Method for synthesizing thin film electrodes
View Patent ↗A method for making a thin-film electrode, either an anode or a cathode, by preparing a precursor solution using an alkoxide reactant, depositing multiple thin film layers with each layer approximately 500–1000 Å in thickness, and heating the layers to above 600° C. to achieve a material with electrochemical properties suitable for use in a thin film battery. The preparation of the anode precursor solution uses Sn(OCH 2 C(CH 3 ) 3 ) 2 dissolved in a solvent in the presence of HO 2 CCH 3 and the cathode precursor solution is formed by dissolving a mixture of (Li(OCH 2 C(CH 3 ) 3 )) 8 and Co(O 2 CCH 3 ).H 2 O in at least one polar solvent.
1. A method for making an electrode, comprising synthesizing a precursor solution, said precursor solution selected from an anode precursor solution and a cathode precursor solution, wherein said anode precursor solution is formed by dissolving Sn(OCH 2 C(CH 3 ) 3 ) 2 in a solvent in the presence of HO 2 CCH 3 and wherein said cathode precursor solution is formed by dissolving a mixture of (Li(OCH 2 C(CH 3 ) 3 )) 8 and Co(O 2 CCH 3 ).H 2 O in at least one polar solvent, depositing at least one thin film layer using said precursor solution, and heating said at least one thin film layer to a temperature greater than approximately 650° C.
2. The method of claim 1 wherein said solvent is selected from toluene, hexane, tetrahydrofuran, and pyridine.
3. The method of claim 1 wherein said at least polar solvent is selected from pyridine, tetrahydrofuran, and toluene.
4. The method of claim 1 wherein said at least one thin film layer has a thickness between approximately 500 Å and 1000 Å.
5. The method of claim 1 wherein said step of depositing at least one thin film layer is performed using a spin-coat deposition technique.
6. The method of claim 1 wherein said step of depositing at least one thin film is performed in the presence of water vapor.
