Abstract

The disclosure relates to a method of preparing an electrode assembly for a sodium ion cell, comprising a cellulose separator. The properties of the cell may be improved by optimising the drying process of the electrode assembly by measuring and analysing the colour of the cellulose separator. In particular, there is provided a method of preparing an electrode assembly comprising a cellulose separator and a Prussian Blue Analogue as a cathode.
