Abstract
An embodiment of the present application provide an electrode assembly, a battery cell, a battery, and an electrode assembly manufacturing equipment and method. Among that, the electrode assembly includes a negative electrode plate and a positive electrode plate which form a bending region. The positive electrode plate includes bending portions located in the bending region, the bending portion includes a positive electrode current collecting layer and a positive active substance layer, and at least one side surface of the positive electrode current collecting layer is provided with the positive active substance layer in a thickness direction of the positive electrode plate. At least one positive active substance layer is provided with the barrier layer, at least a part of the barrier layer is intercalated in the positive active substance layer provided with the barrier layer, and coats at least a part of particles in the positive active substance layer.
