Phosphorus addition could unlock safer, high-performance sodium-ion batteries

Researchers at Kogakuin University have discovered that adding phosphorus (P2O5) to sodium-yttrium-silicate glasses significantly enhances their performance as solid electrolytes for next-generation sodium-ion batteries. This improvement arises from the formation of the high-performance Na5YSi4O12 crystal phase, which promotes high ionic conductivity and stability, making sodium-based batteries a safer and promising alternative to lithium-ion technologies. However, the effects of phosphorus on the glass structure and its location after crystallization had not been fully understood.
