Abstract
An ion conductive film and a precursor thereof which comprises a film composed of an aromatic polyamide, electrolyte and solvent in which a content of the aromatic polyamide is between 20 and 70% by weight. The film is easy to handle due to heat resistance, resistance to chemicals and mechanical properties. Little deterioration of the properties, or change in the structure of the film is caused by aging and exposure to heat. The film is especially suited for various electrochemical usages including battery separator.
