摘要： The cathode active material for a lithium secondary battery according to embodiments of the present invention includes lithium-transition metal composite oxide particles including a plurality of primary particles, and the lithium-transition metal composite oxide particles have a lithium-potassium-containing portion formed between the primary particles. Thereby, it is possible to improve life-span properties and capacity properties by preventing the layer structure deformation of the primary particles and removing residual lithium.

摘要： The present invention relates to a method for producing anhydrosugar alcohol using an organic additive having one hydroxyl group. The present invention makes it possible to prevent oligomers and polymers from being produced by polymerization of isosorbide during dehydration of sorbitol molecules, and thus solves problems, including a reduction in fluidity in a dehydration reactor, interference with the flow of fluids in the reactor and pipelines, and interference with stirrer operation, which occur due to the oligomers and polymers.
