In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of lithium ion battery, comprise battery pack and battery container, described battery pack is arranged on described battery container inside, between described battery pack and described battery container, is filled with heat conductive silica gel.
Improved, also comprise fixed support, described battery pack is located in described fixed support, and described fixed support is located in described battery container, filling heat conductive silica gel between described fixed support and described battery container.
Improved, also comprise fixed support, described battery pack is fixed in described fixed support by heat conductive silica gel, and described fixed support is located in described battery container, filling heat conductive silica gel between described fixed support and described battery container.
Improved, in described fixed support, be also provided with protection module, described protection module is electrically connected with described battery pack.
Improved, described heat conductive silica gel is two component heat conductive silica gels
Improved, described battery container is Al-alloy casing or plastic casing.
The beneficial effects of the utility model:
In the utility model, between battery pack and battery container, be filled with heat conductive silica gel, adopt after technique scheme, the utlity model has following advantage: structural principle is simple, can solve antidetonation and sealing problem that lithium ion battery group exists, make the better battery pack of shock resistance, water resistance and security performance of lithium ion battery, guarantee fail safe and the useful life of the normal use of lithium ion battery.
These features of the present utility model and advantage will be below embodiment, accompanying drawing in detailed exposure.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
Fig. 1 is the structural representation of the utility model embodiment mono-;
Fig. 2 is battery pack and support bracket fastened combination schematic diagram in embodiment mono-;
Fig. 3 is the structural representation of the utility model embodiment bis-;

Embodiment
The utility model provides a kind of lithium ion battery, comprises battery pack and battery container, and described battery pack is arranged on described battery container inside, between described battery pack and described battery container, is filled with heat conductive silica gel.By be filled with heat conductive silica gel between battery pack and battery container, adopt after technique scheme, the utlity model has following advantage: structural principle is simple, can solve antidetonation and sealing problem that lithium ion battery group exists, make the better battery pack of shock resistance, water resistance and security performance of lithium ion battery, guarantee fail safe and the useful life of the normal use of lithium ion battery.
Accompanying drawing below in conjunction with the utility model embodiment is explained and illustrated the technical scheme of the utility model embodiment, but following embodiment is only preferred embodiment of the present utility model, not all.Based on the embodiment in execution mode, those skilled in the art are other embodiment that obtains under the prerequisite of not making creative work, all belong to protection range of the present utility model.
Embodiment mono-:
Shown in seeing figures.1.and.2, a kind of lithium ion battery, comprise battery pack 1 and battery container 2, described battery pack 1 is arranged on described battery container 2 inside, between battery pack 1 and described battery container 2, be filled with heat conductive silica gel 4, while specifically enforcement, after battery pack 1 is installed into battery container 2, then toward filling heat conductive silica gel 4 on battery container 2, until heat conductive silica gel 4 is full of whole battery container 2.
As preferably, the present embodiment also comprises a fixed support 3, and battery pack 1 is placed in fixed support 3, then the fixed support 3 that is equiped with battery pack 1 is installed into battery container 2 inside, last, toward battery container 2 interior filling enter heat conductive silica gel 4.
Because lithium ion battery is in overshoot or cross the situation that easily produces battery explosion put in the situation that; therefore need in battery pack 1, be electrically connected protection module; meanwhile, in order to make the structure of whole battery compacter, protection module is arranged in fixed support 3 together with battery pack 1.
In the present embodiment, as preferably, heat conductive silica gel 4 is two component heat conductive silica gels.
As further optimization, battery container 2 is Al-alloy casing or plastic casing.
Be compared to prior art occur, between battery pack 1 and battery container 3, silicagel pad is set, silicagel pad can only play antihunt action in position, setting area specific, such as: in 1 four corners of battery pack and battery container 3 junctions, silicagel pad is set, can only plays antihunt action.Cannot improve the sealing of battery, make its water proofing property can not get improving.But the water-tight of lithium ion battery is most important, it concerns the security performance of lithium ion battery.In the utility model embodiment, compare, between battery pack 1 and battery container 3, silicagel pad is set, it is filled with heat conductive silica gel between battery pack 1 and described battery container 3, make the sealing property of whole battery better, meanwhile, its anti-seismic performance is also good than silicagel pad is set.Make lithium ion battery in use, when having protected battery, also protected user.
