CURRENT COLLECTOR FOIL, ELECTRODE STRUCTURE, LITHIUM SECONDARY CELL, OR ELECTRIC DOUBLE-LAYER CAPACITOR |
摘要 |
The present invention provides a current collector foil; and an electrode structure, lithium secondary battery or an electrical double layer capacitor using the current collector foil, which can achieve superior high rate characteristics. Provided is a current collector foil for forming thereon an active material layer containing active material particles, wherein: the current collector foil is provided with a roughened portion; a cross sectional curve of the roughened portion has a box counting dimension of 1.1 or higher; and an average length of waviness motif AW of the cross-sectional curve of the roughened portion is longer than twice of D10, D10 being a particle diameter of the active material particle in particle size cumulative distribution, the active material particle being used for the active material layer formed on the current collector foil. |
