Using pressure-pulsed chemical vapor infiltration (PCVI) method, TiN was partially infiltrated at 850 degrees C from gas system of TiCl(4) (1%)-N(2) (10%)-H(2) into the highly porous carbon substrates prepared by the carbonization of cotton-wool, filter paper, and wood at 1,000 degrees C in Ar for 4 h. After 10,000 pulses of PCVI, electro-conductive porous ceramics having the three-dimensionally continuous current paths were obtained, which had the porosity of 80% and more, the resistivity of 10(-5)-10(-6) Omega m, and the average pore sizes of 10-40 mu m. The geometric surface area per unit volume of the sample was higher than that of the conventional foil-type current collector for lithium-ion battery. The surface area showed the highest value for the sample obtained from carbonized wood substrate.
