Vacancy‐Suppressed Garnet Electrolytes for Durable Solid‐State Batteries

open access: yesAdvanced Science, EarlyView.
A Li/O‐rich sintering strategy effectively suppresses intrinsic lithium and oxygen vacancies in cubic garnet electrolytes, yielding a dense and stable microstructure. The vacancy‐controlled electrolyte exhibits enhanced interfacial and air stability, enabling long‐term solid‐state battery cycling and providing a general design principle for defect ...

Boosting Fast‐Charging Performance of Ni‐Rich NCM9055 Cathodes with Nb2O5 Dual Functional Modification

open access: yesAdvanced Science, EarlyView.
A dual‐functional Nb2O5 modulation strategy is reported to overcome kinetic limitations in Ni‐rich cathodes. The formation of LiNbO3 phase at the grain boundary of the polycrystalline NCM9055 cathode preserves a radially aligned microstructure and establishes fast lithium‐ion pathways.

Transition metal fluorides for lithium-fluoride ions battery

open access: yes, 2014
This thesis presents an in-depth investigation of the conversion reaction mechanism of cobalt difluoride (CoF2) as the cathode material in lithium half-cell and the synthesis of nickel-cobalt difluoride [NixCo(1-x)F2]. The use of CoF2 and thorough understanding of the conversion reaction mechanism of CoF2 was first examined by mixing CoF2 with ...

Bioinspired Microphase‐Engineered Binders for Silicon Anodes

open access: yesAdvanced Science, EarlyView.
Inspired by the tough exoskeleton of Phloeodes diabolicus, a bio‐based binder featuring LRA–click chemistry and hierarchical crosslinking forms well‐defined microphase‐separated structures that enable robust silicon anodes. This system promotes the formation of a LiF–rich, ultrathin SEI (∼17 nm) with high modulus and ionic conductivity, ensuring long ...

Absorption‐Dominant Electromagnetic Interference Shielding of Ti3C2Tx MXene‐Coated and Fe3O4‐Integrated TPMS Composites with Coupled Gradient Conductivity and Size‐Graded Structure

open access: yesAdvanced Science, EarlyView.
A functionally driven variable‐cell size and gradient‐conductive coated TPMS structure was developed. Accordingly, stepwise longitudinal gradient impedance was realized, achieving absorption‐dominant EMI shielding (absorptivity≈0.85) with an EMI SET of ≈ 59 dB, for 10 mm‐thick composites. Further increasing the thickness of composites to 20 mm achieved
