ELECTRODE, SECONDARY BATTERY, BATTERY PACK, VEHICLE and STATIONARY POWER SOURCE
Document Type and Number:
WIPO Patent Application WO/2020/054107
Kind Code:
A1
Abstract:
An electrode comprises a current collector; and an active material-containing layer has active materials on the current collector; wherein the active material-containing layer has a first surface contacting the current collector and a second surface which is opposite side of the first surface, at least one part of the second surface is covered by a compound containing Zn, when an image of the second surface is taken by Scanning Electron Microscope, the image is divided 100 blocks a ratio of existence of blocks having the compound containing Zn shaping hexagonal plate to the 100 blocks is calculated and the ratio of existence of blocks is calculated about 10 images, an average of the ratio of existence of blocks about the 10 images is 20% or less (containing 0).
