摘要： Provided are an electrode assembly (10), a battery cell (6), a battery (2), and an electric apparatus. The electrode assembly (10) comprises a positive electrode plate (11), a negative electrode plate (12), and a separation assembly (13), and the separation assembly (13) is configured to separate the positive electrode plate (11) from the negative electrode plate (12). At least part of the separation assembly (13) is provided as a multi-layer structure area (13a), and at least part of the multi-layer structure area (13a) is located between the positive electrode plate (11) and negative electrode plate (12) adjacent to each other. The multi-layer structure area (13a) is configured to correspond to a position where the negative electrode plate (12) is prone to lithium precipitation. The multi-layer structure area (13a) can block lithium dendrites, thereby reducing the probability of conduction between the positive electrode plate (11) and the negative electrode plate (12), effectively reducing the risk of short circuiting, prolonging the service life of the electrode assembly (10), and improving the safety of the electrode assembly (10).
