A positive electrode material, a positive electrode including the same, a lithium battery including the same, and a method of preparing the same are disclosed herein. In some embodiments, a method of preparing a positive electrode active material including forming a first coating layer on a surface of a lithium transition metal oxide represented by Formula 1 using a basic aqueous solution containing a coating element M(where Mincludes at least one selected from sodium (Na) and aluminum (Al)), dry-mixing the lithium transition metal oxide having the first coating layer formed on a surface thereof, and a raw material containing a coating element M(where Mincludes boron (B)) and heat treating the mixture to form a second coating layer.

Method for preparing positive electrode active material for lithium secondary battery and positive electrode active material prepared thereby

Provided is a lithium secondary battery which includes a positive electrode, a negative electrode, a separator interposed between the positive electrode and the negative electrode, and an electrolyte, wherein the positive electrode includes a lithium composite transition metal oxide powder having a layered structure and a nickel content accounting for 85 atm % or more of total transition metals, and wherein the lithium composite transition metal oxide powder undergoes a 3% or less change in lithium-oxygen (Li—O) interlayer spacing in a state-of-charge (SOC) range of 58% to 72%.

Positive electrode active material for lithium secondary battery and lithium secondary battery

Provided are a cosmetic composition for anti-aging or alleviating skin redness, and a medicinal composition for treating and preventing skin inflammatory diseases caused by light, containing a compound inducing an increase in expression of adiponectin or a pharmaceutically acceptable salt thereof.

Cosmetic composition for anti-aging or alleviating skin redness, and medicinal composition for preventing and treating skin inflammatory diseases, containing compound inducing increase in expression of adiponectin

Provided are a composition having anti-oxidant, anti-aging, and autophagy activities to thereby be useful for preventing, alleviating, or treating age-related metabolic diseases including neurodegenerative diseases or type 2 diabetes, and uses thereof.
