Title:
蓄電デバイス
Document Type and Number:
Japanese Patent JP4139960
Kind Code:
B2
Abstract:
To provide a high output power storage device which has a small irreversible capacitance.
The power storage device has a positive electrode containing a nitroxyl compound which turns into a N-oxo-ammonium cation partial substructure as shown by formula (I) in the oxidation state and turns into a nitroxyl radical partial substructure as shown by formula (II) in the reduction state, and uses a reaction shown by reaction formula (A) that performs electron transfer between above two states as a positive electrode reaction. A negative electrode contains active carbon covered by pitch.
