Battery cell with overlap between insulator and connector, battery, and electronic device

A battery, comprising a battery cell;

• the battery cell comprises a battery cell body;
• a first tab and a second tab are provided on the battery cell body;
• the battery cell body is formed by winding an electrode assembly formed by stacking a first electrode plate and a second electrode plate;
• a tail end of the electrode assembly is a free end;
• a separator is provided between the first electrode plate and the second electrode plate;
• the first electrode plate comprises a first current collector and a first active substance layer:
• the battery cell further comprises a first connector, a first insulator, and a second insulator;
• wherein,
• the first connector is provided in a length direction of the battery cell body;
• wherein the first tab and the second tab extend out of the battery cell body along the length direction of the battery cell body;
• the first connector fastens the tail end of the electrode assembly to an outer surface of the battery cell body;
• the first tab is connected to the first electrode plate and the second tab is connected to the second electrode plate;
• the first tab and the second tab have opposite polarities;
• a first end of the first insulator is provided on the battery cell body;
• a second end of the first insulator covers a part of the first tab;
• a first end of the second insulator is provided on the battery cell body;
• a second end of the second insulator covers a part of the second tab;
• and
• viewed along a thickness direction of the battery cell body, at least a part of the first insulator does not overlap with the first connector in a direction perpendicular to the length direction of the battery cell body.
