Atomic‐Scale Tracing of Lithium Trapped in Copper Current Collectors

open access: yesAdvanced Energy Materials, EarlyView.
Does lithium diffuse into the copper current collector during cycling in lithium‐metal batteries? This study unveils, at the atomic scale, that lithium is trapped at grain boundaries and junctions, already after only one plating/stripping cycle. After three and more cycles, the copper foil surface becomes nanocrystalline and oxidized.

Ultrathin Aluminum–Air Batteries via Hygroscopic Electrolytes for Continuous Operation of Imperceptible On‐Skin Electronics

open access: yesAdvanced Energy Materials, EarlyView.
This study presents ultrathin, high‐capacity aluminum‐air batteries (AABs) for self‐sustaining, skin‐conformal electronics. By utilizing ambient moisture and oxygen alongside a LiCl‐based hygroscopic hydrogel electrolyte, the design significantly reduces battery thickness while preventing dehydration and Al self‐corrosion.

Reconstructing Solvation Structure via Strongly Nucleophilic Anions for High‐Rate and Low‐Temperature Graphite||LFP Pouch Cells in PC‐Based Electrolyte

open access: yesAdvanced Energy Materials, EarlyView.
A nucleophilic‐anion‐regulated solvation strategy is developed for Propylene carbonate (PC)‐based electrolytes, where NO3−${\mathrm{NO}}_3^ - $ preferentially enters the Li+ solvation sheath and replaces coordinated PC molecules without sacrificing ionic conductivity.

A Fluorine‐Free, Low Ion Pair Electrolyte for Transition Metal‐Free and Halogen‐Free Sodium Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Fluorine‐containing electrolytes dominate modern rechargeable batteries, yet the fundamental design principles for fluorine‐free systems remain largely unexplored. We demonstrate that fluorine‐free electrolyte chemistry can simultaneously achieve long cycle life, fast charging, and stable interphase formation in sodium‐ion batteries.

Synergistic Anode Engineering for Aqueous Aluminium Ion Batteries: From Mechanistic Understanding to Computationally Accelerated Design

open access: yesAdvanced Energy Materials, EarlyView.
Mechanistic anode engineering for aqueous aluminium‐ion batteries is discussed through alloying and microstructure control, surface/interface engineering, and electrolyte modification to regulate ion transport, suppress dendrites, passivation, hydrogen evolution, and side reactions, highlighting standardisation, computational acceleration, and ...
