Abstract
A positive electrode active material for a lithium secondary battery includes secondary particles which are aggregates of primary particles that are capable of being doped and dedoped with lithium ions, in which the secondary particles have a total specific surface area of pores having a pore radius of 10 nm or more and 50 nm or less of 0.27 m2/g or more and 0.90 m2/g or less in a pore distribution measured by a mercury porosimetry method.
