Zusammenfassung: | A non-aqueous electrolyte secondary battery includes a positive electrode, a negative electrode, and a non-aqueous electrolyte, in which lithium metal deposits on the negative electrode during charge, and the lithium metal dissolves from the negative electrode into the non-aqueous electrolyte during discharge. The positive electrode includes a positive electrode active material, the positive electrode active material includes a composite oxide containing lithium and a transition metal, and the non-aqueous electrolyte contains an oxalate salt. The composite oxide contains Ni and at least one selected from the group consisting of Fe, V, Ti, and Nb, and has a structure based on a crystal structure belonging to a space group R-3m. |
