“…39–42 The R ct values of FeNi@NCNF-1 (118.3 Ω), FeNi@NCNF-2 (81.7 Ω), and FeNi@NCNF-3 (192.1 Ω) are much lower than those of pure NCNFs (1814.2 Ω), demonstrating that the introduction of FeNi alloys remarkably enhances the electronic conductivity of the entire electrode. The relational lithium-ions diffusion coefficients ( D Li + ) can be determined by the following formula: 43–45 D Li + = 0.5 R 2 T 2 / n 4 A 2 F 4 C 2 k 2 Z re = K 0 + k·w −1/2 …”

H x CrS 2−δ is produced by the proton exchange of NaCrS 2 and features alternating layers of crystalline and amorphous lamella. It exhibits superior performance as a Na-ion battery electrode compared with its parent compound with faster Na + diffusion, higher capacity, and better cyclability. This work explores the nature of the unique biphasic structure of H x CrS 2−δ using both powder and single-crystal X-ray diffraction, as well as electron microscopy. Additionally, ex situ characterizations using X-ray absorption spectroscopy, X-ray total scattering, and magnetometry are employed to study the mechanism by which this superiority arises. These reveal that migration of Cr does not impede battery performance and may, in fact, be crucial to the observed performance improvements. These studies show that Cr redox is not only possible but abundant in H x CrS 2−δ while accessing it in NaCrS 2 at lower voltages results in irreversible structural transitions that limit cycling stability. Additionally, we highlight the potential of biphasic structures such as H x CrS 2−δ to enable high performance in energy storage electrodes.
