NOVELTY - A lithium secondary battery comprises nonaqueous electrolyte solution which consists of nonaqueous solvent which dissolves positive electrode which can occlude and release lithium, negative electrode and lithium salt (preferably hexafluorophosphate lithium). The lithium secondary battery is obtained by differentiating first degree of phosphorus X-ray absorption near edge structure spectrum inside positive electrode surface vicinity which is removed from the battery and positive electrode.    USE - Lithium secondary battery for notebook personal computer, pen input personal computer, mobile personal computer, electronic book player, mobile telephone, portable fax, portable copy, portable printer, headphones stereo, video movie, liquid crystal television, handy cleaner, portable compact disk, minidisk, transceiver, electronic notebook, calculator, memory card, portable tape recorder, radio, backup power supply, motor, luminaire, toy, game machine device, timepiece, electronic flash, camera and motive power source for motor vehicles.    ADVANTAGE - The cycling characteristics at high voltage charging/discharging and low temperature characteristic can be improved.    DETAILED DESCRIPTION - The lithium secondary battery comprises nonaqueous electrolyte solution which consists of nonaqueous solvent which dissolves positive electrode which can occlude and release lithium, negative electrode and lithium salt (preferably hexafluorophosphate lithium). The lithium secondary battery is obtained by differentiating first degree of phosphorus X-ray absorption near edge structure spectrum inside positive electrode surface vicinity which is removed from the battery and positive electrode which has first peak intensity of 2150-2154 eV (a'), second peak intensity of 2154-2160 eV (b') and ratio of (a/b)/(a'/b') is greater than or equal to 0.5. INDEPENDENT CLAIMS are included for:    (1) a manufacture of positive electrode; and    (2) a positive electrode.    DESCRIPTION OF DRAWING(S) - The drawing shows a graph of the phosphorus absorption edge X-ray absorption fine structure differential spectrum on the surface of the sample.
