Synergetic Lattice and Surface Engineering: Stable High‐Voltage Cycle Performance in P3‐Type Layered Manganese Oxide

open access: yesAdvanced Energy Materials, EarlyView.
A dual lattice‐surface strategy employing NaTi2(PO4)3 is adopted to enhance the performance of P3‐type Na0.67[Zn0.3Mn0.7]O2, whereby Ti stabilizes the bulk lattice and surface P species mitigate degradation, collectively improving high‐voltage cycling stability, Na+ diffusion, and oxygen redox reversibility through synergistic structural and ...

Separating Nucleation and Growth: High‐Overpotential Pretreatment Pulses for Sodium‐Metal Electrodes

open access: yesAdvanced Energy Materials, EarlyView.
During conventional galvanostatic cycling sodium metal growth/removal occurs unevenly with some parts forming large and deep pits, as well as mossy sodium growth, and the rest of the surface left mostly non‐activated. This issue can be solved using short high‐overpotential pretreatment pulses during the first cycle leading to well‐distributed ...

Unraveling Asymmetric Macroscopic Reaction Dynamics in Solid‐State Li–S Batteries During Charge–Discharge Cycles: Visualizing Ionic Transport Limitations with Operando X‐Ray Computed Tomography

open access: yesAdvanced Energy Materials, EarlyView.
Operando X‐ray computed tomography visualizes evolving through‐thickness sulfur‐lithiation distribution in solid‐state Li–S battery (SSLSB) cathodes during charge‐discharge cycles. These observations reveal that macroscopic ionic transport severely limits the rate capability, and charging exhibits significantly more pronounced reaction heterogeneity ...

Exploring the Inhomogeneous Nature of Li Intercalation and Li Plating on Graphite Anodes—An Experimental Study Combining Inert Gas High‐Resolution Light Microscopy with Colorimetric and Machine Learning‐Based Image Analysis

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Graphite anode lithiation and lithium plating are explored using high‐resolution light optical microscopy under inert gas atmosphere. Colorimetric analysis and machine learning reveal lithiation stages depending on C‐rate and state‐of‐charge. With increasing C‐rate, heterogeneity of lithiation increases, resulting in up to three phases coexisting in ...
