Problems solved by technology
[0004] Those skilled in the art can understand that during actual use, the heat accumulated in the core of the battery cell is the highest, and it is difficult for the battery cell to dissipate heat through its periphery, which will lead to a reduction in the service life of the battery cell, and will not Conducive to the efficient use of battery energy and improve the cruising range of the vehicle
However, the prior art WO2008 / 104374 does not disclose a heat conduction plate specially used for battery cells, especially designed to dissipate heat from the core of the battery cell. The geometric characteristics of the performance related to the effective heat dissipation of the core, so there is still room for heat conduction elements inside the battery cell

The invention relates to a battery monomer with a heat conduction structure. The battery monomer comprises a shell, an anode terminal and a cathode terminal, and at least two battery pieces positioned inside the shell, wherein each battery piece is connected with the anode terminal and the cathode terminal; the battery monomer further comprises at least one heat conduction element; the heat conduction element is arranged between the battery pieces; an insulating layer is arranged on the surface at which the heat conduction element is attached to the battery pieces so as to achieve electric insulation between the heat conduction element and the battery pieces. The invention further relates to a battery with the battery monomer and a vehicle with the battery. Compared with the prior art, the battery monomer can effectively conduct heat from the core of the battery, simplify the internal structure of the battery and remarkably prolong the service of the battery, so that the battery can work stably for a long time.
Description
technical field [0001] The invention belongs to the technical field of batteries, and in particular relates to a battery cell with a heat-conducting structure, a battery equipped with the battery cell, and a vehicle provided with the battery. Background technique [0002] At present, batteries are widely used in the field of automobiles, especially in the field of new energy electric vehicles. The main purpose of the battery is to meet the needs of driving electric vehicles. It is generally composed of several battery cells connected in series or in parallel. During the working process of the battery, the battery cell will generate a lot of heat. If the heat is not dissipated in time, it will have a certain impact on the life of the battery. Although many inventions have been made for the heat dissipation of the battery in the prior art, almost all heat conducting elements are arranged outside the battery cells. [0003] For example, in the patent document with the publica...
