 · There has been relatively low urgency surrounding graphite supply risks for electric vehicles, given EVs have historically only demanded a small fraction of total natural graphite supply. Furthermore, the increase in graphite demand for EVs in recent years has coincided with a lowering demand in the steel industry (the major user of medium flake natural graphite), which has kept prices low [44] .

Graphite

Mexico and Canada export graphite mainly to the United States, which has not had domestic production of natural graphite since the 1950s. Most graphite deposits in the United States are too small, low-grade, or remote to be of commercial value in the near future, and the likelihood of discovering larger, higher-grade, or favorably located domestic deposits is unlikely.
