Abstract: Embodiments of the present invention provide a communication establishment method. The method includes: receiving, by a first terminal, a first broadcast message of a first wireless communications mode sent by a second terminal, where the first broadcast message carries a second wireless communications mode supported by the second terminal and a status and/or supported protocol information of the second wireless communications mode; and determining, by the first terminal based on the second wireless communications mode supported by the second terminal and the status and/or the supported protocol information of the second wireless communications mode, whether to connect to the second terminal.

Abstract: A first device obtains an advertising parameter used by a second device to send an advertising data packet, where the advertising parameter includes an advertising window and an advertising interval. The first device determines, based on the advertising window and the advertising interval by using a preset scanning model, a target scan parameter used by the first device, where the target scan parameter is a scan parameter used by the first device when power consumption of the first device is a preset threshold and a scan-to-discover time period satisfies a preset condition. The target scan parameter includes a target scan window and a target scan interval. The first device performs scanning based on the target scan window and the target scan interval.

Abstract: Embodiments of the present disclosure provide a cathode active material for a lithium-ion secondary battery, where the cathode active material for a lithium-ion secondary battery includes a silicon-based active substance and a nitrogen-doped carbon material. The silicon-based active substance is encased in the interior of the nitrogen-doped carbon material, and the silicon-based active substance is one or more of a nanoparticle and a nanowire; a micropore is arranged on at least one of the exterior and the interior of the nitrogen-doped carbon material; and a material of the nitrogen-doped carbon material is a nitrogen-doped carbon network. The cathode active material for a lithium-ion secondary battery solves a problem in the prior art that a silicon material, when used as a cathode active material, easily falls from a current collector due to a great volume change and has a low conductivity.
