Title: Structure and Electrochemistry of Copper Fluoride Nanocomposites Utilizing Mixed Conducting Matrices

Abstract

Near-theoretical utilization of high-energy-density CuF{sub 2} positive electrode materials for lithium batteries was enabled through the use of nanocomposites consisting of 2-30 nm domains of CuF{sub 2} within a mixed ionic + electronic conducting matrix of a metal oxide. Small but significant crystallographic changes to the core crystal of the CuF{sub 2} were found to occur in all oxide-based matrices. These modifications to the core crystal and the surrounding matrix were investigated through a host of characterization methods, including XRD, XPS, and XAS. This new approach to the enablement of the anhydrous CuF{sub 2} is distinctly superior in performance to that of macro CuF{sub 2} or CuF{sub 2} nanocomposites utilizing carbon as a matrix, the latter of which is also introduced herein for the first time.
