Electrochemically produced three-dimensional structures for battery electrodes

A continuous process for manufacturing electrical current collectors for primary and secondary batteries by electrochemical deposition, comprising i) providing a first roll and a second roll for winding a continuous electrically conductive substrate co-acting as a working electrode, wherein depending on polarity the working electrode can act as an anode or a cathode, wherein the substrate has first and second parallel sides, a first side whereat deposition or partial dissolution occur, and a second side acting as a counter electrode to close a circuit.
