Title:
SODIUM ION CAPACITOR
Document Type and Number:
Japanese Patent JP2013038170
Kind Code:
A
Abstract:

To ensure high energy density, excellent high output characteristics and long life of a low price sodium ion capacitor.

In a capacitor at least having a positive electrode, a negative electrode and an electrolyte, the positive electrode is obtained by filling the porous part of a collector for the positive electrode, consisting of an electrolyte resistant metal porous body having a three-dimensional structure, with a material that can adsorb or occlude/desorb sodium. The electrolyte is a nonaqueous electrolyte containing a sodium salt.
