“…Until now, all the solid-state batteries in the halide SSEs system are still focused on traditional oxide cathodes. [17,19,25,31,32] While there have been predictions that halide SSEs can be used to explore the reversible storage of Li + into new compounds other than oxide cathodes.…”

Solid‐state Li–S and Li–Se batteries are promising devices that can address the safety and electrochemical stability issues that arise from liquid‐based systems. However, solid‐state Li–Se/S batteries usually present poor cycling stability due to the high resistance interfaces and decomposition of solid electrolytes caused by their narrow electrochemical stability windows. Here, an integrated solid‐state Li–Se battery based on a halide Li3HoCl6 solid electrolyte with high ionic conductivity is presented. The intrinsic wide electrochemical stability window of the Li3HoCl6 and its stability toward Se and the lithiated species effectively inhibit degeneration of the electrolyte and the Se cathode by suppressing side reactions. The inherent thermodynamic mechanism of the lithiation/delithiation process of the Se cathode in solid is also revealed and confirmed by theoretical calculations. The battery achieves a reversible capacity of 402 mAh g−1 after 750 cycles. The electrochemical performance, thermodynamic lithiation/delithiation mechanism, and stability of metal‐halide‐based Li–Se batteries confer theoretical study and practical applicability that extends to other energy‐storage systems.

“…The explosive demands for mobile electronic devices have greatly invoked the development of high‐energy density lithium batteries. [ 1 ] As a typical representative, lithium–sulfur batteries (LSBs) have been widely concerned owing to their high theoretical energy density (2600 Wh kg −1 ) and low cost. [ 2 ] However, the large‐scale promotion of LSBs is still challenged by some issues.…”

Lithium–sulfur batteries (LSBs) have attracted extensive attention owing to their high energy density and abundant sulfur resources. However, LSBs are still restricted by the unsatisfactory electrochemical performance resulting from the shuttle effect of lithium polysulfide (LiPSs), and the potential fire hazard caused by inflammable ether electrolytes and polyolefin separators. Herein, a facile immobilization strategy for hexachlorocyclotriphosphazene (HCCP) is creatively applied to address the above issues simultaneously. Insoluble HCCP cross‐linked microspheres (H‐CMP) are firstly obtained at ambient temperature using tannic acid (TA) as a cross‐linking agent and then a multifunctional separator coating is constructed based on H‐CMP. The released phosphorus‐related radicals from H‐CMP in wide temperatures effectively prevent the combustion of electrolytes and separators, and hence improve the fire safety of the Li–S pouch cell. Furthermore, H‐CMP availably chemisorbs LiPSs to interdict the shuttle effect, thereby dramatically improving the electrochemical performance of LSBs. The effectiveness of this strategy is also verified in high sulfur loading (6.38 mg cm‐2), high temperature (50 °C), and Li–S pouch cells. More importantly, H‐CMP exhibits sufficient stability for Li metal and suppression of Li dendrites. This facile immobilization strategy for multifunctional phosphazenes provides a competitive option for the large‐scale fabrication of high‐safety and high‐performance LSBs.
