Abstract: An electrode material layer includes an electrode active material and graphene of a sheet-like structure, a surface of the graphene is modified with magnetic response nanodots, and in the graphene, more than 50% of the graphene is arranged at an angle of 45° to 90° with respect to a surface, of the current collector, on which the electrode material layer is disposed, to form a heat conduction path having a specific orientation.

Abstract: The disclosure provides trusted user interface display methods. One example method applied to an electronic device having a foldable screen, includes: changing the foldable screen from a first display status to a second display status in response to a first operation performed by a user on the electronic device; displaying a user interface (UI) of a client application (CA) on a screen corresponding to the second display status; and triggering to display a trusted user interface (TUI) corresponding to the CA on the screen corresponding to the second display status in response to a second operation performed by the user on the UI of the CA, where the TUI is adapted to the screen corresponding to the second display status.
