Sodium Ion Conducting Ceramics for Sodium Ion Batteries
, 2019 The overwhelming demand of energy storage technologies has forced the scientific community to look beyond the commercially available options such as lithium ion batteries. As one of a potential alternative, sodium ion battery technology works in a similar way but provides the advantage of abundant and readily available raw materials at low cost.

Understanding Sodium-Ion Battery Degradation with a Data-Driven Approach
Sodium-ion (Na-ion) batteries offer a cost-effective and safer alternative to lithium-ion systems, yet real-time health monitoring remains challenging due to slow diagnostics and complex degradation mechanisms. This work presents a digital-twin framework

Advanced Science, EarlyView.Ti substitution stabilizes Co‐free high‐Ni layered oxides through both structural and electronic effects. TiO6 octahedra act as compensatory structural units that help interrupt cooperative Jahn–Teller distortion and suppress detrimental phase transitions, while the electron‐withdrawing inductive effect of Ti stabilizes the oxygen lattice. As a result,

Single-Phase Solid-Solution Reaction Facilitated Sodium-Ion Storage in Indium-Substituted Monoclinic Sodium-Iron Phosphomolybdate Cathodes [PDF]
Despite being a compelling alternative to the existing lithium-ion battery technology, the unavailability of cathodes with high energy density and capacity poses a key challenge toward the wider adaption of sodium-ion batteries (NIB).

Advanced Science, EarlyView.An ultrafast (2‐minute), gas‐free chemical pre‐sodiation strategy using Na‐benzophenone is developed to compensate for initial sodium loss in calcium vanadate (CaV8O20). Driven by the Ca2+ ‘spectator effect’, the framework enables highly reversible, quasi‐zero‐strain solid‐solution sodium storage, explicitly bypassing destructive conversion reactions ...

Architecting Phase‐Selective Interlayers for Stable SiOx Lithium Storage via Dual‐Function Design
Advanced Science, EarlyView.Silicon anodes offer high capacity but suffer severe volume expansion. Silicon monoxide (SiO) buffers expansion, yet uncontrolled lithiation irreversibly consumes lithium as Li2O and oxygen‐rich silicates. Here, we design a layered SiOx featuring a phase‐selective conductive interfacial interlayer (PSCII), i.e., a Li4SiO4‐rich, ion‐accessible ...
