Positive Electrode Precursor

A nonaqueous hybrid capacitor comprising an electrode laminated body,

• wherein the electrode laminated body comprises:
• a positive electrode precursor;
• a negative electrode;
• and
• a separator,
• wherein the positive electrode precursor comprises:
• a positive electrode active material containing a carbon material;
• and
• an alkali metal compound,
• wherein the positive electrode precursor has one surface and another surface, and a positive electrode active material layer is present at the one surface or both the one surface and the other of the positive electrode precursor,
• wherein 5≤A≤35, when A (g/m2) is a weight of the alkali metal compound in the positive electrode active material layer at the one surface of the positive electrode precursor,
• wherein 10≤B≤100 as well as 0.20≤A/B≤1.00, when B (g/m2) is a weight of the positive electrode active material in the positive electrode active material layer,
• wherein 1≤C≤20, when C (m2/cm2) is a specific surface area measured by the BET method using nitrogen as an adsorbate at the one surface of the positive electrode precursor per unit area of the one surface of the positive electrode precursor,
• wherein A/G1 is equal to or larger than 1.0 (g/Ah) and equal to or smaller than 2.0 (g/Ah), when G1 (Ah/m2) is a Capacitance Per Unit Area of the One Surface of the Negative electrode.
