Summary: Despite the broad range of inorganic cathode materials developed to date, there is a lack of studies on the correlation between the electronic structure and performance. This study suggests that the symmetricity/asymmetricity of e(g)/t(2g) orbitals in redox-active elements is crucial in determining the Jahn-Teller distortion of LiM0.125Mn1.875O4 spinel-type cathode materials. The presence of Mn3+ ions during the discharging process leads to poor structural durability and electrochemical performance, and this limitation can be overcome by adding carefully selected Ni2+ dopants.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.
