Atomic‐Layer‐Deposited ZnF2 on Aluminum Enabling In Situ NaF/Na–Zn Interphase for Robust Anode‐Free Sodium Batteries

open access: yesAdvanced Energy Materials, EarlyView.
“Sodiation of an ultrathin ALD‐ZnF2 layer on an Al current collector generates a sodiophilic Na–Zn alloy and a NaF‐rich SEI, enabling uniform Na deposition and highly reversible anode‐free sodium batteries.” ABSTRACT Achieving high‐energy‐density “anode‐free” sodium batteries remains a daunting challenge due to rapid capacity decay caused by poor ...

A Large Scale Multi‐Modal Workflow for Battery Characterization: From Concept to Implementation

open access: yesAdvanced Energy Materials, EarlyView.
Isolated characterization techniques produce independent datasets and single‐property insights. However, progressively more holistic interpretations of battery‐material behavior is needed in the future. Here we demonstrate a coordinated multimodal workflow enabling the correlation of heterogeneous datasets and the construction of multidimensional ...

SOC Mismatch–Driven Inter‐Particle Synchronization via Internal Li‐Ion Transfer: An Unrecognized Electrode‐Emergent Degradation Pathway in Ni‐Rich Composite Cathodes

open access: yesAdvanced Energy Materials, EarlyView.
Composite cathode degradation is not merely the sum of its particles. Kinetically mismatched populations develop state‐of‐charge differences that drive spontaneous internal Li‐ion transfer; the accompanying transient currents accelerate surface degradation.

Nano‐Heterostructured TiO2‐TiO‐TiN/MoO3‐x‐Mo2N Composite LIB Anode With Enhanced Li+ Storage via Glycine‐assisted Anodization and Cathodic Deposition

open access: yesAdvanced Energy Materials, EarlyView.
A scalable, binder‐ and additive‐free strategy combining glycine‐assisted anodization and cathodic deposition is developed to fabricate a nano‐heterostructured composite LIB anode directly on titanium. Benefiting from its fully electrochemically active thick architecture, the anode delivers an outstanding areal capacity of 2639 µAh cm−2, nearly ...

Facilitated Phase Transformation for Improved Performance of Earth‐Abundant Disordered Rocksalt Materials

open access: yesAdvanced Energy Materials, EarlyView.
As demand for Li‐ion batteries grows, Mn‐rich disordered rocksalt (DRX) oxides offer a sustainable, low‐cost alternative to scarce Ni and Co. During cycling, Mn‐rich DRX materials transform into a partial spinel‐like phase (𝛿) that improves rate capability and capacity.
