Physics‐Guided Descriptors Enable Data‐Efficient Prediction of Battery Coulombic Efficiency

Advanced Science, EarlyView.
This work integrates multiscale simulations with data‐driven approaches to predict Coulombic efficiency (CE). Multiscale simulations of battery systems are performed to extract Physics‐Guided descriptors and construct a dataset. Machine learning models trained on this dataset are then subjected to interpretable analysis to identify the most influential

In Situ Alkali Metal Exfoliation‐Coupled Dilute CO2 Electrolysis to Synthesize Interlayer‐Expanded Graphite for High‐Rate Lithium Storage

Advanced Science, EarlyView.
Converting CO2 into advanced carbon materials capable of meeting the rapid lithium storage demands of lithium‐ion batteries creates a mutually beneficial scenario for both energy and environmental sectors. Here, we propose a stepwise CO2 electrolysis approach to transform dilute CO2 into interlayer‐expanded graphite using molten salt electrolyzers ...

From thin-film to high-loading silicon anodes: buried interfacial contact instability in all-solid-state batteries

Frontiers in Mechanical Engineering
Silicon is one of the most attractive anode materials for all-solid-state batteries (ASSBs) because of its high theoretical capacity, low lithiation potential, and abundance.

Unveiling Mechanisms of SEI Formation and Sodium Loss in Sodium Batteries via Interface Reactor Sampling

Advanced Science, EarlyView.
An “Interface Reactor” strategy boosts simulation stability by 2–3 orders of magnitude, enabling stable 100 ns molecular dynamics of electrode‐electrolyte interfaces. Distinct SEI formation mechanisms are revealed: mixed co‐formation in carbonates versus surface‐energy‐controlled NaF crystallization in ethers. Metadynamics simulations further elucidate

Stacking Pressure‐Driven Interfacial Dynamics in Anode‐Free Solid‐State Lithium Batteries

Advanced Science, EarlyView.
Using a three‐electrode setup, it is found that stacking pressure improves both anode and cathode interfaces but more effectively stabilizes the anode. Under low pressure, a sudden anode resistance rise indicates contact loss. Higher pressure delays this via Li creep and plastic deformation, maintaining interfacial contact.

Unsuccessful Coupling of Weakly Coordinating Anion–Based Mg Salts and Alkoxyalkylamine Solvents for Rechargeable Mg Battery Application: Trace Water‐Driven Interfacial Failure

Advanced Science, EarlyView.
Combining recently established two ground‐breaking concepts, the adoption of WCAs and the use of alkoxyalkylamine‐based solvents in electrolyte formulations for rechargeable magnesium metal batteries, has led to unexpectedly unsuccessful electrochemical Mg plating/stripping performance. Comprehensive experimental and computational analyses revealed the
