发明名称 Thin film lithium conducting powder material deposition from flux
摘要 The present invention is directed to battery technologies and processing techniques thereof. In various embodiments, ceramic electrolyte powder material (or component thereof) is mixed with two or more flux to form a fluxed powder material. The fluxed powder material is shaped and heated again at a temperature less than 1100° C. to form a dense lithium conducting material. There are other variations and embodiments as well.
