| titleOfInvention | A kind of copper foil for lithium battery and preparation method thereof |
| abstract | The invention discloses a copper foil for lithium batteries and a preparation method thereof. The copper foil for lithium batteries is based on copper, and a 1-50 nm Me metal layer (Me metal layer) is plated on the surface of the copper foil by plasma sputtering. is: one or more of tin, gallium, silver, gold, bismuth, etc.), and then the surface layer Me is diffused into the copper base through high temperature and high pressure grain boundary diffusion to form a thickness of 1~5μm to form copper with a concentration gradient. Me alloy, and then annealing to relieve stress on the alloy layer to obtain a lithium battery copper foil with good processability. The alloyed copper foil of the invention significantly improves mechanical processing properties such as bending resistance of the copper foil without affecting the conductivity and corrosion resistance of the copper foil, and can be widely used in the fields of lithium ion battery negative electrode current collectors and the like. |
