Description
Technical field
The utility model relates to lithium battery manufacturing field, in particular to a kind of li battery shell.
Background technique
Lithium battery is very widely used in people's daily life and work, lithium battery is high with its specific energy, safety is good,
Long service life, advantages of environment protection are widely used in electronics, communication, electric tool, electric vehicle, energy storage, aviation boat
It, waits fields.Battery case prevents extraneous oxygen and moisture etc. from connecing with inside battery mainly for the protection of inside battery chip
Touching.Current battery is that single layer enclosure cannot further inhibit in leakage simultaneously, and pollution range is big.
Utility model content
The purpose of the utility model is to provide the strong a kind of li battery shells of leakproofness height, protective.
Purpose of the utility model is realized as follows: a kind of li battery shell, including double casing, it further include that setting exists
The current-collecting pole of housing center, the current-collecting pole upper end are connected with positive terminal, and the positive terminal exposes upper shell, institute
It states and is provided with electrolyte between current-collecting pole and shell, the electrolyte realizes integral sealing by diaphragm seal；On the inside of the shell
It is provided with separation layer, there are three support frames to be from top to bottom arranged for the interior of shell.
Compared with prior art, the utility model has the beneficial effect that due to being provided with double casing, while in shell
Portion is provided with support frame, so that the firmness degree of shell greatly increases, while double casing prevents the leakage of electrolyte inside；
Due to inside double casing be provided with cavernous body, when occur electrolyte leakage when, can first time Electolyte-absorptive prevent
It spreads.
As a preferred embodiment of the present invention, support frame as described above is set as bearing big opposite two circular arc of pressure
Shape.
As the further preferred scheme of the utility model, sponge is provided between bottom support frame as described above and outer casing bottom
Body.
As the further preferred scheme of the utility model, support is provided between the current-collecting pole lower end and outer casing bottom
Block.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Wherein, 1 shell, 2 current-collecting poles, 3 positive terminals, 4 electrolyte, 5 diaphragm seals, 6 separation layers, 7 support frames, 8 sponges
Body, 9 supporting blocks.
Specific embodiment
As shown in Figure 1, a kind of li battery shell, including double casing 1, it further include the current-collecting pole that 1 center of shell is set
2,2 upper end of current-collecting pole is connected with positive terminal 3, and positive terminal 3 exposes 1 upper end of shell, sets between current-collecting pole 2 and shell 1
It is equipped with electrolyte 4, electrolyte 4 realizes integral sealing by diaphragm seal 5；Be provided with separation layer 6 on the inside of shell 1, inside shell 1 with
From top to bottom there are three support frames 7 for setting.
Above-mentioned support frame 7 is set as bearing big opposite two arc-shaped of pressure.
Cavernous body 8 is provided between the above-mentioned support frame 7 in bottom and 1 bottom of shell.
Supporting block 9 is provided between above-mentioned 2 lower end of current-collecting pole and 1 bottom of shell.
The working principle of the utility model is described below: in battery in use, double casing 1 can provide biggish outside
Resistance while double casing 1 prevent the leakage of electrolyte inside 4；Setting is leaked in internal cavernous body 8 when electrolyte occurs
When, can first time Electolyte-absorptive 4 prevent its diffusion, 1 overall structure of shell is firm, and protectiveness is strong.
The utility model is not limited to above-described embodiment, on the basis of technical solution disclosed by the utility model, this
For the technical staff in field according to disclosed technology contents, not needing creative labor can be special to some of which technology
Sign makes some replacements and deformation, these replacements and deformation are within the protection scope of the present utility model.
