Scaling of Planar Sodium‐Nickel Chloride Battery Cells to 90 cm2 Active Area
Large planar Na β′′ alumina electrolytes are prepared by tape‐casting and die‐pressing. These ceramic electrolytes are used to prepare planar sodium‐nickel chloride cells with 90 cm2 active area, providing a high capacity of 7 Ah. Successful cell cycling is demonstrated at 300 °C at rates up to C/4 (20 mA cm−2) for a cumulative capacity of 3.6 Ah cm−2.

Moving Beyond 99.9% Coulombic Efficiency for Anode‐Free Sodium Metal Battery
Iron‐anchored carbon nanotubes (CNT‐Fe) are developed as a 3D sodiophilic host for anode‐free sodium metal batteries. The Fe nanoparticles significantly enhance sodium adsorption and ensure uniform deposition, enabling an exceptional 99.9% Coulombic efficiency over 1100 cycles and long‐term stability in high‐loading full cells.

Lithium‐ion battery anodes that maintain good performance and excellent stability under high temperature conditions. Silicon oxide (SiO) has great potential as a high‐capacity anode for lithium‐ion batteries, but its practical use is limited by excessive volume expansion (>200%) and rapid capacity fade, especially at high temperatures.

We propose a universal “x → 0 → 1” regeneration route: mechanochemical delithiation converts spent LixFePO4 of any degradation level to FePO4, erasing batch variance; 35‐s flash relithiation yields uniform LiFePO4 with near‐identical capacity, suppressing grain growth and cutting energy andtime by >90% versus furnace sintering, overcoming unpredictable
