Abstract:
Provided is an apparatus for evaluating high-temperature creep behavior of metals, the apparatus including a chamber configured to fix a metal sample in an inner space sealed from an external environment, and including, at a lower portion, a metal tube stretchable in a length direction by a pressure of a gas, wherein the apparatus is configured in such a manner that a load received by the chamber in the length direction due to the pressure of the gas injected into the chamber is applied to the metal sample.
Abstract:
Provided are a prelithiation method of a silicon-based active material, the prelithiation method including step S1 of immersing the silicon-based active material in a prelithiation solution including an organic solvent and a lithium-hydrocarbon molecule complex, step S2 of obtaining a powder by washing the silicon-based active material with the organic solvent and drying the silicon-based active material, and step S3 of performing a heat treatment on the powder at a temperature of 400° C. to 800° C. in an inert gas atmosphere, and a silicon-based active material prelithiated by the method.
Abstract:
A vanadium-based hydrogen permeation alloy for a membrane, a method of manufacturing the same, and a method of using a membrane including the same are provided. The vanadium-based hydrogen permeation alloy for a membrane includes nickel (Ni) at more than 0 atm % and 5 atm % or less, iron (Fe) at 5 atm % to 15 atm %, yttrium (Y) at more than 0 atm % and 1 atm % or less, and a remainder of vanadium and impurities.
