Graphite, also called plumbago or black lead, mineral consisting of carbon.Graphite has a layered structure that consists of rings of six carbon atoms arranged in widely spaced horizontal sheets. Graphite thus crystallizes in the hexagonal system, in contrast to the same element crystallizing in the octahedral or tetrahedral system as diamond.Such dimorphous pairs usually are rather similar in ...

Silicon-based anodes are extensively studied as an alternative to graphite for lithium ion batteries. However, silicon particles suffer larges changes in their volume (about 280%) during cycling, which lead to particles cracking and breakage of the solid electrolyte interphase. This process induces .

1/1/2002 · The ball milling of graphite in the presence of a liquid leads to very thin, well-crystallized and anisometric particles. In the presence of water, the graphite particles are covered by γ Fe 2 O 3 (maghemite) formed by the oxidation of the ferrous alloy coming from the milling tools. This composite presents interesting electrochemical properties.
