Title:
POSITIVE ELECTRODE FOR POWER STORAGE DEVICE AND POWER STORAGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/208733
Kind Code:
A1
Abstract:
This positive electrode 1 for a power storage device is provided with an active substance layer 10, a current collector 20 and a conductive layer 30. The active substance layer 10 contains an electrochemically active polymer 12 and a conductive assistant 14. The conductive layer 30 is disposed between the active substance layer 10 and the current collector 20, and is in contact with the active substance layer 10 and the current collector 20. The thickness of the conductive layer 30 is measured at 10 points spaced at intervals of 2 µm along the boundary between the current collector 20 and the conductive layer 30 in a cross section of the positive electrode 1 for a power storage device taken perpendicularly to the main surface of the current collector 20 in contact with the conductive layer 30. The average thickness of the conductive layer 30 determined through the measurement is 0.5 to 3.0 µm.
