Claims18
A manufacturing method for negative tab of pouch cell, comprising the following steps of:
- cleaning and surface roughening a copper foil substrate:
- a gaseous fluid decomposed into high reactivity particles including ion, electronic and free radical by using plasma, these high reactivity particles cleaning and roughening a surface of a copper foil substrate and promoting a surface roughness of the copper foil substrate under a room temperature about 15° C. to 30° C.;
- plating a nickel film:
- a nickel film plated onto the roughened surface of the copper foil substrate by vacuum sputter, wherein the surface roughened copper foil substrate is provided to promote an adhesive quality between the copper foil substrate and the nickel film;
- cleaning and surface roughening the nickel film:
- a gaseous fluid decomposed into high reactivity particles including ion, electronic and free radical by using plasma, these high reactivity particles cleaning and roughening a surface of the nickel film and promoting a surface roughness of the nickel film under a room temperature about 15° C. to 30° C.;
- plating a passivated metal film:
- a passivated metal film plated onto the nickel film by vacuum sputter, wherein the passivated metal film is provided to protect the negative tab from being corroded by electrolyte and the surface roughened nickel film is provided to promote an adhesive quality between the passivated metal film and the nickel film;
- and
- cleaning and surface roughening the passivated metal film:
- a gaseous fluid decomposed into high reactivity particles including ion, electronic and free radical by using plasma, these high reactivity particles cleaning and roughening a surface of the passivated metal film and promoting a surface roughness of the passivated metal film under a room temperature about 15° C. to 30° C.
A manufacturing method for positive tab of pouch cell, comprising the following steps of:
- cleaning and surface roughening an aluminum foil substrate:
- a gaseous fluid decomposed into high reactivity particles including ion, electronic and free radical by using plasma, these high reactivity particles cleaning and roughening a surface of an aluminum foil substrate and promoting a surface roughness of the aluminum foil substrate under a room temperature about 15° C. to 30° C.;
- plating a passivated metal film:
- a passivated metal film plated onto a roughened surface of the aluminum foil substrate by vacuum sputter, wherein the passivated metal film is provided to protect the positive tab from being corroded by electrolyte and the surface roughened of the aluminum foil substrate is provided to promote an adhesive quality between the passivated metal film and the aluminum foil substrate;
- and
- cleaning and surface roughening the passivated metal film:
- a gaseous fluid decomposed into high reactivity particles including ion, electronic and free radical by using plasma, these high reactivity particles cleaning and roughening a surface of the passivated metal film and promoting a surface roughness of the passivated metal film under a room temperature about 15° C. to 30° C.
