| 简介 |
Provided is a positive electrode for a nonaqueous-electrolyte secondary battery whereby even if said positive electrode is set to a high electric potential, degradation of cycle characteristics is minimized. Said positive electrode for a nonaqueous-electrolyte secondary battery has a positive-electrode plate comprising a positive-electrode mixture layer formed on top of a positive-electrode collector. Said positive-electrode mixture layer contains a binder, a conductive agent, and a positive-electrode active material onto/from which lithium is adsorbed and desorbed. A compound containing at least one element selected from among tungsten, aluminum, magnesium, titanium, zirconium, and the rare-earth elements is attached to the surface of at least part of the positive-electrode active material in the positive-electrode mixture layer, the surface of at least part of the binder, and the surface of at least part of the conductive agent. |
