Abstract
This positive electrode precursor includes: a positive electrode active material containing a carbon material and an alkali metal compound, wherein 5≤A≤35, when A (g/m) is a weight of the alkali metal compound in the positive electrode active material layer at one surface of the positive electrode precursor, 10≤B≤100 as well as 0.20≤A/B≤1.00, when B (g/m) is a weight of the positive electrode active material in the positive electrode active material layer, and 1≤C≤20, when C (m/cm) is a specific surface area per unit area as measured by the BET method at one surface of the positive electrode precursor.
