Title: Three-Dimensional Solid-State Lithium-Ion Batteries Fabricated by Conformal Vapor-Phase Chemistry

Abstract

Three-dimensional thin-film solid-state batteries (3D TSSB) were proposed by Long et al. in 2004 as a structure-based approach to simultaneously increase energy and power densities. Here, we report experimental realization of fully conformal 3D TSSBs, demonstrating the simultaneous power-and-energy benefits of 3D structuring. All active battery components—electrodes, solid electrolyte, and current collectors—were deposited by atomic layer deposition (ALD) onto standard CMOS processable silicon wafers microfabricated to form arrays of deep pores with aspect ratios up to approximately 10. The cells utilize an electrochemically prelithiated LiV 2O 5 cathode, a very thin (40–100 nm) Li 2PO 2N solid electrolyte, and a SnNx anode. The fabrication process occurs entirely at or below 250 °C, promising compatibility with a variety of substrates as well as integrated circuits. The multilayer battery structure enabled all-ALD solid-state cells to deliver 37 μAh/cm 2·μm (normalized to cathode thickness) with only 0.02% per-cycle capacity loss. Conformal fabrication of full cells over 3D substrates increased the areal discharge capacity by an order of magnitude while simulteneously improving power performance, a trend consistent with a finite element model. Furthermore, this work shows that the exceptional conformality of ALD, combined with conventional semiconductor fabrication methods, provides an avenue for the successfulmore » realization of long-sought 3D TSSBs which provide power performance scaling in regimes inaccessible to planar form factor cells.« less

Figure 1 Figure 1: Methods of improving energy storage metrics for thin film solid state batteries. Increasing the electrode thickness scales energy density at the expense of power density due to the rapid increase in the characteristic diffusion time for ions in the thick electrode. Fabricating TSSBs in a 3D structure bothmore » increases areal material loading and increases power performance through a decrease in the internal current density due to the larger internal surface area.« less
