Abstract

The present invention relates to a sodium ion cell comprising:- a positive electrode comprising a sodium Prussian blue analogue according to formula AaMb[M'c(CN)6]d,wherein A is sodium, 1 < a ≤ 2, M and M' are individually one or more transition metals, 0 < b < 2, 1 ≤ c < 2, and 1 ≤ d < 2;- a negative electrode comprising a carbon-based sodium inserting material; - a separator, and- an electrolyte comprising a sodium salt, an organic carbonate-based solvent comprising at most 50 wt.% of cyclic organic carbonate, a first additive, and a second additive comprising an organic sulfate,wherein said first additive is a cyclic carbonate according to formula (I) or formula (II) and different from said cyclic organic carbonate in said organic carbonate-based solvent.
