Polyperylenediimide (PDI) is always subject to its modest conductivities, limited reversible active sites and inferior stability for potassium storage. To address these issues, herein, we firstly propose an organic–inorganic hybrid (PDI@Fe‐Sn@N‐Ti3C2Tx), where Fe/Sn single atoms are bound to the N‐d...
