Antimony trioxide is a prominent additive for halogen -containing flame retardants. It improves the rigidity of lead-alloy plates in leadacid batteries. This work supplies a new perspective of HBEB sites in maximizing the desirable K+ storage. The largest applications for metallic antimony are in alloys with lead and tin, which have improved properties for solders, bullets, and plain bearings. Such displays impressively reversible capacity of 819 mAh gā1 at 0.05 A gā1, prominent cycle ability with a 73% capacity conservation after 500 loops at 2 A gā1, and extraordinary capacity retentions of 66%, 84% at -40 and 70ā, respectively, for K+ ion storage. Despite its potential toxicity, antimony is known to have been used for medicinal and cosmetic purposes in ancient times. Comprehensive experimental evaluation and theoretical calculation corroborate that the flexible-robust with stable sulphide radicals is enabled with prominent self-healing ability, high K+ ion transfer number of 0.84, and wider temperature adaptability, benefiting from additional binding sites and tailored spin state via smart hydrogen bonds exchange. Herein, Bi0.67Sb1.33S3 nanospheres closely embedded into the in-situ formed poly (3, 4-ethylenedioxythiophene) intertwined polythioctic acid supramolecule polymer were elaborately conceptualized, whereas the interface environment was finely regulated via hydrogen bonds exchangeable binding (HBEB) sites. The largest use of antimony metal is as an alloy with lead, tin and lead antimony plates in lead acid batteries. However, the sluggish kinetics, and poor interface compatibility especially at harsh conditions severely confine its practical application. Antimony compounds are used to make fire retardants, paints, ceramic enamels, glass and pottery. Antimony (Sb)-based anode is one of attracting candidates in potassium-ion batteries (PIBs) due to their super capacities and rational potassium inserting voltages.
