Abstract

An apparatus and method are provided for manufacturing particles. The apparatus and method may be implemented in a roll-to-roll fashion for continuous or intermittent production of particles, using membranes passing from station to station propelled by rollers.

First claim

1 . An apparatus for manufacturing particles, the apparatus comprising:
one or more membrane layers that are conductive and one or more membrane layers that are non-conductive, a tool to create holes or other structures in at least one of the non-conductive membrane layers so that one or more portions of one or more of the conductive membrane layers is exposed to an electrolyte or other solution through at least one portion of the created holes or other structures.

2 . The apparatus of claim 1 , where the one or more conductive and non-conductive membrane layers is a reel stock.

3 . The apparatus of claim 1 , where the shaping tool is a laser or other light source.

4 . The apparatus of claim 1 , wherein the one or more conductive and non-conductive membrane layers is a flexible reel stock, and further comprising at least one station in which material is deposited in a multiplicity of the holes in the roll of flexible reel stock, wherein a region of the reel stock is exposed to an electrolyte solution bath containing metallic ions.

5 . The apparatus of claim 1 , where the one or more of non-conductive layers have been created by selective stabilization of a material deposited on one or more of the conductive layers.

6 . A method for manufacturing particles, wherein a tool is used to create said holes and other structures in at least one non-conductive membrane so that a portion of at least one other conductive membrane, is exposed through at least one portion of the created holes in the at least one non-conductive membrane, and wherein a region of the at least one non-conductive membrane is exposed to an electrolyte solution, so as to deposit material in a multiplicity of through-holes in the at least one non-conductive membrane.

7 . The method of claim 6 , where the tool is a laser.

8 . The method of claim 6 , wherein the at least one non-conductive membrane is a flexible reel stock.

9 . The method of claim 6 , where at least one section of the at least one non-conductive membrane has been created by selective stabilization of a non-conductive material deposited on one or more of the conductive layers through exposure to light, and holes in the non-conductive layer are created by removal of regions that have not been stabilized.
