Materials Data on CuF2 by Materials Project

CuF2 is zeta iron carbide-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Cu2+ is bonded to six equivalent F1- atoms to form a mixture of corner and edge-sharing CuF6 octahedra. The corner-sharing octahedra tilt angles range from 50–52°. There are a spread of Cu–F bond distances ranging from 1.95–2.27 Å. F1- is bonded in a distorted trigonal planar geometry to three equivalent Cu2+ atoms.

On the electronic structure and spectrum of CuF2 and CuCl2

Results are reported from SDCI and CPF ab initio computations for the ground and low-lying states of CuF2 and CuCl2. A large Gaussian basis set with functions up to the g level is employed, and the results are presented in tables and characterized in detail. Particular attention is given to the bond distances and force constants for the ligand-field states and the bond distances for the charge-transfer states. Good agreement is obtained between the CPF and SDCI values and with published experimental data.

High energy density primary batteries

By the use of fractional factorials, paths of steepest ascent and direct comparison experimentation, performance characteristics of the CuF2/LiAsF6-MF/Li electrochemical system were optimized under conditions of temperature environment, discharge rate, active stand, and use of anhydrous cathodes. Two hundred ampere-hours/lb of CuF2 and 600 watt-hours/lb of CuF2 were achieved in anhydrous cells at plus 40 C and at a discharge rate of 10 ma sq cm. Electrical performance is primarily altered by temperature and discharge rate; however, other factors such as cathode water content, cathode conductor content, separator thickness, and the use of SO2 gas also have significant effects.
