Title:
POWER STORAGE DEVICE ELECTRODE AND LITHIUM ION SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2022/208625
Kind Code:
A1
Abstract:
A power storage device electrode including a resin layer 11, a conductive layer 12 that is disposed on the resin layer 11 and contains copper, and an active material layer 20 that is disposed on the conductive layer 12 and contains graphite. If an X-ray diffraction method is used to perform a measurement from the surface of the active material layer 20, the peak intensity ratio A/B of the intensity A of the highest X-ray diffraction peak in the range of the diffraction angles 48°-53° to the intensity B of the highest X-ray diffraction peak in the range of the diffraction angles 52°-57° satisfies equation (1): 0.3 ≤ A/B ≤ 1.
