New Design Strategy Enhances Stability of High-Voltage Sodium-Ion Battery Cathodes

Researchers have developed a quantitative design strategy to improve the cycling stability of high-voltage sodium-ion batteries by addressing ionic field strength disparities among transition-metal ions in cathodes. They introduced an ionic field strength disparity coefficient (η) to quantify these disparities, potentially enabling better battery performance. This approach focuses on O3-type layered oxide cathodes and could advance sodium-ion battery technology.
