Disclosed is a method for measuring cell performance. The method for manufacturing performance of a unit cell, in which a first electrode provided with a first electrode tab, a separator, and a second electrode provided with a second electrode tab are alternately laminated to be bonded to each other, comprises an additional lamination step of further laminating counter electrodes, each of which has the same polarity as that of the second electrode and is provided with a third electrode tab, on sides facing the first electrode at the outermost sides of the unit cell with the separator therebetween, and an outer interface analysis step of measuring a different in performance between the first electrode and each of the counter electrodes by electrically connecting the first electrode tab disposed on the first electrode to the third electrode tab disposed on the counter electrode.

Method for measuring cell performance

The present invention provides a lithium secondary battery which includes a positive electrode including a first lithium cobalt oxide and a second lithium cobalt oxide which have different average particle diameters (D) from each other, a negative electrode including first graphite and second graphite which have different average particle diameters (D) from each other, and an electrolyte including a a first additive as a nitrile-based compound, wherein the first lithium cobalt oxide and the second lithium cobalt oxide each independently contain aluminum in a concentration of 2,500 ppm to 4,000 ppm.

Lithium secondary battery

The invented inositol and trehalose derivatives, prepared by introducing multiple units of the guanidine group to the backbone molecules, show excellent blood-brain barrier permeability, and accordingly, it can be easily transported to the brain tissues and utilized for the treatment of neurodegenerative diseases such as Alzheimer's disease and Huntington's disease.
