Abstract
A sodium electrochemical cell that supports a current density at the negative electrode of at least 500 μA/cm, the electrochemical cell comprising (i) a negative electrode and (ii) a sodium-ion ionic liquid electrolyte having a sodium-ion concentration that is no less than 75% of its saturation limit in the electrolyte, wherein the negative electrode has a solid-electrolyte interphase (SEI) layer formed as a result of the electrochemical cell having undergone a polarisation cycle.
