According to the utility model, the battery cell explosion-proof valves are arranged on the opposite sides of the positive electrode and the negative electrode and face the ground, so that the upper space of the battery cell does not need to reserve an explosion-proof space, the internal space of the battery cell shell is saved, and the volume energy density is improved.
Description
Technical Field
The utility model relates to the technical field of cell structures, in particular to a novel square-shell cell structure.
Background
The safety performance diameter of the lithium ion battery influences the use safety of a user, wherein the explosion-proof valve is a safety protection means on the battery cell, the pressure relief and explosion prevention effects are achieved, and the safety valve has important significance for ensuring the safety of the lithium ion battery. The explosion-proof valve of present electric core is located positive negative pole one side of electric core, and the defect of this kind of structure is as follows, and in case the battery appears the internal short circuit and releases heat, and gaseous outwards erupts by electric core inside, and the explosion-proof valve will outwards erupt after the pressure surpasss the pressure value that explosion-proof valve set for, and current explosion-proof valve just to whole car driver's cabin and passenger cabin, certain harm to personnel after explosion-proof valve erupts.
SUMMERY OF THE UTILITY MODEL
In view of the above technical problems in the related art, the present invention provides a novel square-shell electrical core structure, which can overcome the above disadvantages in the prior art.
In order to achieve the technical purpose, the technical scheme of the utility model is realized as follows:
the utility model provides a novel square shell electricity core structure, includes electric core casing and explosion-proof valve, electric core casing is just using in the battery package immediately, electric core casing upper portion is equipped with the acquisition unit, the outside top of electric core casing is equipped with positive negative pole, the outside below of electric core casing is equipped with explosion-proof valve, explosion-proof valve is located anodal and negative pole contralateral and towards ground.
Furthermore, a liquid injection hole is formed in the upper portion of the outer portion of the battery cell shell.
Further, the explosion-proof valve is of an oval groove structure.
Further, the positive electrode is arranged on the left side of the upper part outside the battery cell shell.
Further, the negative electrode is arranged on the right side of the upper portion outside the battery cell shell.
The utility model has the beneficial effects that: through setting up battery cell explosion-proof valve at positive negative pole anti-side and towards ground and then reach battery cell upper portion space and need not reserve explosion-proof space, practice thrift battery cell casing inner space, improve volume energy density.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present invention.
As shown in fig. 1 to 4, the novel square-shell battery cell structure according to the embodiment of the present invention includes a battery cell casing 3 and an explosion-proof valve 1, the battery cell casing 3 is used upright in a battery pack, an acquisition unit is disposed on the upper portion of the battery cell, an anode 4 and a cathode 2 are disposed above the outside of the battery cell casing 3, the explosion-proof valve 1 is disposed below the outside of the battery cell casing, the explosion-proof valve 1 faces the ground, the explosion-proof valve 1 is an elliptical groove structure, the anode 4 is disposed on the left side above the outside of the battery cell casing 3, the cathode 2 is disposed on the right side above the outside of the battery cell casing 3, and a liquid injection hole is disposed above the outside of the battery cell casing 3.
In order to facilitate understanding of the above-described technical aspects of the present invention, the above-described technical aspects of the present invention will be described in detail below in terms of specific usage.
When the novel square-shell battery cell structure is used specifically, the anode 4 and the cathode 2 of the novel square-shell battery cell structure are placed upwards, and the explosion-proof valve 1 faces the ground in the use process of the product, so that an explosion-proof space does not need to be reserved in the upper space of the battery cell shell 3, the internal space of the battery cell shell 3 is saved, and the volume energy density of the battery cell shell 3 is improved. If the product is out of control due to overhigh temperature, the explosion-proof valve 1 is not harmful to the driver's cab and the passenger cabin personnel after explosion.
In summary, according to the technical scheme of the utility model, the explosion-proof valves are arranged on the opposite sides of the positive electrode and the negative electrode and face the ground, so that the upper space of the cell shell does not need to reserve an explosion-proof space, the internal space of the cell shell is saved, the volume energy density is improved, and the personal damage possibly caused by the thermal runaway of the cell is eliminated.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
