Abstract:
    This invention discloses a positive and negative plate grid matrial of Ti-base foam lead of lead-acid storage cells, which takes tubular crystals made of Ti or Ti alloy and foam Ti with three-D net structure as the pedestal to plate PbO2 or pure Pb on the pedestal. The preparation method includes: 1, taking TiCl4 and Mg as the raw material, and Mg reduces Ti in TiCl4 in a reduction furnace to be vacuum distilled and condensed to form foam Ti, 2, cutting the Ti foam to mold, 3, eliminating passivation films on the shaped foam Ti to activate it, 4, plating a high conductive layer on the surface of the foam Ti, 5, heat-processing the pedestal, 6, plating PbO2 on the pedestal to get a positive plate grid material or plating pure Pb to get a negative plate grid material.
