  • Publication number: 20240067567
    Abstract: An alumina-based ceramic tool material with low thermal expansion and a preparation process thereof, accordingly, the ceramic tool material may have both the high hardness of alumina ceramics after the hot pressing sintering, and reduces the thermal expansion coefficient of the overall ceramic material by adding the Sc2W3O12 as the negative thermal expansion phase, which improves the thermal shock resistance of ceramic tools in high-speed cutting engineering and meets the requirements of large temperature range during the machining of nickel-based superalloys. Moreover, the composite material does not use metal binder and has strong thermal stability even in the high-speed machining under extreme heat-force-chemistry coupling, so it has a high machining compatibility for nickel-based superalloys.

  • Publication number: 20230207816
    Abstract: The present disclosure discloses a composite binder for a self-extinguishing lithium ion battery and a lithium ion battery. The composite binder is obtained by adding ammonium polyphosphate and polyacrylic acid into a solvent to prepare a mixed solution and then carrying out thermal treatment on the above mixed solution. The present disclosure combines the flame retardancy of ammonium polyphosphate with the feature of polyacrylic acid to inhibit volume expansion, so that a stable solid electrolyte interface (SEI) film is formed on the surface of the prepared lithium ion battery during the cycling, thereby significantly promoting the electrochemical performance of the lithium ion battery while improving the flame retardancy of the battery; besides, ammonium polyphosphate and polyacrylic acid can be crosslinked after being heated due to the interaction of hydrogen bonds to form a three-dimensional network structure, which significantly improves the structural stability of the battery.
