Sodium bis(oxalato)borate Usage And Synthesis

Description

Sodium bis(oxalato)borate (NaBOB) salt was first synthesized by Zavalij et al. in 2003. It could be used as the electrolyte salt in sodium-ion batteries. A nonflammable and fluorine-free electrolyte based on NaBOB dissolved in TMP disclosed promising results regarding the electrolyte ionic conductivity (5 mS cm–1 at room temperature) and electrochemical performance in sodium-ion full cells[1].
