Abstract: The present invention relates to a lithium composite oxide including a coating layer having a boron-containing oxide and a lithium secondary battery including the same. More particularly, the present invention relates to a lithium composite oxide improved in lifetime and capacity characteristics by inducing a predetermined correlation between the molar ratio of nickel in a lithium composite oxide including a coating layer having a boron-containing oxide and a full width at half-maximum (FWHM; deg., 2?) of a (104) peak among XRD peaks defined by the hexagonal lattice with an R-3m space group, and a lithium secondary battery including the same.

Abstract: The present invention relates to a positive electrode active material having improved electrical characteristics by adjusting an aspect ratio gradient of primary particles included in a secondary particle, a positive electrode including the positive electrode active material, and a lithium secondary battery using the positive electrode.

Abstract: The present invention relates to a UV curable water-based polyelectrolyte composition and a method for producing a polyelectrolyte film using the same, which provides a polyelectrolyte composition comprising: at least one polyelectrolyte selected from Formulas 1 to 3; an acrylate-based material; a cross-linker; a photoinitiator; and a solvent.

Abstract: The system for providing information on the current state of business of the local goods or services provider comprises: a power consumption information collection unit for collecting power consumption information of the local goods or services provider; a power consumption information analysis unit for analyzing the power consumption information, and extracting a feature of an amount of power consumption of the local goods or services provider; and a business open-or-closed determination unit for determining whether the local goods or services provider is open for business at a predetermined point in time, on the basis of the feature of the amount of power consumption of the local goods or services provider, and providing information on whether the local goods or services provider is open for business.
