摘要： Provided is a transparent conductive piezoelectric laminate film that achieves high transparency and low resistance. The present invention relates to a transparent conductive piezoelectric laminate film including a piezoelectric film, and a conductor layer layered on at least one surface of the piezoelectric film. The transparent conductive piezoelectric laminate film has a diffraction peak in each of a range of 21° ± 2° and a range of 31° ± 2° in X-ray diffraction measurement, and a haze value of 2.0% or less.

摘要： The object of the present invention is to provide a carbonaceous material which is obtainable from plant-derived char and has a decreased specific surface area. Further, the object of the present invention is to provide a non-aqueous electrolyte secondary battery having excellent dedoping capacity (discharge capacity), non-dedoping capacity (irreversible capacity), and charge-discharge efficiency.
The object can be solved by a carbonaceous material for non-aqueous electrolyte secondary batteries characterized in that the carbonaceous material is obtained by heat-treating plant-derived char which is demineralized in gas-phase, and carbon precursor (i.e. non-graphitizable carbon precursor, graphitizable carbon, or mixture thereof) or volatile organic compound under a non-oxidizing gas atmosphere; and a specific surface area determined by a BET method is 10 m 2 /g or less. Further, the object can be solved by a carbonaceous material for non-aqueous electrolyte secondary batteries characterized in that the carbonaceous material is obtained by heating plant-derived char, and hydrocarbon compound having 1 to 20 carbon atoms; and a specific surface area determined by a BET method is 15 m 2 /g or less.
