Abstract
A 3D polyimide is designed as an organic cathode for Li-ion batteries. Detailed characterization and DFT simulations demonstrate that the 3D polyimide undergoes the redox of naphthalenediimide radicals and the rigidity effect of the 3D structure contributes to the stability of the radical intermediates for high-performance organic batteries.
