Abstract: The present disclosure discloses a method and an apparatus for generating a vector representation of a knowledge graph, and relates to a field of a field of artificial intelligence technologies. The detailed implementing solution is: obtaining a knowledge graph, the knowledge graph including a plurality of entity nodes; obtaining a context type and context data corresponding to the knowledge graph; and generating vector representations corresponding to the plurality of entity nodes by a context model based on the context data and the context type.

Abstract: The invention provides an electrode sheet, the surface of the active material layer of the electrode sheet is provided with an intermediate layer and a lithium-supplementing layer, the intermediate layer includes a solid electrolyte, and the lithium-supplementing layer includes a lithium-containing compound that self-decomposes to produce lithium ions. The electrode sheet of the present invention may effectively suppress the heat generated in the lithium supplementing process, and overcome the defect of continuous consumption of active lithium ions in the continuous growth of the SEI layer. Therefore, the electrode sheet provided by the present invention has excellent lithium supplementation effect and electrochemical performance.
