  • Hydrocarbon treatment of carbonaceous materials
    Patent number: 6143268
    Abstract: A method for making a carbonaceous material suitable for use as an electrode composition that includes contacting pyrolyzed organic material with hydrocarbon gas for a period and at a temperature sufficient to produce a carbonaceous material characterized such that when the carbonaceous material is incorporated into an electrode composition of a lithium-ion cell, the cell exhibits a reversible capacity of at least about 400 mAH/g of carbonaceous material and an irreversible capacity no greater than about 140 mAH/g of carbonaceous material, the capacities being measured up to the point of plating of metallic lithium on the surface of the carbonaceous material.
