Abstract
A present invention provide a lithium ion storage device capable of reliably doping a negative active material of a negative plate with lithium ions generated through dissolution of a lithium metal plate disposed in an electrode group. A conductive shielding member includes a current collecting metal foil and a negative active material layer formed on at least one surface of the current collecting metal foil. The conductive shielding member is provided between a lithium metal plate and a positive plate such that the lithium metal plate is sandwiched between the negative plate and the negative active material layer formed on the current collecting metal foil of the conductive shielding member.
