An electrochromic device (100), and a preparation method and control method therefor. The electrochromic device (100) comprises a first electrode layer (1), a second electrode layer (2), a color-changing functional layer (3), and an intermediate layer (4, 16), wherein the second electrode layer (2) is arranged at one side of the first electrode layer (1) and is arranged opposite the first electrode layer (1); the color-changing functional layer (3) is arranged between the first electrode layer (1) and the second electrode layer (2); the intermediate layer (4, 16) is arranged between the first electrode layer (1) and the second electrode layer (2); and the intermediate layer (4, 16) is configured to capture at least some electron charges transmitted between the electrode layers (1, 2) and the color-changing functional layer (3), or, to deform in a pressed region when the electrochromic device (100) is pressed, thereby realizing color rendering or discoloration at the position where the deformation occurs.
