Li‐Ion Battery Anodes Combining Intercalation and Plating Energy Storage Mechanisms through SiOx/C Coated Graphite

open access: yesAdvanced Functional Materials, EarlyView.
A thin SiOx/C coating enables graphite to stably support Li intercalation and Li plating in a hybrid anode. Paired with an optimized localized high‐concentration electrolyte, the full cell achieves 584 mAh g−1 and 86% capacity retention after 500 cycles, highlighting a practical route toward higher‐energy lithium‐ion batteries.

Electrolyte‐Induced Cu+ Preservation Results in a Selectivity Switch of Electrocatalytic CO2 Reduction at a Copper‐Organic Framework as Electrocatalyst

open access: yesAdvanced Functional Materials, EarlyView.
The active role of KCl as a neutral electrolyte enables switching the selectivity on a Cu organic framework from C1 to C2+ products during electrocatalytic CO2 reduction. ABSTRACT We introduce a copper‐nicotinate (Cu‐NA) framework as a halogenide‐stabilized Cu+/Cu0 pre‐catalyst for electrocatalytic CO2 reduction with high C2+ selectivity in a “neutral”

A High Capacity Li-Ion Cathode: The Fe(III/VI) Super-Iron Cathode

open access: yesEnergies, 2010
A super-iron Li-ion cathode with a 3-fold higher reversible capacity (a storage capacity of 485 mAh/g) is presented. One of the principle constraints to vehicle electrification is that the Li-ion cathode battery chemistry is massive, and expensive ...

Redirecting Nano‐Silicon Agglomeration: Dual‐Carbon Design Triggers Self‐Adaptive Nanoporous Si Sponge for Enhanced Lithium Storage

open access: yesAdvanced Functional Materials, EarlyView.
This study addresses silicon anode degradation using an engineered nSi/Gr/C dual‐carbon matrix. By restricting SEI infiltration, the architecture redirects silicon agglomeration into a beneficial structural self‐adaptive activation. During cycling, silicon nanoparticles self‐organize into a resilient nanoporous sponge. This dynamic network accommodates

Water Adsorption‐Induced Color Sensor: Insight Into the Sensing Mechanism and Interfacial Engineering for Improved Responsiveness

open access: yesAdvanced Functional Materials, EarlyView.
We report a unique color‐sensing phenomenon of a TiO2/SbSI:Sb2S3 device utilizing X‐ray absorption. Based on the revealed penetration and adsorption of water onto TiO2, we successfully improved the color response speed and sensitivity by incorporating a hydrophilic polymer interlayer, thereby opening up opportunities for photodetection applications ...
