`
`AMENDMENTS TO THE CLAIMS
`
`This listing of claims replaces all prior versions of claims in the application.
`
`Listing of Claims:
`
`1. (Currently Amended) A non-aqueouselectrolyte secondary battery, comprising:
`
`a positive electrode;
`
`a negative electrode; and
`
`a non-aqueouselectrolyte, wherein
`
`the positive electrode includes a positive electrode active material including complex oxide
`
`particles, including Ni, Co and Li and includingat least either of Mn and Al, wherein a ratio of Ni
`
`to a total number of moles of metallic elements except Li is 50 mol% or more, and
`
`the complex oxide particles have a ratio (A/B) of a BETspecific surface area (A) (m7/g) to
`
`a theoretical specific surface area calculated by the following expression (B) (m7/g) (443) of more
`
`than 1.0 and less than 2.5:
`
`Theoretical specific surface area (B) (m7/g) = 6/(true density (g/cm*) x volume average
`
`particle size (um)).
`
`2. (Original) The non-aqueouselectrolyte secondary battery according to claim 1, wherein
`
`the volumeaverageparticle size of the complex oxide particles is 2 um or more and 6 um
`
`or less.
`
`3. (Currently Amended) The non-aqueous electrolyte secondary battery according to claim 1,
`
`wherein
`
`the ratio (A/B) of the BET specific surface area (A) to the theoretical specific surface area
`
`
`
`Application No.: 16/635,018
`
`Docket No.: P200091US00
`
`(B) (4/3) is more than 1.0 and less than 2.5.
`
`4. (Previously Presented) The non-aqueous electrolyte secondary battery according to claim 1,
`
`wherein
`
`the BET specific surface area (A) is 0.2 m?/g or more and 5 m’/g orless.
`
`5. (New) The non-aqueouselectrolyte secondary battery according to claim 1, wherein
`
`the true density of the complex oxide particles is 4.3 g/cm? or more and 4.7 g/cm’orless.
