Abstract: The disclosure relates to a carbon-based electrode material that has been graphitized to hold ions in the electrode of a battery and more particularly include carbide or carbide and nitride surfaces that protect the graphite core. The preferred batteries include metal ion such as lithium ion batteries where the carbon-based electrode is the anode although the carbon-based electrode may also serve in dual ion batteries where both electrodes may comprise the graphitized carbon-based electrodes. The electrodes are more amorphous than conventional graphite electrodes and include a carbide or nitride containing surface treatment.

Abstract: A process for binding sulfur to carbon to form carbon polysulfide is described that better secures sulfur to the cathode in a lithium-sulfur battery during lithium oxidation and reduction. The process includes selecting a suitable carbon precursor, blending it with sulfur and an organic solvent and mill the combination to make a fine particle size mix and then driving off the solvent along with species that have been dissolved in the solvent. The remaining carbon precursor and sulfur are heated in an inert environment at a temperature between about 300° C. and about 550° C. to chemically bind the sulfur and the carbon to form carbon polysulfide suitable for use as a cathode powder in a lithium-sulfur battery.

Abstract: The invention relates to removing contaminants from oil using solid sorbents that are comprised primarily of carbon and preferably of coke particles. The coke particles have an affinity for contaminants in oil and are sized to be filtered from oil without plugging. Most contaminants have such a small size that they tend to plug up filters. As the contaminants agglomerate onto the solid sorbent, the resulting particles form a filter cake on conventional filter materials in such a way as to allow the oil to pass on through without significant pressure drop or delay.
Abstract translation: 本发明涉及使用主要由碳和优选焦炭颗粒组成的固体吸附剂从油中除去污染物。 焦炭颗粒对油中的污染物具有亲和力，并且其尺寸可以从油中过滤而不堵塞。 大多数污染物具有如此小的尺寸，使得它们倾向于堵塞过滤器。 当污染物聚集到固体吸附剂上时，所得到的颗粒在常规过滤材料上形成滤饼，以使油通过而没有显着的压降或延迟。
