Claims24
A rechargeable battery, comprising
- an electrode assembly including a positive electrode, a negative electrode, and a separator interposed between the positive electrode and the negative electrode;
- a case receiving the electrode assembly;
- an electrolyte solution injection member positioned at one side of the case and forming an injection hole;
- and
- a sealing member covering and sealing the injection hole.
A method for injecting an electrolyte solution into a rechargeable battery, comprising:
- preparing a rechargeable battery including an electrode assembly, a case receiving the electrode assembly, an electrolyte solution injection member positioned at one side of the case, and a sealing member sealing the electrolyte solution injection member;
- removing the sealing member of the rechargeable battery;
- connecting an electrolyte solution container with the electrolyte solution injection member of the rechargeable battery;
- injecting the electrolyte solution by using a difference in pressure between the rechargeable battery and the electrolyte solution container;
- and
- removing connection between the electrolyte solution container and the electrolyte solution injection member of the rechargeable battery.
A battery assembly comprising:
- an electrode assembly that generates electrical power and is rechargeable;
- a pouch-type casing formed of a polymer material, wherein the pouch type casing defines a space that receives the electrode assembly and an electrolyte and is sealable so that the space is sealed;
- an electrolyte injection and extraction member that is positioned in the pouch-type casing so as to allow electrolyte to be injected into and extracted from the space and wherein the electrolyte injection and extraction member is resealable following injection or extraction of the electrolyte,
- wherein the electrolyte injection and extraction member defines a sealable aperture that communicates between the exterior of the pouch-type casing and the interior space.
