Abstract: A film and a flexible metal-clad laminate obtained with the film. The laminate is improved in post-moisture absorption solderability. The film comprises a heat-resistant polyimide film and, disposed on at least one side thereof, an adhesive layer containing a thermoplastic polyimide. It is characterized in that the thermoplastic polyimide contained in the adhesive layer has crystallinity and that the film, when analyzed with a differential scanning calorimeter, has an endothermic peak attributable to the melting of the crystalline thermoplastic polyimide, the absolute value of the area of the peak being 4.0 mJ/mg or larger. The flexible metal-clad laminate is characterized by comprising the film and a metal layer disposed thereon.

Abstract: A method for producing a positive electrode active material is provided. The method can prevent a gas generation due to an oxidative degradation of a non-aqueous electrolyte in a lithium-ion secondary battery using a positive electrode active material which operates at a high potential. A method for producing a coated positive electrode active material for a lithium-ion secondary battery includes coating a surface of a positive electrode active material with an oxide-based solid electrolyte by a mechanical coating method and then conducting heat treatment at 300° C. or higher, and the positive electrode active material has an average potential of extraction and insertion of lithium of 4.5V or more and 5.0V or less based on Li+/Li.
