Abstract
Official abstract text for this publication.
A Li or Li-ion or Na or Na-ion battery cell is provided that comprises anode and cathode electrodes, a separator, and a solid electrolyte. The separator electrically separates the anode and the cathode. The solid electrolyte ionically couples the anode and the cathode. The solid electrolyte also comprises a melt-infiltration solid electrolyte composition that is disposed at least partially in at least one of the electrodes or in the separator.
First claim
Opening claim text (preview).
1 . A method of producing a Li or Li-ion or Na or Na-ion battery cell, comprising: melting at least part of a solid electrolyte composition to produce a molten solid electrolyte; infiltrating the molten solid electrolyte into at least one of an anode electrode, a cathode electrode or a separator electrically separating the anode electrode and the cathode electrode; and cooling the infiltrated molten solid electrolyte composition so as to produce a melt-infiltration solid electrolyte composition disposed at least partially in the at least one of the anode electrode, the cathode or the separator, the melt-infiltration solid electrolyte composition being part of a solid electrolyte ionically coupling the anode electrode and the cathode electrode. 2 . The method of claim 1 , further comprising: depositing, before the melting, the solid electrolyte composition on the at least one of the anode electrode, the cathode electrode or the separator, wherein the melting occurs in response to heat being applied to an assembly comprising a combination of (i) the deposited solid electrolyte composition and (ii) the at least one of the anode electrode, the cathode electrode or the separator, and wherein the infiltrating occurs as a result of the melting and the depositing. 3 . The method of claim 1 , wherein the melting occurs in response to heat being applied to the solid electrolyte composition without heating an assembly comprising the at least one of the anode electrode, the cathode electrode or the separator, and wherein the infiltrating includes dipping the assembly into the molten solid electrolyte.
