摘　　要：报道了可以代替泡沫镍作MH－Ni电池阳极骨架材料用镍纤维毡的制备工艺，研究了镍纤维丝径、镍毡的单重对孔径尺寸、孔隙率、比表面积的影响。经过在氢气和氩气2种气氛中进行烧结，保证了镍毡的抗拉强度和延伸变形率，可以制备出性能优良的镍纤维毡。A Ni metal fiber felt is recommended for use as an anode substrate in the metal hydride-nickel(MH-Ni) battery insteadof foamed nickel in the development of a high capacity, high current battery. The processing of the Ni fiber felt is described. Theinfluence of fiber diameter and area density on the pore size, porosity and specific surface area of the Ni fiber felt are described.After sintering under an atmosphere of hydrogen or argon, the tensile strength and elongati0n of the felt can be improved. Thefelts with different physical properties have been obtained.
