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