Background
The lithium ion battery has the characteristics of high working voltage, high energy density, wide working temperature, long cycle life, no memory effect, environmental friendliness and the like, and has become one of the main choices of the 21 st century green battery. The lithium ion battery is widely applied to the power battery fields of automobiles, electric bicycles and the like, the energy storage fields of electric power grids, industrial energy storage, household energy storage, communication energy storage and the like, and the 3C digital fields of smart phones, notebook computers, intelligent wearing equipment, mobile power supplies and the like.
The lithium battery can generate chemical reaction in the battery during discharging, and a large amount of heat energy is generated, so that the temperature of an electric core in the battery is increased, and the temperature can be felt when the lithium battery is touched by hands, which is a common phenomenon in most lithium batteries. The battery can be aged due to frequent heating of the battery core, and if the internal air is severely expanded for a long time, the battery is outwards protruded, and the battery can be seriously burnt. Therefore, in order to ensure that heat is not generated between the cells due to heat transfer, a heat insulating pad is often interposed between the two cells. However, when the battery cells are assembled, due to the fact that tolerance exists in the production process, the position between the two battery cells is narrow due to the fact that the heat insulation pad is assembled in the battery cells, the two battery cells can be subjected to larger force although the heat insulation pad can be assembled in the battery cells forcibly, if aerogel of the heat insulation pad expands due to heating, the outer shell of the battery cells is easy to deform and break, the battery cells are damaged, and the service life is short. Therefore, there is a need to propose a new solution to the above-mentioned problems.
Disclosure of Invention
In view of the above, the present utility model aims at overcoming the drawbacks of the prior art, and its main objective is to provide a buffer type heat insulation pad, which can effectively solve the problems that the conventional heat insulation pad cannot absorb the tolerance generated by the battery core, so that the battery core is subjected to a larger extrusion force for a long time, the battery core housing is easy to be deformed and broken by stress, and the battery core is damaged, and the service life is short.
In order to achieve the above purpose, the present utility model adopts the following technical scheme:
a buffer type heat insulation pad comprises aerogel and a buffer piece; a first double-sided adhesive tape is adhered to one surface of the aerogel; the buffer piece is attached to the other surface of the aerogel, and the second double-sided adhesive tape is attached to the surface of the buffer piece.
As a preferable scheme, two buffer parts are arranged, the two buffer parts are attached to the other surface of the aerogel, a buffer space is formed between the two buffer parts, and a certain space is provided for expansion of the battery cell.
As a preferable scheme, the first double-sided adhesive tape is provided with first release paper, and the first release paper is outwards extended to form a first easily torn position, so that the first release paper is easier to separate from the first double-sided adhesive tape.
As a preferable scheme, the second double-sided adhesive tape is provided with second release paper, and the second release paper is outwards extended to form a second easily torn position, so that the second release paper is easier to separate from the second double-sided adhesive tape.
As a preferable scheme, the buffer member is made of MPP foam.
Compared with the prior art, the utility model has obvious advantages and beneficial effects, and in particular, the technical scheme can be as follows:
through paste at another surface of aerogel and establish the bolster, the bolster itself possesses certain deformability, even if the position of assembling the heat insulating mattress is narrower between two electric cores, can guarantee still that after the heat insulating mattress is assembled into, electric core can not receive great power to absorb the produced tolerance of electric core, electric core also can not receive great extrusion force for a long time, and take place atress deformation, rupture, effectively protect electric core not damaged, extension electric core's life.
