ELECTRODE ASSEMBLY, MANUFACTURING METHOD THEREFOR, BATTERY CELL, BATTERY, AND ELECTRIC APPARATUS

This application relates to the field of batteries, and in particular, to an electrode assembly (201) and a manufacturing method therefor, a battery cell (20), a battery (10), and an electric apparatus (100). The electrode assembly (201) includes: a first electrode plate (1), being folded back and forth in a first direction (X) so that the first electrode plate (1) includes a plurality of first laminates (11) connected and stacked in sequence; and a second electrode plate (2), being opposite the first electrode plate (1) in polarity and being folded once in a second direction (Y) so that the second electrode plate (2) includes two second laminates (21) connected to each other, where the second direction (Y) is perpendicular or parallel to the first direction (X), and the second laminates (21) and the first laminates (11) are alternately stacked in sequence. Based on this, the production efficiency of the stacked batteries can be effectively improved.
