<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a nonaqueous electrolyte battery, capable of restraining generation of malfunction on a solid electrolyte layer at the time of film deposition of the solid electrolyte layer by a gas phase method. <P>SOLUTION: In the method for manufacturing a nonaqueous electrolyte battery, a positive electrode layer 1 forming a positive electrode active material layer 12 including lithium composite oxide to be a positive electrode active material is prepared on a metal substrate as a positive electrode collector 11. Then, when a solid electrolyte layer (SE layer 3) is formed on the positive electrode active material layer 12 of the positive electrode layer 1 by the gas phase method, temperature of the positive electrode layer 1 is controlled at 0-90°C. Tensile stress acting on a film of a solid electrolyte membrane deposited on the positive electrode layer 1 can be lessened by controlling the temperature of the positive electrode layer 1, and that, crystallization of the solid electrolyte can also be restrained. Consequently, generation of malfunction occurring on the SE layer 3 film deposited on the positive electrode layer 1 can be restrained. <P>COPYRIGHT: (C)2011,JPO&INPIT |
