Abstract: The disclosure discloses a method for preparing a high-voltage cathode material by body modification and regeneration of a waste lithium cobaltate material. The waste lithium cobaltate cathode material is calcined, and then measured; a lithium source, a magnesium source, nano-scale TiO2 and the waste lithium cobaltate cathode material powder are mixed to obtain a mixture, placed in a ball milling tank containing absolute ethanol, and the resulting mixture is ball milled, and then dried to obtain a mixed powder; the mixed powder is calcined to obtain a magnesium-titanium co-doped regenerated lithium cobaltate cathode material; the magnesium-titanium co-doped regenerated lithium cobaltate cathode material is added into a mixed solution obtained by ultrasonically mixing absolute ethanol with the aluminum source, and then heated and stirred continually until the solvent evaporates to obtain a residue; the residue is calcined to obtain an aluminum-coated magnesium-titanium co-doped regenerated lithium cobaltate cathode material.

Abstract: A method and a system for identifying a glacial lake outburst debris flow (GLODF) are provided. The method is obtained based on considering induced influences of slopes of channels and particle sizes of source particles on the GLODF. The method not only compensates for deficiencies in identifying the GLODF, but also realizes determination of the GLODF, which provides data basis for disaster prevention and control layout such as monitoring and early warning on a glacial lake and assists preventing and managing disasters caused by the GLODF. Meanwhile, multiple parameters used in the method are easy and convenient to obtain, and the parameters can be directly used on site, which saves engineering cost, improves working efficiency, and has high practical and promotional value in environmental protection and disaster prevention and mitigation.
