Patent ID: 8248757

Claim:
A nonaqueous lithium-type storage element comprising: a negative electrode active material that stores and emits a lithium ion; and a positive electrode active material of activated carbon having a BET specific surface area of 1,500 m 2 /g or more and 3,000 m 2 /g or less, when a mesopore volume relating to a pore with a diameter of 20 angstrom or more and 500 angstrom or less and calculated by a BJH method is defined as V1 (cc/g) and a micropore volume relating to a pore with a diameter of less than 20 angstrom and calculated by an MP method is defined as V2 (cc/g), V1 and V2 satisfy the following ranges: 0.3 <V 1≦0.8, 0.5 ≦V 2≦1.0, and 0.3 ≦V 1/V2≦0.9.
