CURRENT COLLECTOR FOR NON-AQUEOUS ELECTROCHEMICAL CELL AND ELECTRODE EMPLOYING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a current collector for a positive electrode of a nonaqueous electrochemical cell having a superior cycle life, particularly, of an electric double-layer capacitor and a lithium-ion capacitor. SOLUTION: The current collector for a positive electrode of a non-aqueous electrochemical cell is configured as follows. The current collector includes an aluminum complex including an aluminum plate and an aluminum porous sintered compact. The aluminum porous sintered compact has a three-dimensional network structure comprising metal frameworks. The aluminum porous sintered compact includes voids between the metal frameworks. An Al3Ti-based compound is dispersed in the metal frameworks. COPYRIGHT: (C)2011,JPO&INPIT
