    • A method for fabricating carbon electrode coated with a porous metal film includes the steps of: positioning a roll of carbon material within a vacuum chamber; winding the carbon material off the roll at a certain speed, winding the carbon material on a different roll while coating a porous metal to a thickness of a few Řa few &mgr;m on the carbon material between the two rolls from a metal evaporation source; and stabilizing the thusly coated carbon material under a vacuum. The coated porous metal film is of Li, Al, Sn, Bi, Si, Sb, Ni, Cu, Ti, V, Cr, Mn, Fe, Co, Zn, Mo, W, Ag, Au, Pt, Ru, Ir, In or their alloys. Since the stable film is formed on the surface of the carbon material, when the thusly coated carbon material is use for forming a cathode electrode of a secondary battery, the reversibility and high rate charging and discharging characteristics of the carbon electrode can be improved. In addition, when a lithium-ion secondary battery is fabricated using the carbon electrode coated with lithium or a lithium alloy, the capacity degradation due to the irreversible capacity of the conventional carbon electrode appearing at the initial state of charging can be prevented, so that the capacity can be increased.
    • 涂覆有多孔金属膜的碳电极的制造方法包括以下步骤:将碳材料卷定位在真空室内; 以一定的速度将碳材料从轧辊上卷绕,将碳材料卷绕在不同的辊上,同时在来自金属蒸发源的两个辊之间的碳材料上涂覆几微米厚度的多孔金属; 并在真空下稳定如此涂覆的碳材料。 涂层多孔金属膜为Li,Al,Sn,Bi,Si,Sb,Ni,Cu,Ti,V,Cr,Mn,Fe,Co,Zn,Mo,W,Ag,Au,Pt,Ru,Ir ,In或它们的合金。 由于在碳材料的表面上形成稳定的膜,所以当这样涂覆的碳材料用于形成二次电池的阴极时,可以提高碳电极的可逆性和高速充放电特性。 此外,当使用涂覆有锂或锂合金的碳电极制造锂离子二次电池时,可以防止由于在初始充电状态下出现的常规碳电极的不可逆容量导致的容量降低,使得 可以增加容量。
