Abstract
The invention discloses a tank structure of a lithium iron phosphate battery. The tank structure consists of a tank body and a cover, wherein the cover seals the tank body; the outer wall of the tank body is provided with an explosion-proof groove formed by a groove; and the groove is parallel to the axial direction of the tank body. The outer wall of the tank body is provided with the explosion-proof groove, so when the pressure in the tank body is greater than a certain value, the tank body can leak air from the explosion-proof groove to prevent explosion danger caused by overhigh pressure in the tank body.
Description
Technical field:
The present invention relates to electricity field, relate in particular to chemical cell, particularly a kind of tank structure of ferric phosphate lithium cell.
Background technology:
In the prior art, the size of ferric phosphate lithium cell is less, and the monomer finite capacity is with regard to needs many battery cells in parallel, therefore inapplicable in the big field of capacity requirement such as electric automobile in the time of will satisfying the larger capacity requirement.The volume that increases ferric phosphate lithium cell can increase the monomer capacity, and still, large volume cell tank body internal pressure is big, blasts easily, and fail safe is undesirable.
Summary of the invention:
The object of the present invention is to provide a kind of tank structure of ferric phosphate lithium cell, the tank structure of described this ferric phosphate lithium cell will solve the technical problem that has risk of explosion after the ferric phosphate lithium cell volume increases in the prior art.
The tank structure of this ferric phosphate lithium cell of the present invention is made of tank body and lid, and described lid is sealed on the tank body, and wherein, the outer wall of described tank body is provided with an explosion-proof groove, and described explosion-proof groove is made of a groove.
Further, described groove is parallel to the axial of tank body.
Further, be provided with electrode and electrolyte in the described tank body, described electrolyte is gel state.
Operation principle of the present invention is: the outer wall of tank body is provided with explosion-proof groove, and when tank body internal pressure during greater than certain value, tank body can at first lose heart from explosion-proof groove, to prevent the excessive explosion hazard that causes of tank body internal pressure.
The present invention compares with prior art, and its effect is actively with tangible.The outer wall of the present invention's ferric phosphate lithium cell tank body is provided with explosion-proof groove, and when tank body internal pressure during greater than certain value, tank body can at first lose heart from explosion-proof groove, to prevent the excessive explosion hazard that causes of tank body internal pressure.
Description of drawings:
Fig. 1 is the schematic diagram of the tank structure of ferric phosphate lithium cell of the present invention.
Embodiment:
Embodiment 1:
As shown in Figure 1, the tank structure of ferric phosphate lithium cell of the present invention is made of tank body 1 and lid 2, and described lid 2 is sealed on the tank body 1, and wherein, the outer wall of described tank body 1 is provided with an explosion-proof groove 3, and described explosion-proof groove 3 is made of a groove.
Further, described groove is parallel to the axial of tank body 1.
Further, the cross section of described groove is V-shaped.
Further, be provided with electrode and electrolyte in the described tank body 1, described electrolyte is gel state.
The operation principle of present embodiment is: the outer wall of tank body 1 is provided with explosion-proof groove 3, and when tank body 1 internal pressure during greater than certain value, tank body 1 can at first lose heart from explosion-proof groove 3, to prevent the excessive explosion hazard that causes of tank body 1 internal pressure.
