| 摘要 |
A lithium ion secondary battery capable of improving the lithium ion input-output characteristics. An active material capable of storing and releasing lithium ions is a Li complex oxide or a Li complex oxoacid salt. A plurality of primary particles have a particle size distribution with 1 nm<D10<65 nm, 5 nm<D50<75 nm, and 50 nm<D90<100 nm. The maximum peak pore size A in a pore size distribution as measured by a mercury intrusion technique is 10 nm≰A≰75 nm. The ratio B/A of the maximum peak pore size A and the crystallite size B is 0.5≰B/A≰1.
