摘 要：Alkali-ion batteries,including potassium-ion batter-ies,lithium-ion batteries,and sodium-ion batteries are important energy storage devices;however,with the cation size increased,there exists a great challenge for an inorganic electrode material to accommodate the different properties of the ***,as a proof-of-concept experiment,an imine-rich poly(o-phenylenediamine)(PoPD)is syn-thesized through a rational controllable *** to the abundance of active sites and ladder-conjugated structure,PoPD in the optimized oxida-tion state endows alkali-ion batteries with a stable cyclability at high *** highly reversible redox performance of PoPD with alkali-ions is verified by theoretical calculations and demonstrat-ed as a trifunctional electrode material(537 and 307 mAh·g^(−1) for Li and Na storage capacity after 300 cycles,respectively),especially for successful application in potassium storage(450 mAh·g^(−1) after 205 cycles),and provides compelling evidence for the wide application of organic electrode materials.
