A film-forming composition that attains an improvement in the solubility of a hole-injecting/transporting material and/or an electron-accepting compound and has a drying rate appropriate for stable formation of a uniform coating film, being suitable for the formation of a hole-injecting/transporting layer. This composition comprises a hole-injecting/transporting material and/or an electron-accepting compound and a liquid in which the hole-injecting/transporting material and/or the electron-accepting compound are dissolved. This liquid mainly contains a solvent whose molecule has an aromatic ring and/or an aliphatic ring and an oxygen atom and which has either a boiling point of at least 200°C or a vapor pressure of 1 torr or lower at 25°C.
The present invention relates to a battery comprising at least one electrochemical cell comprising a first electrode, a second electrode, a first electroactive material, a second electroactive material and an electrolyte which is in contact with both electrodes, wherein at least one of the first electroactive material and the second electroactive material comprises a radialene compound; to an electroactive material as well as to a compound therefore.
