Lithium-ion secondary battery
In a lithium-ion secondary battery (100), positive active material particles (610) have a shell (612) formed by a lamellar lithium transition metal oxide, a hollow portion (614) formed in the shell (612), and a through hole (616) that runs through the shell (612). A positive active material layer (2...
