Abstract

This application provides an electrode assembly and a manufacturing method thereof, a battery cell, a battery, and an electric apparatus. The electrode assembly includes a first electrode plate, and separators provided on two sides of the first electrode plate in a thickness direction of the electrode plate and stacked with the first electrode plate; where in an unfolded state of the electrode assembly, the separator has first edge portions each exceeding an end of the first electrode plate in a length direction of the separator, and the separator has second edge portions each exceeding an end of the first electrode plate in a height direction of the separator; and in the thickness direction of the electrode plate, the corresponding first edge portions on two sides of the first electrode plate are at least partly hot-melt connected to form first hot-melted segments, and the corresponding second edge portions on two sides of the first electrode plate are at least partly hot-melt connected to form second hot-melted segments. The technical solution in this application can enhance the electrochemical performance of batteries and improve the safety and reliability of batteries.
