Abstract
The utility model discloses a unit cell with polar columns with the functions of liquid injecting and gas exhausting. The unit cell comprises a cell case and an electrode panel, wherein two bases are arranged at two ends of the electrode panel respectively; the two polar columns are respectively arranged on the bases; a through groove adopting a stepped structure is arranged in each polar column; the diameter of the outside grooves of the through grooves is greater than that of the inside grooves of the through grooves; a plug is arranged in the outside groove of each through groove and seals the outside groove; the external threads of the plugs are matched with the internal threads of the outside grooves of the through grooves; an inner hexagonal hole is formed in the bare face of each plug. In order to facilitate liquid injecting and gas exhausting, holes are formed in the middles of the polar columns of the unit cell; the through grooves are designed to be step-shaped, so that the plugs can be conveniently arranged in the outside grooves of the through grooves, and are prevented from falling to the through grooves while the polar columns are sealed; the plugs can be removed, liquid injecting holes are formed or gas can be discharged at any time when gas in the unit cell increases continuously, as a result, potential safety hazards are eliminated.
Description
Technical field
The utility model relates to cell technical field, more specifically says that a kind of pole has the cell of fluid injection and degassing function.
Background technology
Cell, form elementary cell by electrode and electrolyte, in electrolyte chemical reaction discharge process, there are the gas of generation and rising temperature, can be received under normal circumstances, but the in the situation that of the chance failures such as internal short-circuit, can discharge a large amount of gas and amount of heat, so that the cell internal gas of sealed environment expands and temperature raises, and when serious, can produce explosion accident.
Therefore cell can arrange a bleeder port in the middle of electrode panel, and a slice rupture pressure disc is set in bleeder port, lose heart thereby can burst to a certain extent rupture pressure disc when gas expansion, and prevent exploding accident.Once setting completed for this rupture pressure disc, just be not easy to start to discharge the gas producing in cell under normality, can not be used for fluid injection simultaneously, fluid injection need to arrange in addition a liquid injection hole on electrode panel, but cell is in the time that activation changes into, liquid injection hole can opening, and extraneous air easily enters cell inside from this, thereby affect battery performance, have potential safety hazard.
Utility model content
The purpose of this utility model is to overcome the above defect of prior art, provides a kind of rational in infrastructure, safe and reliable, convenient and practical pole to have the cell of fluid injection and degassing function.
In order to reach above object, the utility model is achieved through the following technical solutions: a kind of pole has the cell of fluid injection and degassing function, comprise battery container and electrode panel, on the two ends of described electrode panel, be respectively arranged with a pedestal, on each pedestal, be provided with a pole, it is characterized in that, described pole hollow is provided with the through slot of a step structure, the outer side slot footpath of described through slot is greater than inner side slot footpath, in the outer side slot of described through slot, capping has an obstruction, described obstruction matches with internal thread in the outer side slot of its external screw thread and described through slot, on the exposed end face of described obstruction, be provided with an inner hexagonal hole.
In order to facilitate fluid injection and exhaust, the utility model is by punching in the middle of the pole of cell, and through slot design is become stepped, be convenient to arrange daily obstruction in outer side slot, when sealing pole, also play and prevent from stopping up the effect of falling into, obstruction is opened and be can be used as liquid injection hole, also can constantly increase and discharge at any time according to the gas of cell inside, eliminates safe hidden trouble.
As preferably, between described obstruction and the cascaded surface of described through slot, be provided with a reinforcement pad.
As preferably, between described reinforcement pad and the cascaded surface of described through slot, be provided with a sealing ring.
The effect of strengthening pad and sealing ring is the sealing property increasing after pole perforate.
