Abstract A combination of material innovations, advanced manufacturing, battery management systems, and regulatory standards is necessary to improve the energy density safety lithium (Li) batteries. High‐energy‐density solid‐state Li‐batteries have potential revolutionize industries technologies, making them a research priority. The improved compatibility with high‐capacity electrode materials makes solid‐stateLi‐batteries polymer solid‐electrolytes an attractive option for applications where are critical. While polymer‐based hold enormous promise, there still several challenges that must be addressed, particularly regarding interface between solid‐electrolyte Lianode. There significant advancements in improving performance Li batteries, researchers continue explore new methods address these challenges. These improvements critical enabling widespread adoption invariety applications, from electrical vehicles portable electronics. Here, common its Lianode first introduced, highlighting trend solid‐state‐electrolyte toward enhancing stability, safety, Li‐batteries. This includes developing novel properties, exploring fabrication techniques, integrating electrolytes into designs optimize both density.

Aimed at the application drawbacks of lithium‐polysulfide semiflow battery involved with low utilization active material and inevitable shuttle effect, a self‐supporting porous substrate characterized by high porosity outstanding conductivity is developed in this study, which consists cotton‐derived nanofiber graphene wrapped on nanofiber. Then gelable polymer poly‐(vinylidenefluoride‐hexafluoropropylene) further integrated into for fabricating novel PS gel cathode. The as‐prepared composite matrix possesses strong adsorption/loading ability gelation as well favorable electron/ion transport pathway, not only provides effective restriction toward migration shuttle, but also actualizes rapid redox conversion localized species. Consequently, resultant cathode demonstrates reversible capacity, excellent cycle rate capability even sulfur loading up to 9.0 mg cm −2 .
