1st, the metal shells such as traditional li battery shell box hat, aluminum hull are using totally enclosed type, since lithium battery in use can
A large amount of heat is generated, using the lithium battery of traditional li battery shell due to lacking the heat row generated during radiator work not
It goes out, heat causes internal temperature of battery drastically to increase, and can not only shorten battery but also the excessively high battery of temperature in this way
Inside can explode, and user's life can be threatened when serious.
Traditional li battery shell is made of housing and lithium battery bottom plate, and bottom plate is planar structure, is increased in cell internal pressure
In the case of big, bottom plate, which can protrude outward, to be made its deformation, explosion, even explodes, and the service life of battery is influenced, moreover, can endanger
Evil personal safety, and traditional li battery shell is mostly metal shell, and not only weight is big for this shell, corrosion resistance and absolutely
Edge is also bad, so as to make battery that bulging and electrode corrosion easily occur.

Lithium battery bottom plate is connected to, one layer of heat conductive silica gel is fixedly installed on the inner housing outer wall, between the inner housing and outer housing
It is fixedly installed finned cooling fin, the finned cooling fin is pasted onto interior shell surface by heat conductive silica gel, on the outer housing
Uniformly fixation offers heat emission hole.
Further, the aperture of the heat emission hole is 2mm.
Further, the centrally disposed arc groove to be recessed inwardly of lithium battery bottom base plate.
Further, the metal cover top center is provided with outwardly projecting projection contacts end.
Further, electrolytic liquid is filled between the inner housing and battery core.
Compared with prior art, the beneficial effects of the utility model are：
1st, the utility model electrolyte solution and is led by setting two layers of housing on the outside of battery core and being set between housing
Hot silica gel, the heat that can generate running lithium battery export rapidly, avoid being that lithium battery self-temperature is excessively high, rear heat
It is shed in air by finned cooling fin and the heat emission hole being fixed on outer housing, avoids lithium battery overheat and send out
Raw explosion,
It is recessed inwardly centered on the utility model lithium battery bottom plate and from center to external rounding off, in inside battery pressure
Flat state is gradually become in the case of power is increased, will not be protruded outward, avoids exploding, in addition to this utility model exists
Barrier layer is provided at the top of plastic plate, barrier layer improves the barrier property of li battery shell, enhances the corrosion resistance of lithium battery,
Significantly improving the service life of lithium battery reduces the abnormal conditions such as expansion during lithium battery use, capacity attenuation.
