摘要： A positive electrode active material having a lithium-excess lithium-transition metal composite oxide particle represented by the chemical formula Li1.2Mn0.54Ni0.13Co0.13O2. The lithium-excess lithium-transition metal composite oxide particle has an inner portion (1) having a layered structure and a surface adjacent portion (2) having a crystal structure gradually changing from a layered structure to a spinel structure from the inner portion (1) toward the outermost surface portion (3). The layered structure and the spinel structure have an identical ratio of the amount of Mn and the total amount of Ni and Co.

摘要： A non-aqueous electrolyte secondary battery has a positive electrode containing a positive electrode active material, a negative electrode, and a non-aqueous electrolyte solution in which an electrolyte is dissolved in a non-aqueous solvent. The positive electrode active material includes a lithium-containing transition metal oxide that releases oxygen during initial charge, and the non-aqueous solvent contains a fluorinated cyclic carbonate in which fluorine atoms are directly bonded to a carbonate ring.
