Abstract:
This application provides an electrode sheet and an electrochemical device. The electrode sheet includes a current collector and a functional coating located on at least one surface of the current collector. The functional coating includes a first coating, a second coating and an active material layer that are sequentially stacked on a surface of the current collector. The first coating includes a conductive agent, a binder and a first functional filler, and the second coating includes a conductive agent, a binder and a second functional filler. A mass ratio of the binder in the first coating to the first coating is a1, a mass ratio of the binder in the second coating to the second coating is a2, and a mass ratio of the binder in the active material layer to the active material layer is a3, and a1>a2>a3.
