Abstract: A lithium-ion battery conductive bonding agent, including graphene and a first bonding agent grafted on a surface of the graphene, a production method for the conductive bonding agent, and an electrode plate and a lithium-ion battery that contain the conductive bonding agent, where the first bonding agent includes at least one of polyvinyl alcohol, sodium carboxymethyl cellulose, polyethylene glycol, polylactic acid, polymethyl methacrylate, polystyrene, polyvinylidene fluoride, a hexafluoropropylene polymer, styrene-butadiene rubber, sodium alginate, starch, cyclodextrin, or polysaccharide. The lithium-ion battery conductive bonding agent has good conductive performance and bonding performance and specific strength, improving mechanical strength of a whole electrode plate. The conductive bonding agent integrates a bonding agent and a conductive agent. This can improve content of active substance in the electrode plate, and further increase an energy density of an electrochemical cell.

Abstract: A weight determining method and a related apparatus, to reduce a beam gain loss caused by a beam selection deviation are described. The method includes receiving an uplink reference signal and obtaining a channel reciprocity parameter between an uplink channel and a downlink channel based on the uplink reference signal. The method further includes determining state information of the downlink channel based on the channel reciprocity parameter, carrier frequency information of the uplink channel, and carrier frequency information of the downlink channel. Moreover, the method includes determining a weight of a downlink reference signal based on the state information of the downlink channel.

Abstract: The present invention disclose an information processing method and a mobile device. The mobile device includes a device body and a magnetic adjustment mechanism, where the magnetic adjustment mechanism includes a magnetic adjustment member and a magnetic sensor, and the magnetic adjustment member is adjusted to enable the magnetic sensor to generate a pulse signal; and the device body further includes a processor and a display screen, and the processor receives the pulse signal generated by the magnetic adjustment mechanism, processes the pulse signal, and then displays adjusted content by using the display screen. This avoids a problem that adjustment cannot be conveniently performed because a display screen is covered by a finger when an operation is performed directly on the display screen.
