| Abstract Scope |
Graphite is considered by the US Department of Energy to be a critical element. Due to its widespread use as anodes in batteries, the demand for high purity graphite for battery applications is expected to increase for the foreseeable future. Synthetic graphite, due to its high purity is generally the preferred choice for battery applications. The current process for the synthesis of graphite is very energy intensive and requires heat treatment of carbon precursor to temperature up to 3300 K for successful graphitization. In the paper, a new method for the graphitization is reported, once that requires significantly lower temperatures and employs an electrochemical approach. Cathodic electrochemical polarization of amorphous carbon in molten salts at around 1100 K, transforms amorphous carbon to a highly graphitic structure. This process has the potential to save significant energy compared to existing process. |
