A Novel Quantification Method for High Voltage Structural Evolution in Sodium and Lithium Layered Oxides

open access: yesAdvanced Energy Materials, EarlyView.
High‐voltage cycling of layered alkali transition metal oxides in Li‐ and Na‐ion cells increases energy density but diminishes lifetime. A novel XRD‐analysis method, centered on the stacking factor “z”, is developed to quantify the stacking fractions in the OP hybrid structure.

Trifluoracetic Acid‐Driven (002) Facet Engineering of Zn Metal Powder Anodes for High‐Performance Aqueous Zinc‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
A selective surface engineering strategy is presented for zinc metal powder (ZnMP) anodes in aqueous zinc‐ion batteries. Trifluoroacetic acid treatment enriches the exposure of (002) planes, forming a stepped hexagonal morphology that suppresses hydrogen evolution and dendrite growth.

Addressing the Challenges of 3C‐SiC—Synergetic Effect of Conductive Additives on the Performance of SiC as Anode Material for Lithium‐Ion Batteries

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
This study explores the role of conductive carbon black (CB) in enhancing the electrochemical activity of 3C‐SiC anodes for lithium‐ion batteries. By isolating the individual contributions of SiC and CB, the work demonstrates a synergistic effect that enables active lithiation in SiC, offering new insight into composite electrode design for improved ...

Metastable Crystalline Cobalt Iron Oxide Nano‐Flakes with Antiferromagnetic/Ferrimagnetic Composition Mosaicity

open access: yesAngewandte Chemie, EarlyView.
Through precursor co‐precipitation and mild calcination, a metastable interface‐rich cobalt iron oxide with unique magnetic properties was synthesized. Due to compression of the lattice parameter in the iron‐rich phase and the multitude of interfaces, an exchange bias was created, usually not known for such powder samples.
