Abstract: A battery with a carbonaceous anode and a lithium manganese oxide spinel cathode. The carbonaceous anode is manufactured from graphite particles selected from the group consisting of: synthetic graphite particles, carbon-coated graphite particles, carbonized petroleum coke particles, carbon-coated coke particles and mixtures thereof. The lithium manganese oxide spinel cathode has a valence above 3.5. The production of the carbonaceous anode is obtained by: a) determining the initial coulombic efficiency and the specific capacity of the lithium manganese oxide spinel cathode in a cell against lithium metal; b) selecting a desired mixture of the graphite particles; c) comparing the initial coulombic efficiency of the graphite particles to that of the lithium manganese oxide spinel cathode; and d) selecting the appropriate amount and mixture of the graphite particles so that the initial coulombic efficiency of the carbonaceous anode is lower than that of the lithium manganese oxide spinel cathode.

Abstract: Methods and compositions relate to anode powders for use in batteries. The powders may provide limited surface area per volume of powder material. Further, the powders may include limited amounts of particles below a threshold size within a particle size distribution. Some embodiments utilize regular or anode grade petroleum coke as a precursor.

Abstract: A process for preparing fibers, including: (a) providing a spinning mixture including a dispersion of a flashing agent and an excess of a carbonaceous pitch; and (b) passing the spinning mixture from a high pressure region through an orifice to a low pressure region to form polyfilamentary pitch fibers. The pitch fibers may optionally be further treated to form polyfilamentary carbon fibers or graphite fibers, which may be incorporated into a resin to form a lightweight, conductive composite.

Abstract: Recarburizer coke containing not more than 0.1 weight percent sulfur and not more than 0.1 weight percent nitrogen is prepared by the catalytic hydrogenation, thermal cracking, and delayed coking of a mixture of pyrolysis tar and petroleum distillate.

Abstract: A virgin heavy oil is hydrotreated, separated into a light fraction and a heavy fraction which are separately delay coked to obtain (a) a coke product of low sulfur content suitable for use as recarburizer coke or for use in the manufacture of graphite electrodes used in the manufacture of steel and (b) a coke product of higher sulfur content suitable for use in electrodes employed in the manufacture of aluminum.
