Characterization and Reporting Protocols for Structural Power Composites: A Perspective

open access: yesAdvanced Energy Materials, EarlyView.
Here, the issues for testing and reporting on structural power composites are described: multifunctional materials that can carry loads while providing electrical energy. As well as proposing best practice, the development of a “universal coupon” is recommended for studying these materials and any interactions that occur between the two functions ...

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.

Tuning Cation (Dis)Order in Cr‐Based Li‐Excess Oxide Cathode Materials to Improve Li+ Transport Properties

open access: yesAdvanced Energy Materials, EarlyView.
Partially disordered Cr‐based Li‐rich oxides are developed, featuring ordered, layered‐like environments integrated through a common oxygen sublattice with cation‐mixed regions. This activates new Li+ diffusion channels, enabling these cathodes to be used in their as‐synthesized form with micron‐sized particles.
