Patent ID: 8318343

Claim:
A positive electrode including a positive-electrode active material and being used for a nonaqueous electrolyte cell, the positive electrode comprising: a coating, wherein: the coating contains at least one first compound for which a binding-energy peak in a phosphorus 2p spectrum obtained by X-ray photoelectron spectroscopy is in the range of 132 to 135 eV, the first compound being selected from the group consisting of: Li 2 HPO 3 , Li 3 PO 3 , LiH 2 PO 3 , LiH 2 PO 2 , Li 2 HPO 2 and Li 3 PO 2 , the positive electrode includes a positive-electrode active material layer containing the positive-electrode material, and the coating is disposed on a surface of the positive-electrode active material layer or on surfaces of particles of the positive-electrode active material.
