POSITIVE ELECTRODE FOR SECONDARY BATTERY, SECONDARY BATTERY, AND METHOD FOR MANUFACTURING SAME

摘要

The present invention provides a positive electrode for a secondary battery and a secondary battery using the positive electrode such that it is possible to inhibit a phenomenon in which the secondary battery cycle continues to degrade if a portion of a solid electrolyte interface is partially damaged after the solid electrolyte interface is formed. This positive electrode for a secondary battery includes chemically adsorbed water in the positive electrode in advance, and the concentration of the chemically adsorbed water included within the positive electrode in advance is in a range of 0.03 - 0.15% by mass of the positive electrode.
