Optimizing the Structure/Texture Coupling of Carbon Xerogels for High‐Performance Anodes of Sodium‐Ion Batteries in Glyme‐Based Electrolytes

Battery Energy, Volume 5, Issue 2, March 2026.
Carbon xerogels synthesized via a microwave‐assisted process were carbonized in the range of 1000°C–2800°C and evaluated as anodes for next‐generation sodium‐ion batteries. The material prepared at 1800°C showed optimal structural and textural properties and excellent electrochemical performance. Potential profile analysis provided insights into sodium

Tunable Crystal Orientation and Particle Size Enable Stable Co‐Free LNMO Cathode

EcoMat, Volume 8, Issue 3, March 2026.
The truncated octahedral LNMO with exposed (111)/(100) crystal planes, moderate particle size, and optimal Mn4+/Mn3+ has been achieved through tuning sol pH and gel calcination temperature via sol–gel method. The synergistic effects of these characteristics promote superior stability and fast ionic diffusion capability of LNMO. These findings highlight

Interface Issues of Inorganic Solid‐State Electrolytes in Secondary Magnesium Batteries

Rare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Solid‐state magnesium batteries (SSMBs) have gained significant attention as promising candidates for next‐generation safe energy storage systems because of the abundance of magnesium (Mg) in the earth's crust, superior energy density, and inherent nonflammability.
