摘要： Disclosed is a method for forming lithium hexafluorophosphate by reacting together phosphorus trichloride, chlorine and lithium chloride in a nonaqueous organic solvent and then making the reaction product formed in the solvent react with hydrogen fluoride. This method is characterized by that a lithium hexafluorophosphate concentrated liquid is obtained by conducting a filtration after making the reaction product formed in the solvent react with hydrogen fluoride and then subjecting the filtrate to a concentration by degassing. By this method, it is possible to easily produce a high-purity, lithium hexafluorophosphate concentrated liquid at a low cost.

摘要： Disclosed is a method for producing a lithium ion battery electrolyte solution containing lithium hexafluorophosphate as an electrolyte and a lithium ion battery using the electrolyte solution. The electrolyte solution is produced by reacting lithium chloride with phosphorus trichloride and chlorine in a non-aqueous organic solvent, reacting a reaction product generated in the solvent with hydrogen fluoride, reacting unreacted remaining hydrogen fluoride with lithium chloride, and then, separating the resulting reaction solution by filtration into a filtrate and a solid residue. The filtrate is obtained as the lithium ion battery electrolyte solution. The solid product is further reacted with phosphorous trichloride and chlorine in a non-aqueous organic solvent. The reaction product generated in the solvent is reacted with hydrogen fluoride, followed by reacting unreacted remaining hydrogen fluoride with lithium chloride. It is possible to accomplish reduction in production cost with the reuse of the reaction residue as production raw material.

摘要： In a manufacturing process of a transistor including an oxide semiconductor film, oxygen doping treatment is performed on the oxide semiconductor film, and then heat treatment is performed on the oxide semiconductor film and an aluminum oxide film provided over the oxide semiconductor film. Consequently, an oxide semiconductor film which includes a region containing more oxygen than a stoichiometric composition is formed. The transistor formed using the oxide semiconductor film can have high reliability because the amount of change in the threshold voltage of the transistor by a bias-temperature stress test (BT test) is reduced.
