    Abstract: Embodiments of the present disclosure generally relate to carbon materials for battery electrodes and methods for preparing such carbon materials. More specifically, embodiments relate to coated nano-ordered carbon particles and methods for coating a carbon film onto carbonaceous particles to produce the coated nano-ordered carbon particles which can be used as an anode material within a rechargeable battery, such as a sodium-ion battery, other types of batteries. In one or more embodiments, a method for producing coated nano-ordered carbon particles is provided and includes exposing a carbon-containing material to an expanding agent to produce expanded carbonaceous particles during an expanding process, heating the expanded carbonaceous particles during an annealing process, and depositing a carbon film on the nano-ordered carbon particles to produce coated nano-ordered carbon particles during a carbon coating process.

    Abstract: Embodiments of the present disclosure generally relate to methods for preparing carbon materials which can be used in battery electrodes. More specifically, embodiments relate to methods for preparing nano-ordered carbon products used as anode materials in metal-ion batteries, such as a lithium-ion battery. In one or more embodiments, a method includes exposing a liquid refinery hydrocarbon product to a first functionalization agent to produce a first solid functionalized product during a first functionalization process and exposing the first solid functionalized product to a second functionalization agent to produce a second solid functionalized product during a second functionalization process. Each of the first and second functionalization agents independently contains an element selected from oxygen, sulfur, phosphorous, nitrogen, or any combination thereof. The method also includes carbonizing the second solid functionalized product at a temperature of about 1,000° C. to about 1,400° C. to produce a solid nano-ordered carbon product during a carbonization process.

    Abstract: Embodiments of the present disclosure generally relate to methods for preparing carbon materials which can be used in battery electrodes. More specifically, embodiments relate to methods for preparing nano-ordered carbon products used as anode materials in metal-ion batteries, such as a sodium-ion battery. In some embodiments, a method includes fractioning an initial refinery hydrocarbon product during a fractionation process to produce a liquid refinery hydrocarbon product and a heavy refinery hydrocarbon product. The method includes exposing either or both refinery hydrocarbon products to a first functionalization agent to produce a first solid functionalized product during a first functionalization process and purifying the first solid functionalized product during a purification process. The method also includes exposing the first solid functionalized product to a second functionalization agent to produce a second solid functionalized product during a second functionalization process and carbonizing the second solid functionalized product to produce the nano-ordered carbon product during a carbonization process.
