Na-Ion

Na[B(pp)2]

relatively stable to atmospheric conditions, form good SEIs, and yield better electrochemical performance than NaPF6. The Na[B(pp)2] salt (Figure, top) is tolerant toward air and water with a conductivity over 8 mS/cm (1 M in EC:DEC 1:1 v/v) and promising stability against sodium metal (Figure, bottom). It also shows good initial electrochemical performance in a ca. Na0.79Ni0.27Mn0.42Mg0.15Ti0.17O2//hard carbon cell.
