Abstract
Graphite stands as a critical element, as recognized by the US Department of Energy, owing to its pivotal role as anodes in batteries. The demand for high-purity graphite in battery applications is poised to surge in the foreseeable future. Synthetic graphite, prized for its high purity, typically emerges as the preferred option for such applications. However, the current synthesis process for graphite is exceedingly energy-intensive, mandating heat treatment of carbon precursors at temperatures soaring up to 3300 K for successful graphitization. In this talk, a novel method for graphitization is presented, one that operates at significantly lower temperatures and harnesses an electrochemical approach. Through cathodic electrochemical polarization of amorphous carbon in molten salts, the transformation of amorphous carbon into a highly graphitic structure is achieved. This innovative process holds promise in conserving substantial energy compared to existing methodologies.
