This invention discloses a modified polymethylhydrosiloxane electrolyte additive, its preparation method, electrolyte, and applications, belonging to the field of lithium metal batteries. The additive of this invention has a siloxane main chain, with at least one of carbonate and fluoroalkane substituents and an ether substituent introduced into the side chain. This allows the modified polymethylhydrosiloxane, when used as an electrolyte additive, to effectively reduce side reactions between lithium metal and the electrolyte, inhibit lithium dendrite growth, and maintain the crystal structure of the high-nickel cathode, reducing its disintegration and nickel ion deposition. When compounded with carbonate organic solvents as an electrolyte and applied to lithium metal batteries, it effectively improves the cycle stability and coulombic efficiency of lithium metal batteries.

The present application discloses a method, device, equipment and medium for building entity edges in a knowledge graph, which belongs to the field of artificial intelligence. The method includes: obtaining a target binary relationship of a first entity, the target binary relationship includes a first entity, a target attribute and a second entity, and the second entity is an attribute value of the first entity in the target attribute; based on the target attribute, determining a second entity node corresponding to the second entity in the knowledge graph; in the knowledge graph, building edges between the first entity node corresponding to the first entity and the second entity node. The above scheme overcomes the problem of being unable to capture jump links that may be caused when the data of the knowledge graph comes from different external data sources, thereby improving the connectivity rate of the knowledge graph.
