<p>An electrochemical cell (1) comprises an anode (2), a solid cathode (3) and an electrolyte (4). The electrolyte comprises an electrochemically reactive conductive salt, an organic liquid phase comprising one or more organic compounds; and less than 0.25M of an ionically charged additive, distinct from the electrochemically reactive conductive salt. The additive comprises a conductive salt which in use is not electrochemically reactive and which has a nitrogen containing cation in a sufficient quantity that conductivity is improved and percentage material utilisation of the cathode is improved at increased discharge rates as compared with a cell using an electrolyte which does not contain the additive. An improvement of approximately 10 % in conductivity is achieved for a cell according to the invention using an electrolyte (c) with an additive.</p> |
