Abstract
Use of an electrolyte for an electrochemical cell and a method for manufacturing an electrochemical cell comprising such an electrolyte. The electrolyte comprises at least one conductive salt comprising lithium ions, at least one solvent and at least one wetting agent. The electrochemical cell comprises at least one anode, at least one cathode and at least one separator arranged between the at least one anode and the at least one cathode. The electrolyte may be filled between the at least one anode and the at least one cathode.
Claims5
A method for manufacturing a large format electrochemical cell, the method comprising the steps of:
- providing at least one anode, at least one cathode and at least one separator between the at least one anode and the at least one cathode, wherein the at least one cathode, the at least one anode and the at least one separator have at least one dimension of about 100 mm or more;
- and
- filling an electrolyte between the anode and the cathode in a single filling step, wherein the electrolyte comprises at least one wetting agent, wherein filling the electrolyte between the anode and the cathode is performed under vacuum conditions at a pressure of about 10 to 500 mbar abs and wherein the at least one wetting agent comprises a fluoropolymer or a non-ionic surfactant.
