1. A process for manufacturing a carbonaceous anode for an electrolysis cell for the production of aluminium comprising:
contacting coke particles with a boron-containing solution to obtain boron-impregnated coke particles;
mixing the boron-impregnated coke particles with coal tar pitch to form an anode paste; and
forming a green anode with the anode paste.
