    ARTIFICIAL GRAPHITE FOR NEGATIVE ELECTRODE OF LITHIUM ION ...

    A method for production of artificial graphite for the negative electrode of a lithium ion secondary battery, comprising: a first step of coking treatment of a stock oil composition obtained by combining two or more different stock oils selected from among vacuum residue oil, FCC heavy oil and desulfurized heavy oil produced in the petroleum refining process, a second step of calcining the treated product obtained from the first step at a temperature of 1200-1500° C., and a third step of ...

    Li-based all‑carbon dual-ion batteries using graphite ...

    In the present work, we demonstrate the possibility of recycling graphite recovered from spent Li-ion batteries for Li-ion based all‑carbon dual-ion battery (ACDIB) application. Graphite electrodes recovered from failed commercial batteries were thermally treated at different temperatures to optimize their electrochemical activity.

    The prospects of artificial graphite and natural graphite ...

    Such a product is modified artificial graphite, which has the characteristics of high compaction, long cycle time, and low expansion rate. Using it as the negative electrode of a lithium battery can improve its conversion with electrolyte, reduce the swelling of the pole shoe, and have a positive impact on the overall life of the replacement battery. The production process is to replace artificial graphite with pitch, etc. and carbonize. An amorphous carbon-doped layer is formed on the ...
