Abstract: Provided is an electrolyte for use in a secondary zinc halide electrochemical cell comprising: from about 20 wt.% to about 70 wt.% of a zinc halide of formula ZnY2 or any combination of zinc halides of formula ZnY2, wherein Y is a halide selected from fluoride, chloride, bromide, iodide, or any combination thereof; from about 10 wt.% to about 79 wt.% of H2O; and from about 0.5 wt.% to about 20 wt.% of one or more zinc additives. The one or more zinc additives comprises a first zinc additive, wherein, the first zinc additive is a salt that is not a zinc halide and comprises an anion with a van der Waals volume of greater than about 65 Â3. Also provided, is a secondary zinc halide battery comprising at least one electrochemical cell comprising at least one bipolar electrode and the zinc halide electrolyte. Also provided is a secondary zinc halide battery comprising a zinc metal reservoir.

Abstract: The present invention is directed towards a process for making an electrode wherein the process comprises the following steps (a) providing a particulate lithiated transition metal oxide according to the formula Li1+xTM1-xO2 wherein x is in the range of from zero to 0.1 and TM contains nickel and at least one of Co, Mn and Al, (b) mixing the lithiated transition metal oxide from step (a) with carbon in electrically conductive form, (c) exposing the mixture obtained in step (b) to a pressure in the range of from 100 to 500 MPa over a period of time of from one second to one minute, thereby causing cracks in at least some of the particles of the electrode active material, (d) mixing the mixture from step (c) with a binder polymer and, optionally, with further carbon in electrically conductive form and with a solvent, (e) applying the mixture from step (d) to a metal foil.
