Embodiment 1

[0135] Using a twin-screw kneader (manufactured by Plabor Co., Ltd.) equipped with a fan saw (segment) designed to be able to vigorously knead the material, by kneading 56% by weight of calcium carbonate (trade name: Vigot 10, manufactured by Shiraishi Calcium Co., Ltd. Manufactured, average particle diameter: 0.1 μ m), 32% by weight of polyethylene powder (HI-ZEX MILLION 340M, manufactured by Mitsui Chemicals, weight average molecular weight = 3000000, melting point = 136 ° C) and 12% by weight of polyethylene wax (HI - WAX110P, manufactured by Mitsui Chemicals, weight average molecular weight = 1000, melting point = 110°C) to produce a resin composition. The obtained resin composition was rolled at a rolling temperature of 151° C. to produce an initial film having a thickness of about 60 μm.

[0136] The initial film was uniaxially stretched at a stretching temperature of 110°C on a tenter frame at a stretching ratio of about 6.5 times to produce a porous film. Calcium carb...

[0154] (1) Para-aramid (Paraaramid) solution composition

[0155]Synthesize poly(paraphenylene terephthalamide) (poly(paraphenylene terephthalamide, hereinafter abbreviated as PPTA)) using a 5-liter separation bottle equipped with a stirring blade, a thermometer, a nitrogen delivery tube and a powder addition port. In a completely dry In the bottle, 4200 g of NMP was charged. Next, 272.65 g of calcium chloride dried at 200° C. for 2 hours was also added and heated to 100° C. When the calcium chloride was completely dissolved, the mixture was cooled to room temperature. Next, 132.91 g of calcium chloride was added g of p-phenylenediamine (hereinafter abbreviated as PPD) and completely dissolved. When the solution was maintained at 20 ± 2°C, add 243.32g of terephthalyl dichloride (terephthalyl dichloride, hereinafter abbreviated as TPC) in ten parts at intervals of about 5 minutes ). Thereafter the solution was kept at 20±2° C. for one hour and then s...

Abstract

The present invention provides a porous electrode comprising a porous film (A) with through pores and an electrically conducting material selected from the group consisting of conductor and semiconductor, the porous film (A) having an average pore size d1 of from 0.02 to 3 m and a porosity of from 40 to 90%, the electrically conducting material being filled in the through pores of the porous film (A) . A dye-sensitized solar cell and an electric double layer capacitor including the porous electrode as a constituent are also disclosed.

Description

technical field [0001] The present invention relates to a porous electrode, a composite member including the porous electrode, and a dye-sensitized solar cell and an electric double layer capacitor including the porous electrode of the composite member as components. The invention also relates to methods for producing the porous electrode and the composite element. Background technique [0002] Photoelectric conversion elements such as solar cells are expected to be a clean energy source. For example, pn-junction silicon-based solar cells have been used in practice. However, because silicon-based solar cells require high-purity raw materials and the manufacture of the cells requires high-temperature processing or vacuum processing operating at about 1000° C., reducing production costs is a major challenge. Therefore, more attention has recently been focused on wet solar cells, which do not require high-purity raw materials or high-energy processing, and which separate char...
