Description
Technical field
The utility model relates to technical field of lithium ion, in particular, relates to a kind of lithium ion battery function pad.
Background technology
Lithium ion battery in use, electrolyte is understood constantly and positive electrode active material, negative electrode active material react, also can decomposition reaction be there is in electrolyte in charge and discharge process, the generation of these reactions all will consume electrolyte, cause insufficient electrolyte, lithium ion battery shows the poor electrical property such as capacity attenuation, the change of ambient temperature in charge and discharge process, can affect the performance of lithium ion battery further.
Summary of the invention
The purpose of this utility model is to provide a kind of lithium ion battery function pad, to solve the problems referred to above of existence of the prior art.
For realizing the purpose of this utility model, the utility model provides a kind of lithium ion battery function pad, comprise: described pad is placed between pole group and casing of lithium ion battery, described pad comprises shim body and imbibing hole, described shim body is provided with imbibing hole, the thickness 0-3mm of described pad, described pad has the ability of imbibition.
The utility model is placed between battery case and pole group, shell is stoped to contact with the direct of pole group, the lax porous of function pad simultaneously, more electrolyte can be absorbed, be wrapped in group surface, pole, form a metastable liquid environment at inside lithium ion cell, be conducive to lithium ion battery and given play to excellent electrical property and security performance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, 1-shim body, 2-imbibing hole.
Embodiment
In order to make the purpose of this utility model, technical scheme and beneficial effect clearly understand, below in conjunction with embodiment, the utility model is further elaborated.Should be understood to specific embodiment described herein only in order to explain the utility model, be not limited to protection range of the present utility model.
As shown in Figure 1, the utility model provides a kind of lithium ion battery function pad, comprise: described pad is placed between pole group and casing of lithium ion battery, described pad comprises shim body and imbibing hole, described shim body is provided with imbibing hole, the thickness 0-3mm of described pad, described pad has the ability of imbibition.
In a preferred embodiment, described pad is the shape of lithium ion cell electrode group side or multiple side.
Function pad of the present utility model has excellent insulation property, does not react with electrolyte, and self can draw a certain amount of electrolyte, simultaneously requirement, when insufficient electrolyte in lithium ion cell electrode group, the electrolyte in pad can automatic flow in the group of pole, when the electrolyte in the group of pole is too much, can backflow in pad, along with the increase of the charge and discharge cycles number of times of lithium ion battery, electrolyte consumption in the group of pole between positive/negative plate reduces, during the change of the environmental factors such as lithium ion battery ambient temperature, the content of the adjustment pole group electrolyte inside that function pad energy is real-time, pole group is made to be in a metastable electrolyte environment all the time, thus realize the stability of lithium ion battery, the electrical property of lithium ion battery is not had greatly changed with the change of the environmental factor such as access times and ambient temperature because of insufficient electrolyte, strengthen the stable charge/discharge of lithium ion battery, extend lithium ion battery useful life, improve lithium ion battery can the scope of application.
When lithium ion battery overcharges, electrolyte generation decomposition reaction, in the group of pole, partial electrolysis liquid is not enough, electrolyte stream now in function pad forwards in the group of pole, ensure the stability of inside lithium ion cell structure, the hazardous acts such as on fire, blast can not be there is when proceeding charging, improve the fail safe of lithium ion battery.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
