Electronic conductor-free FeF2 films deposited by pulsed laser deposition (PLD) were studied as potential cathode materials for Li-ion batteries. The correlation between microstructural evolution and electrochemical cycling of PLD FeF2 films was investigated. Cross-sectional transmission electron microscopy (X-TEM) of the films indicates that they are composed of particles varying in size between 10 and 50 nm. 20-50 nm particles were initially deposited on the sample substrate and were not cycled, irrespective of film thickness and applied C-rate; 10 nm particles were cycled at low C-rates. Cross-sectional TEM of delithiated films shows that the reconversion process starts from the bottom to the top of the film by forming FeF2 on the 20-50 nm FeF2 particles. Galvanostatic measurements show that thinner FeF2 films have higher capacities and expansion percentages than thick films, but the measured capacity of these films is still less than the theoretical capacity. These results suggest that the cycling performance of PLD FeF2 is limited by electron transport and that the addition of an electronic conductor will increase the cycling capacity of FeF2 films.
