The invention relates to a method (1) for producing a high-carbon material (2), characterised in that it comprises the combination (100) of a structured precursor (10) comprising a fibre or a group of fibres and a non-structured precursor (15), in the form of a fluid, said fluid having a viscosity of less than 45 000 MPa.s -1 at the temperature at which the combination step is carried out, and comprising at least one organic compound which is cyclical or aromatic in the melted state or in solution with a mass concentration lower than or equal to 65%, in such a way as to obtain a combined precursor (20) corresponding to the structured precursor (10) covered with the non-structured precursor (15), said method also comprising the following steps: a step of thermal and dimensional stabilisation (200) of the combined precursor (20) in such a way as to produce a fibre or a group of fibres covered with a cyclical or aromatic organic compound deposit (30), and a step of carbonisation (300) of the fibre or the group of fibres covered with a cyclical or aromatic organic compound deposit (30) in such a way as to produce a high-carbon material (2). |
