Abstract: A screen sharing method and system and an electronic device are provided. The screen sharing system may include a first electronic device, a second electronic device, a third electronic device, and a fourth electronic device. The third electronic device may be an electronic device near the first electronic device. The fourth electronic device may be an electronic device near the second electronic device. In the method, the first electronic device may establish a video communication connection to the second electronic device. The third electronic device may share a screen of the third electronic device with the second electronic device by using the first electronic device. The second electronic device may display the screen shared by the third electronic device, and may further switch the screen shared by the third electronic device to the fourth electronic device for display.

Abstract: This application provides a service sharing method and system, and an electronic device. The method includes: A first device may display a chat interface with a first contact, where the chat interface includes an input box for a chat message. If it is detected that a user inputs a preset symbol into the input box, the first device displays a first device list. If it is detected that the user selects a second device from the first device list, the first device displays a service list provided by the second device, where the service list includes one or more services provided by the second device. If it is detected that the user selects a first service from the service list, the first device sends a first chat message in the chat interface, where the first chat message includes first service content corresponding to the first service selected by the user.

Abstract: A negative electrode current collector of a lithium metal battery includes a current collector substrate provided with a plurality of pore channels, a lithium dissolving agent filled in each of the pore channels of the current collector substrate, and a locking layer attached to a pore wall of a corresponding pore channel and located between the pore wall and the lithium dissolving agent. The lithium dissolving agent is a liquid or a gel capable of dissolving lithium metal. The locking layer is configured to constrain the lithium dissolving agent to the corresponding pore channel.
