Abstract: An electrode with coating layer and a Li-ion battery including the electrode with coating layer are provided. The electrode with coating layer includes an electrode piece, a first material layer adjacent to the electrode piece, and a second material layer adjacent to the first material layer and far away from the electrode piece, the first material layer includes a first inorganic particle and a first binder, the second material layer includes a second binder, the first inorganic particle is at least one selected from a group consisting of metal hydroxide and boron-containing compound. The electrode with coating layer, under synergistic effect of the first material layer and the second material layer, can improve thermal stability and safety of the battery, under a situation that both the exterior and interior of the battery are at high temperature, the battery does not readily burn or explode.
