high-rate battery discharge poor-performing.And the advantage of stack type lithium ion battery is to make full use of the inner space of battery, improve the energy density of battery, reduce the internal resistance of battery, thereby improved the heavy-current discharge performance of lithium rechargeable battery; Its shortcoming is that battery operates in preparation process and is not easy to carry out, and battery consistency is poor, rate of finished products is lower, because the battery extruding that the expansion of positive and negative plate causes in charging process causes positive and negative plate to puncture barrier film and battery short circuit occurs in the edge dressing that cuts the burrs on edges existing in process or come off, cause that the fail safe of battery reduces in addition.In prior art, it is 0.02mm that the packaging of aluminium foil mostly adopts thickness, the 8 × × × serial aluminium foil that state is H18.8 × × × serial aluminium foil is commonly used serial chemical composition silicon Si:0.40, copper Cu:1.2～2.0, magnesium Mg:2.1～2.9, zinc Zn:5.1～6.1, manganese Mn:<0.30.8011 alloy aluminium foil low cross-intensities of available technology adopting, only reach 168NPmm
2, elongation only reaches >4, Erichsen number 2～3.
Summary of the invention
Technical problem to be solved by this invention is, overcome the existing defect of above-mentioned prior art, a kind of high-efficient high-capacity three amount, long-life flexible packing lithium ion battery are provided, its battery core body can ensure heavy-current discharge performance, can ensure again battery consistency, raise the efficiency; The tensile strength of its aluminum foil material, elongation, higher than prior art index, can synchronously extend with other composite material, flow, and can meet the deep degree of polymer Li-ion battery aluminum-plastic composite membrane flexible packing material punching used.
For achieving the above object, the technical solution used in the present invention is:
The flexible packing lithium ion battery that a kind of high-power high-capacity life-span is long, comprise the pack case outside battery core body and described core body, it is characterized in that, described battery core body is outwards to be reeled centered by negative plate by barrier film, repeat to be wound on together after stack with the overlapped way of negative plate-barrier film-positive plate-barrier film and form, the bottom coating hole area of core body is 1.2-1.5mm
2the adhesive plaster of loose structure, described pack case comprises one deck aluminium foil and is coated on the resin film outside aluminium foil, described aluminium foil consist of silicon: 1.2-1.5%, iron: 0.4-0.5%, manganese: 0.08-0.1%, nickel: 0.08-0.15%, zirconium 0.05～0.1%, rare earth 0.02-0.06%, all the other are aluminium and inevitable impurity.
In another kind of flexible packing lithium ion battery provided by the invention, described aluminium foil consist of silicon: 1.2%, iron: 0.4%, manganese: 0.1%, nickel: 0.08%, zirconium 0.05%, rare earth 0.02%.
In another kind of flexible packing lithium ion battery provided by the invention, described aluminium foil consist of silicon: 1.4%, iron: 0.5%, manganese: 0.09%, nickel: 0.1%, zirconium 0.08%, rare earth 0.04%.
In another kind of flexible packing lithium ion battery provided by the invention, described resin film is nylon BOPA6 film.
Technique effect of the present invention is: adopt overlapped way to repeat to be wound on the advantage that mode together can be enjoyed stack simultaneously and reel after stack, can ensure heavy-current discharge performance, can ensure again battery consistency, raise the efficiency; Utilize aluminum foil material of the present invention, tensile strength reaches 105-110Mpa, elongation 25-28%, not only can realize synchronous extension, flow, and can meet polymer Li-ion battery aluminum-plastic composite membrane flexible packing material used punching deep degree 3～15mm or more than, meet the outer field combined strength bination of polymer Li-ion battery aluminum-plastic composite membrane flexible packing material used is worth and rushes dark right angle deeply requirement to reach punching.This aluminium foil, for the clad aluminum foil layer of polymer Li-ion battery flexible packing material, has high barrier; And aluminium foil surface can reach without oil standard, wetting surface tension force can reach 40 × 10-3NPm.
