Wildcat Discovery Technologies has recently developed the first rechargeable CuF2 material with demonstrated initial reversible capacity >240 mAh/g. To the best of our knowledge, CuF2 has not shown a reversible conversion reaction presumably due to the fact that the Cu nanoparticles after the lithiation are too large and the insulating LiF prevents electron migration to convert back to CuF2 (The reaction pathway for discharge is CuF2 à Cu + 2LiF). Our approach was to utilized high-throughput combinatorial research to improve the conductivity of CuF2 by surface coating. After evaluation hundreds of coatings, a two-step process of making a transition metal oxide coating allowed for 15 rechargeable cycles with greater than 80% retention (Fig.1b). To build on these results and improve cycling performance a better understanding of the local environment of the Cu and the metal oxide coating is needed. We first utilized synchrotron X-ray absorption spectroscopy, at the Argonne National Laboratory. to provide a better understanding of the local atomic structure and phase progression of the metal oxide coated and uncoated CuF2. The results suggest that the metal oxide coating helps in the reversibility of the Cu to CuF2 conversion but is not electrochemically active (no coordination change or oxidation change). Additionally, we utilized high resolution aberration corrected transition electron microscopy to visualize the distribution of Cu and LiF with that of the metal oxide coating. By utilizing both techniques we are able to improve our understanding of the metal oxide coating which will help guide the future direction of the conversion material.
