Conjugated microporous polymers (CMPs), as an emerging class of organics, have generated keen interest due to their excellent structural stability and stronger designability. Herein, redox donor–acceptor conjugated (TAPB-AQ PBAPD-AQ) were prepared by utilizing anthraquinone anilines linkers via C–N linkages used anodes build high-performance LIBs. Compared with TAPB-AQ, PBAPD-AQ has more electroactive groups, a narrower band gap, higher thermal decomposition temperatures (5% mass loss was up 384 °C). Benefiting from the insolubility in electrolyte richer pore structure, shows high capability (219.8 mA h g–1 at 0.5 A g–1) ultrastable cycling performance (96.1% retention after 1200 cycles g–1). Moreover, lithium storage mechanism anode electrode material is explored through ex situ XPS DFT computations.

Abstract Carbon‐based interlayer as the secondary current collector is a typical approach for suppressing polysulfide shuttle effect in lithium‐sulfur batteries (LSBs). The effective operating lifespan determined by balance between local concentration and bearing capacity of interlayers. However, microscopic diffusion polysulfides within interlayers under multiple force fields remains unclear, particularly catalyst on multi‐scale behavior. Herein, first identification reported with coupling longitudinal osmotic transverse radioactive through revisiting Mn‐based catalysts (Mn‐X, X = N, O, or P). In addition to electric field forces during charging discharging, free sustain tension, leading radiation This adaptive adjustment optimizes distribution, mitigating risk deactivation caused excessive concentration. extent lateral positively correlated physicochemical adsorption interlayer. Specifically, stronger static demonstrates broader range. work re‐evaluates behavior interlayers, further guiding design high performance collector.

Abstract With the booming development of Li‐ion batteries (LIBs), recycling and reusing spent graphite (SG) from LIBs is becoming increasingly crucial. Meanwhile, developing low‐cost efficient carbon hosts for lithium–sulfur (Li–S) has gained widespread attention in past decade. Nevertheless, processing materials as sulfur often energy‐consuming complex. Herein, a simple environmental‐friendly strategy proposed to reuse SG prepare graphene/sulfur composite cathode Li–S batteries. Due expanded layer spacing defects SG, molecules can strip it into graphene‐type host via ball milling. By optimizing S/SG ratio milling time, as‐prepared with 70 wt.% content exhibits high capacity 1000 mAh g −1 . loading 4.68 mg cm −2 , maintain 526 after 400 cycles. This work provides novel waste‐to‐wealth perspective
