A kind of preparation method of the compound porous collector of foil/carbon, it is characterised in that comprise the following steps：S11 decontaminations are dried：Porous foil collector is gone to degrease and dried；S12 ion implantings：First dried porous foil collector is inserted in ion implantation apparatus, is passed through in inert gas after sealing, then using the method for high-speed ion injection, carbon is injected into the one side of the porous foil collector；Wherein, the ion implanting amount of the compound porous collector is 0.5 × 1014~1.5 × 1018ion/cm 2 , injection length is 1~20 minute, and Implantation Energy is 1 10keV；This step is repeated once with identical parameter, the carbon of equivalent is injected in the another side of the porous foil collector, the compound porous collector of foil/carbon is obtained after cleaned drying.Present invention additionally comprises a kind of compound porous collector positive/negative plate of foil/carbon and the preparation method of lithium battery. |
