摘要

PROBLEM TO BE SOLVED: To provide a production method of positive electrode ink for nonaqueous electrolyte secondary battery, i.e. concrete means for manufacturing the positive electrode for nonaqueous electrolyte secondary battery or a nonaqueous electrolyte secondary battery that can produce the original potential of the battery, and to provide the positive electrode ink for a nonaqueous electrolyte secondary battery, and a manufacturing method of the positive electrode for a nonaqueous electrolyte secondary battery.SOLUTION: In the positive electrode for a nonaqueous electrolyte secondary battery, an active material layer composed of an active material consisting of LiMPO(M is Fe or Mn or a mixture thereof), a conductive material and a binder and having a bulk density of 1.2 g/cmor higher is laminated on a collector substrate.
