Zusammenfassung:	Provided in the embodiment of the present application are an electrode assembly, a battery cell, a battery, and an electric apparatus. The electrode assembly includes a positive electrode plate, a negative electrode plate, and a separation assembly The separation assembly is configured to separate the positive electrode plate from the negative electrode plate. The separation assembly includes a substrate area and a reinforcing area connected to the substrate area. A thickness of the reinforcing area is greater than a thickness of the substrate area. At least part of the reinforcing area is located between the positive electrode plate and negative electrode plate adjacent to each other. The reinforcing area may be configured to correspond to a position where the negative electrode plate is prone to lithium precipitation.
