Abstract
A polyimide binder from which a high-capacity power storage device, which has a small irreversible capacity and a high initial charge/discharge efficiency and is lightweight, can be obtained. The polyimide binder precursor composition is a polyimide binder precursor composition for a power storage device electrode, and includes a reaction product of a tetracarboxylic acid component and a diamine component, and a solvent. The polyimide binder obtained from the polyimide binder precursor composition has an irreversible capacity of 1200 mAh/g or less.
