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.

The invention discloses a colorless and transparent polyimide resin material. 1,2,3,4-cyclohexanetetracarboxylic dianhydride is chosen as dianhydride monomer or comonomer to carry out polycondensation reaction with primary diamine, so that the polyimide resin material is prepared. Because the 1,2,3,4-cyclohexanetetracarboxylic dianhydride comonomer has a distorted molecular structure, a large free volume exists between polymer molecular chains, and thereby the formation of charge transfer complex (CTC) in and between polyimide molecules is inhibited; and meanwhile, because of the introductionof a lipid structure, the electron-stimulated transition mode in the polyimide molecular chains is changed, the absorption of the aromatic polyimide in the visible light region is remarkably weakened, and thereby the transparency of the polymer is greatly increased. The ultraviolet light transmission cutoff wavelength of a produced polyimide film is 280nm to 380nm, the light transmissivity at 450nm is 86 to 94 percent, moreover, the glass-transition temperature is 250 DEG C to 400 DEG C, and the polyimide resin material has a good application prospect in the fields of flexible substrate materials for solar cells, flexible transparent conducting film substrate materials, liquid crystal display materials and the like.
