ABSTRACT:
In any manufacturing sequence for making a lithium ion-switching device, lithium has to be introduced at some stage into the device. An electrode inside the device is filled and depleted with lithium through an ion conductor at every use cycle of the device. Prior-art methods to introduce the lithium are: direct sputtering of lithium on the electrode, or electrochemically loading the electrode in an electrochemical cell, or indirectly loading the electrode after an ion conductor has been deposited on top of the electrode and still other methods. The inventive method disclosed makes such a separate lithiation step obsolete. The lithium is introduced at the same time as the ion-conductor is put on the electrode. This can be achieved by using an oxygen super-stoichiometric compound for the electrode.
