摘要： PROBLEM TO BE SOLVED: To provide electrolyte particles superior in formability and a method of manufacturing the electrolyte particles.
SOLUTION: The electrolyte particles are prepared by mechanically mixing electrolytic raw material crystalline particles having lithium ion conductivity with a lithium salt, thereby causing distortion in the raw material crystalline particles. By mixing the raw material crystalline particles with the lithium salt, a distortion can be generated in the crystalline structure of the raw material crystalline particles. The electrolyte particles with distortion in the crystalline structure are easy to be deformed, and can be made into a formed body without applying heat. Also, this formed body is superior in lithium ion conductivity since the contact area between each of electrolytic particles constituting the formed body is large.

摘要： PROBLEM TO BE SOLVED: To provide a lithium battery having high capacity, flexibility, and high productivity, and to provide the manufacturing method of it.
SOLUTION: The lithium battery 3 has on a substrate 10 a positive electrode layer 33, a negative electrode layer 34 containing an active material comprising a Li-containing material, a solid electrolyte layer 35 interposed between both electrode layers 33, 34, and a current collector layer 31. The substrate 10 is made of insulating resin which has a melting point of 170°C or higher and does not react with lithium. Since the substrate 10 is made of resin and the layers 31-35 are formed by a gas phase deposition method or a coating method, the battery 3 has flexibility. Since the positive electrode layer 33 is made in a thick film and the negative electrode layer 34 contains lithium, the battery 3 has high capacity. Since the positive electrode layer 33 having the thick film is formed by coating method, it can be manufactured in a short time, and the battery 3 has high productivity.
