Title:
SECONDARY BATTERY AND METHOD OF PREPARING THE SAME
Document Type and Number:
WIPO Patent Application WO/2021/225304
Kind Code:
A1
Abstract:
A secondary battery includes a cathode layer including a cathode active material layer; an anode layer including an anode current collector and a metal layer disposed on the anode current collector; a solid electrolyte layer disposed between the cathode layer and the anode layer; and a graphite interlayer disposed between the solid electrolyte layer and the anode layer, wherein the interlayer comprises a graphite material having a crystallite size of about 1000 angstroms to about 1500 angstroms, when measured from a (110) diffraction peak, and having a hexagonal interplanar spacing about 500 angstroms to about 800 angstroms in a c-axis direction, when measured from a (002) diffraction peak, an aspect ratio of the graphite material is in a range of between about 0.44 and about 0.55.
