- the present invention relates to a battery including a gas discharge member and an electrolyte pouring member.
- a secondary battery is composed of an electrode assembly composed of a positive electrode, a negative electrode, and a separator interposed between the positive electrode and the negative electrode, embedded in a battery case of a metal can or laminate sheet, and then injected or impregnated with an electrolyte solution.
- the pouch type secondary battery has a vacuum sealing applied to minimize the contact between the internal battery cells and the outside air, which makes it practically impossible to discharge the injection of the additional electrolyte and the generated gas to the outside.
- the present invention aims to solve the problems of the prior art as described above and the technical problems that have been requested from the past.
- An object of the present invention is to provide a battery which can further inject an electrolytic solution and can easily discharge the generated gas to the outside.

- the gas discharge member may include a tubular member communicating with the internal space and a liquid material impermeable porous membrane mounted to one end of the tubular member.
- the pore size may be in the range of 0.1 nm or more to 1 nm or less. If the pore size is less than 0.1 nm, the gas may not be discharged smoothly. On the other hand, when the pore size exceeds 1 nm, the problem of permeation of the liquid electrolyte may occur. Thus, the appropriate pore size of the porous membrane may be in the above range.
- the gas discharge member may further include a suction member mounted at the other end of the tubular member.
- the suction member may be a suction pump.
- the liquid electrolyte pouring member may include a tubular member communicating with the internal space and a liquid electrolyte storage tank mounted at one end of the tubular member.
- the liquid electrolyte pouring member may further include a backflow preventing member mounted at the other end of the tubular member.
- the backflow preventing member may be a check valve.
- the check valve is fixed to a center pin, a first valve having a through hole through which a liquid electrolyte and a hollow through which the center pin passes, and a first valve coupled to one end of the center pin and being connected to the first valve. It may include a second valve to be coupled or separated to open and close the tubular member, and an elastic member for inducing a coupling state of the first valve and the second valve.
- the elastic member may be composed of a compression spring.
- the cell includes a space portion in which the electrode stack and the electrolyte are embedded, and a seal surrounding the space portion, wherein the seal is formed with a through hole coupled with a through member of the liquid electrolyte injection member and a through member of the gas discharge member. It may be a pouch type cell.
- the through hole may further include a backflow prevention member mounted at one end.
- the present invention also provides a battery module including the battery as a unit cell.
- the present invention also provides a battery pack including the battery module as a unit module.
- the present invention also provides a device comprising the battery pack as a power source, and the device is specifically, a mobile phone, a portable computer, a smartphone, a smart pad, a netbook, a LEV (Light Electronic Vehicle), an electric vehicle. , A hybrid electric vehicle, a plug-in hybrid electric vehicle, and a power storage device.

- FIG. 1 is a schematic view of a battery according to an embodiment of the present invention.
- FIG. 1 is a schematic diagram of a battery according to an embodiment of the present invention.
- the battery 10 includes a cell 100, a gas discharge member 200, and a liquid electrolyte injection member 300.
- the gas discharge member 200 includes a tubular member 210, a liquid material impermeable porous membrane 220, and an intake pump 230.
- the gas generated in the cell 100 is discharged to the outside of the cell through the tubular member 210 by the intake pump 230 of the gas discharge member 200.
