Abstract
A lithium metal composite oxide and the like capable of improving an initial charge and discharge efficiency are provided. In a curve, pores of the lithium metal composite oxide include first pores in which a pore size dp and a maximum pore size dpm satisfy a relationship represented by dp/dpm < 0.10, second pores in which the pore size dp and the maximum pore size dpm satisfy a relationship represented by 0.10 ≤ dp/dpm ≤ 0.65, and third pores in which the pore size dp and the maximum pore size dpm satisfy a relationship represented by dp/dpm > 0.65. A volume V1 of the first pores, a volume V2 of the second pores, and a volume V3 of the third pores satisfy relationships represented by "0 < 100·V1/(V1 + V2 + V3) ≤ 70" and "0 < 100·V3/(V1 + V2 + V3) ≤ 15".
