Abstract

A porous polyimide film is obtained from a poly(amic acid) solution containing (a) a poly(amic acid), (b) an organic polar solvent that is a good solvent for the poly(amic acid), and (c) a hydrophobic solvent that is a poor solvent for the poly(amic acid). The poly(amic acid) is obtained by polymerizing an aromatic tetracarboxylic dianhydride containing at least pyromellitic dianhydride and an aromatic diamine containing at least 4,4′-diaminodiphenyl ether. The hydrophobic solvent dissolves in the organic polar solvent, evaporates less readily than the organic polar solvent at the same temperature and pressure, and has a log P in the range of 4.00 or more and 6.00 or less. A method of producing a porous polyimide film includes obtaining a porous polyimide film by drying and then baking a poly(amic acid) solution.

The invention addresses the problem of providing a polyimide precursor, a polyimide precursor solution, and a mixture slurry, each capable of more firmly binding active material particles to a current collecting body. The polyimide precursor solution according to the invention contains a tetracarboxylic acid ester compound, a diamine compound having an anionic group, and a solvent. The solvent dissolves the tetracarboxylic acid ester compound and the diamine compound. As the tetracarboxylic acid ester compound, a 3,3',4,4'-benzophenonetetracarboxylic acid diester is particularly preferred.

Abstract

A folding device having a simplified structure, capable of being easily maintained and repaired, and inexpensive. The folding device has a placement member (31), a rotation mechanism (33), and plate-like members (32). The placement member (31) is a plate-like member, on a first surface of which an object to be folded is placed such that a portion of the object hangs from the surface. The rotation mechanism (33) rotates the first surface of the placement member (31) about an axis included in the first surface. The plate-like members (32) can position the portion of the object to a place near the placement member (31) by rotation of the placement member (31) caused by the rotation mechanism (33), and then the plate-like members (32) moves the portion of the object to the placement member (31) side while holding the portion.
