Document Type and Number:
WIPO Patent Application WO/2021/049218
Kind Code:
A1
Abstract:
Provided is a graphite sheet capable of being combined with a base material even without requiring the use of an adhesive. The surface layer porous graphite sheet (100) according to an embodiment of the present invention comprises a porous layer (20) positioned on one or both surface layers of the surface layer porous graphite sheet (100) and a graphite layer (10) adjacent to the porous layer (20). The pores (22) of the porous layer (20) include pores (22a') for which the pore diameter Y in the interior of the porous layer 20 is larger than the pore diameter X on the surface of the porous layer (20). The porosity in a cross section of the surface layer porous graphite sheet (100) taken vertically satisfies a predetermined condition.
