Abstract
The utility model relates to a casing of a lithium battery cell. The casing comprises a metal casing body, and an anode oxidation film is arranged on the inner surface of the casing body. By adopting the technical scheme, the utility model provides the casing of the lithium battery cell, which can prevent the casing body from being directly contacted with electrolyte through the anode oxidation film, thus further preventing the casing body from being corroded.
Description
Technical field
The utility model relates to the electric core housing field of battery, particularly a kind of shell that is used for lithium battery electric core.
Background technology
Lithium battery is that a class is a negative material by lithium metal or lithium alloy, uses the battery of non-aqueous electrolytic solution.
Lithium battery is as a kind of novel pollution-free battery, many fields have been widely applied to, its single product is commonly referred to as electric core, is several lithium batteries to be used in combination become the lithium battery group in many occasions, and can give like this needs the equipment of power supply that bigger power is provided.
Because the shell of lithium battery electric core is generally made with 3003 aluminium or 1050 aluminium or 1060 aluminium, usually aluminum hull is exactly the positive pole or the direct positively charged of the aluminum hull position of battery, and all contains impurity, therefore, aluminum hull uses for a long time and can directly contact the generation electrochemical corrosion with electrolyte, and then makes aluminum hull corrode.
Summary of the invention
The purpose of this utility model: in order to overcome the defective of prior art, the utility model provides a kind of shell of lithium battery electric core, can stop outer cover body directly to contact with electrolyte by anodic oxidation film, and then prevent that outer cover body is corroded.
The technical solution of the utility model: a kind of shell of lithium battery electric core, include metal shell body, described outer cover body inner surface is provided with anodic oxidation film.
Adopt technique scheme, anodic oxidation film is set on described outer cover body inner surface can be so that the insulation of described outer cover body inner surface, anodic oxidation is as anode with metal shell body, adopt the method for electrolysis to make its surface form sull, this oxide film resistance to wear is good, intensity is high and have good insulation property, stop outer cover body directly to contact, and then prevent that outer cover body is corroded with electrolyte.
Further setting of the present utility model: described outer cover body outer surface is provided with anodic oxidation film.
Adopt above-mentioned further setting, anodic oxidation film also is set, when using in groups, also can play a protective role lithium battery at described outer cover body outer surface.
Further setting more of the present utility model: described metal shell body is the aluminium shell body.
Adopt above-mentioned further setting again, metal shell body is the aluminium shell body, and the anodizing of aluminium cost is low, difficulty of processing is low and resistance to wear is good, intensity is high, good insulating.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
Embodiment
As shown in Figure 1, a kind of shell of lithium battery electric core includes metal shell body 1, and general outer cover body 1 includes housing 11, loam cake 12, is provided with anodic oxidation film 2 on described housing 11, loam cake 12 inner surfaces.Described metal adopts aluminium, certainly, also can adopt other metal material, still, considers from aspects such as cost, anti-wear performance, insulation property, and the utility model specific embodiment adopts aluminium to make.
In order further to improve anti-wear performance, intensity, the insulation property of li battery shell 1, in the utility model specific embodiment, on described housing 11, loam cake 12 outer surfaces, be provided with anodic oxidation film 2.
