The plate-type negative electrodes for Li-ion rechargeable battery were prepared by pressure-pulsed chemical vapor infiltration of pyrolytic carbon at 950degreesC from C3H8 (30%)-H-2 into the TiN-based electroconductive forms having the fibrous structure. The electrodes had the three-dimensional current paths in the layers of active materials without the organic binders and the conductive additives. The charge-discharge profiles were similar to that observed in non-graphitizable carbon having disordered structure. Reversible capacity of pyrolytic carbon at current density of 0.2 mA cm(-2) and coulombic efficiency at the first cycle weresimilar to500 mA h g(-1) andsimilar to72%, respectively. The capacity at current density of 8 mA cm(-2) maintained 80% of that at 0.2 mA cm(-2) .
