Abstract
An integrated array of thick Li 4 Ti 5 O 12 electrodes was fabricated by electrophoretic deposition (EPD). A precisely controlled electric field distribution by the three-electrode EPD system enabled the formation of Li 4 Ti 5 O 12 electrodes on the lines selected in the interdigitated microarray Au current collectors. The array of Li 4 Ti 5 O 12 electrodes exhibited good rate capability with larger discharge capacities than those of the electrode prepared by the sol–gel method, due to the increment of electrode thickness (0.6 μm → 4.2 μm) and the simultaneous deposition of conducting and binding materials with Li 4 Ti 5 O 12 particles. A cell consisting of the microarray Li 4 Ti 5 O 12, lithium metal anode, and poly(methyl methacrylate) gel electrolyte was successfully operated at 1.55 V and had the discharge capacity of 105.4 μ A h cm-2.
