0000 A method for forming hard carbon from an asphaltene precursor derived from bitumen. The asphaltene precursor is oxidized in an oxygen-rich atmosphere at one or more temperatures to produce an oxidized asphaltene. The oxidized asphaltene is then carbonised at an elevated temperature under an inert atmosphere to produce hard carbon having an interlayer spacing suitable for sodium-ion intercalation. The asphaltene precursor may be treated with an oxidizing agent prior to oxidizing at an elevated temperature. The method may further comprise milling the asphaltene precursor or the oxidized asphaltene to a powder after acid treatment, after oxidization at elevated temperature or after carbonization. The resulting hard carbon is suitable for use as an anode material in sodium-ion batteries.
