Abstract: Using pressure-pulsed chemical vapor deposition (PCVD) technique,pyrolytic carbon (pyrocarbon) was coated at 800℃ from C3H8(30%)-N2 gas system on the carbon paper substrate carbonized at 800℃. It was revealed from XRD that the crystallinity of pyrocarbon was higher than that of carbon paper. BET surface area was decreased from 361 m2 g-1 of the original substrate to 2.3 m2 g-1 of the pyrocarbon-coated sample. High irreversible capacity of 550 mA h g-1 was observed in the original carbonized paper,reflecting the disordered structure and high surface area. Irreversible capacity was reduced to 150 mA h g-1 by coating with 8 mass% pyrocarbon, which would be attributed to high crystallinity and low surface area of pyrocarbon. Reversible capacity of the sample coated with 8 mass% pyrocarbon was 597 mA h g-1,which was higher than that of the original carbon paper.
