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 ...

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.

Transition Metal Compounds for Aqueous Ammonium‐Ion Batteries: Storage Mechanisms and Electrode Design

Advanced Science, EarlyView.
Aqueous ammonium‐ion batteries leverage hydrogen‐bond‐mediated NH4+ storage in tunable transition metal compounds. Despite progress in Mn‐, V‐, Mo‐, and W‐based compounds, 2D LDHs, and MXenes, challenges like structural instability and slow kinetics persist. Future advances require robust host design, mechanistic understanding via operando studies, and
