Abstract: Disclosed by the present application are a method and device in a node used for wireless communication. A first node receives first information and receives first signaling. The first information comprises K pieces of configuration information which are for a first service cell; a first configuration information set comprises K1 pieces of configuration information among the K pieces of configuration information; the first signaling is used for activating K2 pieces of configuration information in the first configuration information set and indicating that only the K2 pieces of configuration information in the first configuration information set are in an active state. K is a positive integer greater than one, K1 is a positive integer greater than one and less than K, and K2 is a positive integer less than K1. When a UE is configured by a plurality of configured grant configurations, the described method reduces the signaling overhead required to activate/release said configurations.

Abstract: A three-dimensionally ordered macroporous (3DOM) metal-organic framework material (MOF)-based quasi-solid-state electrolyte thin film for a safe quasi-solid-state lithium secondary battery are involved in present invention. In detail, the above quasi-solid-state electrolyte combines 3DOM-MOFs and the electrolytes like polymer and traditional liquid electrolyte. The special pore structures in 3DOM-MOFs could both fill the polymer electrolyte and liquid electrolyte with macropores and micropores, respectively. This unique structure could significantly enhance the Li  +  conductivity rate through the different kinds of electrolytes in the corresponding pore structures as well as improves the battery performance. More importantly, this quasi-solid-state electrolyte is much safer than the traditional organic electrolyte. It should be easily to scale-up since the procedures are simple.

Abstract: The present invention provides a novel safety aluminum-plastic film. The aluminum-plastic film is a soft package structure of a lithium battery, and comprises an outer protective layer, a middle aluminum foil layer, and an inner heat seal layer that are successively stacked. The inner heat seal layer comprises an adhesive MPP layer, a PP layer, and a heat seal PP layer that are successively stacked; moreover, the side close to the lithium battery is a single-layer heat seal PP layer, the side away from the lithium battery is the adhesive MPP layer, and the heat seal PP layer is a low-melting-point PP layer. The melting point of a technically modified heat seal PP material is within 100-110°C; when a heating temperature reaches 100-140°C, the heat seal strength is within 2-100 N, which is much lower than the heat seal strength (80-120 N) of conventional heat seal materials, such that the soft package of the lithium battery is easily opened by the impact of internal gas at a high temperature, and thus excessively high temperature inside the lithium battery can be avoided so as to prevent fire.
