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 accor...

The object of the present invention is to offer a binder composition for electrodes with greater binding strength that does not inhibit the formation of a stable electrode interface (SEI) on the surface of the layer active material. The binder composition ...
