Recently, surface-modification by coating with pyrolytic carbon (pyrocarbon) using chemical vapor deposition (CVD) has been applied to graphite-based anodes of lithium-ion secondary battery (LIB) to restrain the decomposition of propylene carbonate based solvent. For non-graphitizing carbon coated with thin pyrocarbon film using chemical vapor infiltration (CVI), the irreversible capacity was significantly reduced without the decrease of reversible capacity, reflecting the laminar texture, high crystallinity and low surface area of pyrocarbon. Thus, pyrocarbon-coating by CVD/CVI technique is effective in improving the electrochemical properties of anode carbons. In present paper, recent works were summarized on synthesis and modification of anode carbons for LIB using CVD, especially CVI technique.
