Abstract
Some embodiments include an electrolyte composition for a battery using sodium ions as electrochemical vector, to the use of such an electrolyte composition as non-aqueous liquid electrolyte in a sodium-ion battery and to a sodium-ion battery comprising such a non-aqueous liquid electrolyte. In some embodiments, the amount of (oxalato)borate ranges from 0.05 to 10 wt. %, relative to the total weight of the electrolyte composition.
