Sodium ion storage in reduced graphene oxide [PDF]

, 2016
The performance of few-layered metal-reduced graphene oxide (RGO) as a negative electrode material in sodium-ion battery was investigated. Experimental and simulation results indicated that the as-prepared RGO with a large interlayer spacing and ...

A Dual‐Functional Electrolyte Additive for Highly Reversible Zinc‐Ion Batteries

Advanced Functional Materials, EarlyView.
This study introduces tetrabutylammonium bromide (TBAB) as a dual‐function additive for aqueous zinc‐ion batteries. TBAB disrupts the hydrogen‐bond network of water while TBA+ adsorbs on Zn to improve interfacial wettability and regulate Zn2+ flux, resulting in suppressed dendrite growth and parasitic reactions. This synergy extended the lifespan of Zn|

Hierarchical MXene‐Derived NTP/C Nanohybrids for Cryogenic Sodium‐Ion Batteries

Advanced Functional Materials, EarlyView.
A hierarchical MXene‐derived NaTi2(PO4)3/C nanohybrid enables efficient sodium‐ion storage down to −40°C by integrating fast ion–electron transport pathways with an ether‐based electrolyte. The system promotes dominant pseudocapacitive behavior and forms a robust inorganic‐rich SEI, collectively mitigating kinetic and interfacial limitations, thereby ...

Interlayer Expansion of Bulk MoS2 via Top‐Down Organic Pillaring Enables Tunable Li+ Intercalation and Controlled Solvent Co‐Intercalation

Advanced Functional Materials, EarlyView.
Top‐down organic pillaring expands the interlayer spacing of bulk‐sized MoS2 particles while preserving the bulk morphology. Operando X‐ray diffraction and electrochemical dilatometry show that MoS2‐bulk undergoes solvent co‐intercalation in diglyme electrolyte, causing large structural expansion, while pillared, expanded MoS2 suppresses solvent uptake
