  "textContent": "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.",
