In Situ UV-Vis Analysis of Polysulfide Shuttling in Ionic Liquid-Based Li-FeS2 Batteries

Aliya S. Lapp et al.

Summary: In this study, a combination of in situ and ex situ UV-Vis spectroscopy is used to investigate the formation and shuttling of polysulfides in Li-FeS2 batteries. The results show that PS shuttling can be significantly reduced when an ionic liquid electrolyte is used instead of a conventional organic electrolyte, and changing the Li salt anion in the ionic liquid electrolyte effectively suppresses PS shuttling. The majority of PS shuttling occurs during the first cycle, and the total amount of PSs formed using the ionic liquid electrolyte is approximately double the amount shuttled.

Fe K-edge x-ray absorption spectroscopy of corrosion phases of archaeological iron: results, limitations, and the need for complementary techniques

Hayley Simon et al.

Summary: Data analysis methods for iron x-ray absorption spectroscopy can provide extensive information about the oxidation state and co-ordination of an Fe-species. However, the extent to which techniques developed using a single-phase iron sample may be applied to complex, mixed-phase samples formed under real-world conditions is not clear. The study used a combination of pre-edge fitting and linear combination analysis to characterize the XANES for archaeological iron corrosion samples and compared the results with phase compositions determined by synchrotron x-ray powder diffraction.

FeS2 encapsulated with mesoporous carbon for high-performance lithium-ion batteries

Heguang Liu et al.

Summary: A strategy of introducing mesoporous carbon (MPC) to obtain a FeS2/MPC composite electrode for lithium-ion batteries (LIBs) was proposed in this study, resulting in a significant improvement in electrochemical performance compared to pristine FeS2. The discharge capacity of the composite electrode reached 650 mAh g(-1) at 0.5 C current density, demonstrating its potential for practical applications.
