A non-aqueous electrochemical cell has an anode (2) consisting of an element selected from the group consisting of lithium, sodium and aluminum; a cathode (3) consisting of a porous carbon body (7) and a current collector (6); and an electrolyte containing an oxyhalide, wherein the porous carbon body (7) contains a carbon black having a chain-like structure wherein a thin layer of graphite crystals is formed on a surface of each of carbon black particles. The cell has a high discharge capacity and an excellent discharge efficiency in high rate discharge.
