摘要： An object of the present invention is to provide a novel sulfur-based positive-electrode active material which can largely improve cyclability of a lithium-ion secondary battery, a positive electrode comprising the positive-electrode active material and a lithium-ion secondary battery comprising the positive electrode. The sulfur-based positive-electrode active material is one comprising: a carbon skeleton derived from a polymer composed of a monomer unit having at least one hetero atom-containing moiety, the hetero atom being O, and sulfur incorporated into the carbon skeleton as the carbon skeleton is formed from the polymer by heat treatment.

摘要： 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. Examples of the "diamine compound having an anionic group" include 3,4-diaminobenzoic acid, 3,5-diaminobenzoic acid, and m-phenylenediamine-4-sulfonic acid. Further, the mixture slurry according to the invention contains active material particles in the polyimide precursor solution.

摘要： Disclosed is a nickel positive electrode for a fiber battery having a long life duration, and also being enabling a high output and high capacity to be attained. For this purpose, the nickel positive electrode for a fiber battery is obtained by coating a carbon fiber with nickel, then causing a cathodic polarization in a nickel nitrate bath using the nickel-coated carbon fiber as a cathode, and then immersing the precipitate, which was deposited on the surface of the carbon fiber by the cathodic polarization, in an aqueous caustic alkali solution.
