Synergistic Effects of Solid Electrolyte Mild Sintering and Lithium Surface Passivation for Enhanced Lithium Metal Cycling in All‐Solid‐State Batteries

Advanced Science, EarlyView.
This study proposes a synergistic strategy combining mild sintering of solid electrolyte pellets with lithium metal surface passivation, effectively suppressing dendrite growth, and enhancing interfacial stability. This approach doubles the critical current density of symmetric cells (1.1 to 2.2 mA cm−2) and extends full cells cycle life at 1 mA cm−2 ...

Ion‐Confinement‐Assisted Erasure Purifies Oxidized MXene for Reuse

Advanced Science, EarlyView.
An erasure‐purification strategy removes surface‐derived TiO2 from oxidized Ti3C2Tx MXene by ion‐confinement‐induced interfacial conversion to soluble titanates, followed by brief acid washing. The scalable process enables approximately 70% material recovery, restores electrical conductivity, and recovers functional performance, including high ...

Breaking the Thick Electrode Paradox With an in situ VS2@V2CTx MXene Heterostructure for High‐Areal‐Capacity Batteries

Advanced Science, EarlyView.
This work pioneers an in situ gas‐phase conversion strategy to construct VS2@V2Tx heterostructures within a MWCNT network. The integrated architecture establishes interpenetrating electron/ion highways, enabling an ultra‐thick electrode (300 µm) to achieve a high areal capacity of 13.6 mAh cm−2 with exceptional cycling stability, demonstrating great ...

A Functionality‐Graded Cathode Electrolyte Interphase Enables Ultra‐Long Cycling Stability in Aqueous Zn–Mn Batteries

Advanced Science, EarlyView.
Through the interfacial reaction of KH2PO4, a functionally graded CEI with hydrated, organic, and inorganic layers is constructed. This suppresses interfacial water corrosion, mitigates volume stress, and promotes charge carrier transport, achieving superior battery stability.

Metastable Structure for Ultra‐Sustainable, High Capacity and Kinetics‐Enhanced Magnesium‐Ion Battery

Advanced Science, EarlyView.
A metastable‐phase evolution strategy is proposed for magnesium‐ion batteries, enabling the in situ formation of a metastable MgxT‐VS4 cathode during cycling. The metastable state reshapes Mg2+ storage kinetics and enhances structural stability, offering a new design paradigm for multivalent ion battery cathodes.

Quasi‐Antipolar Nanoclusters Driven Superior Energy Storage in High‐Entropy Relaxor Ferroelectrics

Advanced Science, EarlyView.
Quasi‐antipolar nanoclusters are engineered in lead‐free NaNbO3‐based high‐entropy relaxors that weaken polar nanoregion coupling and induce distinct ferroelectric transition under high fields to enable desirable polarization response. This breakthrough system achieves ultrahigh recoverable‐energy‐density (≈18.3 J cm−3), efficiency (≈91.5%), and ...
