【Abstract】 This paper puts forward a new method that adds dissolvable stuff in metal powder by mixing, cold working, eliminating stuff to acquire a porous electrode sheet. The preliminary research shows the method can not only overcome the conflict of being not able to meet the high mechanical intensity and high porosity by cold working-sintering method, but also solve the difficulty of making porous electrode sheet of smaller pore diameter and thinner thickness by penetration casting technique. It’s possible to get high porosity and high intensity thin porous electrode sheet by controlling the proportion of metal material and stuff, so as to realize the once preparation process of low cost directly from powder formation.更多还原
