Abstract [en]

A 3D-microbattery consisting of nanostructured Cu 2Sb, a solid state electrolyte and a metallic lithium foil has been investigated electrochemically. Thin-film Cu 2Sb electrodes have been prepared by heat treatment of electrodeposited Sb on both 2D and 3D-nanopillar Cu substrates. A solid electrolyte based on UV cross-linked blends of poly(propylene glycol) diacrylate and polyetheramine (glyceryl poly(oxypropylene)) was thereafter deposited onto the electrode material, and then cycled against Li. It is demonstrated that the discharge capacity per footprint area for the 3D-nanopillar samples increased more than 10 times as compared to that of the 2D system.
