1. Fremgangsmåde til fremstilling afen batterielektrode, omfattende: dannelse (S100) afen belægningsfilm (70) på et kollektorsubstrat (60) ved at belægge et stort område af kollektorsubstratet (60) med en blækagtig belægningsfilm; tørring eller hærdning af den påførte belægningsfilm; kalandrering af det belagte kollektorsubstrat (60); fremstilling (S200) af mindst ét aflederområde (40) ved fjernelse af belægningsfilmen (70) med laserablation, kendetegnet ved, at der ved fremstilling af aflederområdet (40) fjernes et lag af kollektorsubstratet (60) i aflederområdet (40) vha. laserablation ved styring af laserens indtrængningsdybde i kollektorsubstratet (60).
2. Fremgangsmåde ifølge krav 1, hvor belægningsfilmen (70) påføres begge sider af kollektorsubstratet (60) og/eller en samlet overflade af kollektorsubstratet (60) og/eller i en kontinuerlig belægningsproces.
3. Fremgangsmåde ifølge krav 1 eller 2, hvor der på mindst én side af kollektorsubstratet (60) dannes mindst ét aflederområde (40) ved laserablation.
4. Fremgangsmåde ifølge et af ovenstående krav, hvor der sker en kollektorsubstratskontaktering (S500) i aflederområdet (40) med en tilslutningsfane (50) umiddelbart efter dannelsen af aflederområdet (40).
