The exploration of new application forms of covalent organic frameworks (COFs) in LiÀSb atteries that can overcome drawbacks like lowconductivity or high loading when typically applied as sulfur host materials (mostly % 20 to % 40 wt %l oading in cathode) is desirable to maximizet heir low-density advantage to obtain lightweight, portable,orhighenergy-density devices.H ere,w ee stablish that COFs could have implications as microadditives of binders ( % 1wt% in cathode), and as eries of anthraquinone-COF based hollow tubes have been prepared as model microadditives.T he microadditives can strengthen the basic properties of the binder and spontaneously immobilize and catalytically convert lithium polysulfides,a sp roved by density functional calculations,thus showing almost doubly enhanced reversible capacity compared with that of the bare electrode.
