Zusammenfassung:	A method for manufacturing a heat spreader including the steps of i. depositing an adhesive on a major surface of at least one graphite layer, to obtain at least one graphite layer coated by an adhesive layer, wherein ii. positioning the at least one graphite layer coated by an adhesive layer on top of each other so as to form a first stack of layers alternating graphite layer and adhesive layer iii. positioning a graphite layer having a thickness from 10 to 200 μm, on the first stack of layers so as to form a second stack of layers, having a graphite layer as top and bottom layers iv. compressing the second stack of layer with a pressure from 7 to 20 MPa to form a graphite-based laminate, v. heating the graphite-based laminate such that the solvent of the adhesive is removed.
