Abstract: The present invention provides: a method for preparing a petcoke-based artificial graphite negative electrode material for a lithium secondary battery, in which low-grade petcoke is used as a raw material, and artificial graphite having a high degree of graphitization is prepared through leaching and acid treatment of pulverized/classified low-grade petcoke in an acidic solution, followed by carbonization and graphitization; an artificial graphite negative electrode material for a lithium secondary battery, prepared thereby; and a lithium secondary battery.

Abstract: A silicone pressure-sensitive adhesive composition is disclosed. The composition can be cured into a pressure-sensitive adhesive having a good release force against a release liner and a high peel force against several substrates. The silicone pressure-sensitive adhesive composition comprises: (A) a diorganopolysiloxane having on average at least 0.5 alkenyl groups with 2 to 12 carbon atoms per molecule; (B) an organopolysiloxane composed of R13SiO1/2 and SiO4/2 units, wherein each R1 represents a monovalent hydrocarbon group with 1 to 12 carbon atoms, having a molar ratio (R13SiO1/2 unit)/(SiO4/2 unit) of 0.6 to 1.7, and having a number average molecular weight (Mn) converted to standard polystyrene of from 1,700 to 3,000; (C) an organohydrogenpolysiloxane having on average at least two silicon-bonded hydrogen atoms per molecule; and (D) a hydrosilylation catalyst.
