Abstract: In some implementations, a computing device may perform a method for providing a unified pipeline for media metadata to converge disparate schemas and data structures into a global unified graph. The method includes receiving media metadata from disparate media sources that may each have a different metadata schema that defines the structure and attributes of the metadata provided by each media source. The computing device may compare media metadata received from the different media sources to determine that metadata received from the different media sources correspond to similar, or the same, media entities (e.g., songs, movies, books, etc.). The metadata for the similar media entities may then be combined into a global unified graph that may include metadata attributes and/or values of the metadata received from the various media sources.

Abstract: The present invention provides a lithium ion battery and a negative electrode material thereof. The negative electrode material includes a mixture of a graphite and an amorphous carbon, wherein the graphite is subjected to a surface treatment, and the surface treatment manner is a combination of mechanical fusion modification and spray drying coating, and wherein the graphite has a graphitization degree of 90-96%, an average particle diameter D50 of 13-25 ?m and a specific surface area BET of 0.8-2.5 m2/g, and the amorphous carbon has a graphitization degree of 65-80%, an average particle diameter D50 of 2-15 ?m and a specific surface area BET of 1.0-3.0 m2/g.

Abstract: The present invention provides a lithium ion battery and a negative electrode material thereof. The negative electrode material includes a graphite and an amorphous carbon, wherein the graphite has a graphitization degree of 90˜96% and an average particle diameter D50 of 2˜25 ?m, and the amorphous carbon has a graphitization degree of 65˜80% and an average particle diameter D50 of 2˜25 ?m. Compared with the prior art, by mixing graphite having a small particle diameter with amorphous carbon, the negative electrode material of the present invention has excellent dynamic performance, cycle performance and storage performance. The present invention also provides a lithium ion battery.
