摘要： A battery includes an electrode assembly including a positive electrode plate, a negative electrode plate, and a separator disposed between the positive electrode plate and the negative electrode plate. A first adhesive layer is provided between the positive electrode plate and the separator, and a second adhesive layer is provided between the negative electrode plate and the separator. A coating weight of the first adhesive layer is smaller than a coating weight of the second adhesive layer, and a total of the coating weight of the first adhesive layer and the coating weight of the second adhesive layer is more than or equal to 0.03 g/m2 and less than or equal to 0.15 g/m2.
