Abstract
The utility model relates to the technical field of a lithium battery, in particular to an improvement of a shell structure of a lithium ion power battery capable of being used as a power source. A lithium ion power battery shell is that: a shell body is composed of an inner layer, a middle layer and an outer layer. The inner layer is composed of electrolyte-resisting polyethylene PE or polypropylene PP, the middle layer is a metal layer, the outer layer is composed of nylon or polyethylene naphthalate PEN or polyamide or polyimide or polysnlfone, the inner layer and the outer layer are cohered with the metal layer into one body by means of injection molding or hot-press gluing and the like. The shell structure provides the shell body of the lithium ion power battery with a composite layered structure, the inner layer is composed of electrolyte- resisting plastics, the middle layer is the metal layer and the outer layer is composed of high temperature-resisting and ageing-resisting plastics; the structure effectively combines the rigidity of metal and the impact-resistance of the plastics, thus leading the shell of the power battery to be more reasonable, saving the production cost and the material cost and increasing the mass energy density of the battery as well.
Description
Technical field
The utility model relates to technical field of lithium batteries, relates to a kind of improvement that can be used as the lithium-ion-power cell shell mechanism of power source particularly.
Background technology
Along with the protection environment, the cry of energy savings grows to even greater heights, and the research and development lithium ion battery has been trend of the times.Lithium battery is the chemical classes power supply of new generation of showing one's talent the nineties, because it has excellent electrochemical properties and free of contamination characteristic, become the desirable supporting power supply of multiple advanced person's portable type electronic product, and the research of jumbo lithium-ion-power cell originated from about nineteen ninety-five, was mainly used in Aero-Space and electric automobile field.
The lithium-ion-power cell shell mainly contains two kinds of forms, metal-back form and aluminum-plastic packaged form membrane at present.Metal-back material cost and production cost are all higher, and change the battery that goes wrong if desired, are bound to destroy shell, can't restore; The shell of aluminum-plastic packaged form membrane is then damaged easily.
The utility model content
Technical problem to be solved in the utility model provides a kind of have sandwich construction and lithium-ion-power cell shell with low cost.
For solving the problems of the technologies described above, the technical scheme that the utility model is realized is:
Design a kind of lithium-ion-power cell shell, described outer cover body is made of internal layer, intermediate layer and skin.
As improvement of the technical scheme, internal layer is made of the polythene PE or the polypropylene PP of electrolyte resistance, the intermediate layer is a metal level, outer constitute internal layer, outer by injection moulding or hot-press gluing mode and metal level bonding formation integral body by nylon or PEN PEN or polyamide or polyimides or polysulfones.
The utility model has following remarkable result compared to existing technology:
The utility model provides the housing of the lithium-ion-power cell of composite bed type structure, internal layer is made of the plastics of electrolyte resistance, the intermediate layer is a metal level, outer then have high temperature resistant, ageing-resistant plastics to constitute, this structure effectively combines the rigidity of metal and the resistance to impact of plastics, the shell of electrokinetic cell is rationalized more, both can save production cost and material cost, can improve the mass energy density of battery again.
Description of drawings
Fig. 1 is a cross section structure schematic diagram of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with specific embodiment.
Referring to shown in Figure 1, a kind of lithium-ion-power cell shell, outer cover body is formed by connecting by internal layer 1, intermediate layer 2 and outer 3, and the thickness of each layer can design as required.
The housing profile of lithium-ion-power cell is 10mm * 63mm * 78mm square body in the present embodiment, and internal layer adopts polypropylene PP, and thickness is 0.5mm, and outer employing thickness is the polyamide of 1mm, and the injection moulding of inside and outside layer is on the aluminum interlayer of 0.1mm in thickness.Certainly skin also can be the lamination layer structure that nylon and polyimides are formed.
What the utility model was protected is the combined type shell structure of inner plastic, metal intermediate layer and outer layer plastic layer; the corrosion resistant polythene PE of then employing plastics or polypropylene PP or other corrosion-resistant plastics of internal layer contact electrolyte; intermediate metal layer then can also be that metals such as copper or steel or nickel constitute; outer then select good fluidity, be convenient to process, high temperature resistant, ageing-resistant macromolecular material, it is a kind of of nylon, PEN, polyamide and material modified polyimides thereof, polysulfones that cladding material can be selected.Certainly the housing profile can be a Common Shape such as cylindrical, square.
