Japanese Patent JP7343304

B2

To provide a positive electrode precursor, containing a carbon material and an alkali metal compound, in which corrosion during storage is suppressed, and to provide a non-aqueous power storage element, obtained using the positive electrode precursor, in which micro short circuits are reduced.SOLUTION: A positive electrode precursor has a positive electrode current collector and a positive electrode active material layer disposed on the positive electrode current collector. The positive electrode active material layer includes a positive electrode active material containing a carbon material and includes an alkali metal compound. A mass ratio of the alkali metal compound in the positive electrode active material layer is 10% by mass or more and 50% by mass or less. The positive electrode active material layer has a water content of 100 ppm by mass or more and 2% by mass or less.SELECTED DRAWING: None
