  "textContent": "This application discloses a battery cell, a battery, and an electric apparatus. The battery cell in the embodiments of this application includes a housing, an electrode assembly, and a sealing member. The housing is provided with an electrolyte injection hole for injecting an electrolyte. The electrode assembly is accommodated in the housing. The sealing member includes a main body portion, a transition portion surrounding an outer side of the main body portion, and a connecting portion surrounding an outer side of the transition portion. The connecting portion is located on a side of the housing back away from the electrode assembly, at least part of the main body portion protrudes from a first surface of the connecting portion facing the housing and is accommodated in the electrolyte injection hole, and the connecting portion is connected to the housing to seal the electrolyte injection hole. A side of the transition portion facing the housing is provided with an avoidance groove, the avoidance groove is recessed relative to the first surface and surrounds the main body portion, and a groove wall surface of the avoidance groove is connected to the first surface and a surface of the main body portion; and a side of the main body portion back away from the electrolyte injection hole is provided with a recess. The embodiments of this application can improve the airtightness of the electrolyte injection hole, improving the safety.",
