Lithium‐metal batteries are of particular interest for next‐generation electrical energy storage because their high density on both volumetric and gravimetric bases. Effective strategies to stabilize the Li‐metal anode prerequisite progress these exceptional technologies, such as Li–S Li–O 2 batteries. Various challenges, uneven Li electrodeposition, volume expansion, dendrite‐induced short‐circuit have hindered practical application rechargeable Herein, a one‐step facile cost‐effective...

Lithium–sulfur (Li–S) battery is one of the most promising alternatives for current state‐of‐the‐art lithium‐ion batteries due to its high theoretical energy density and low production cost from use sulfur. However, commercialization Li–S has been so far limited cyclability retention active sulfur materials. Using co‐electrospinning physical vapor deposition procedures, we created a class chloride–carbon nanofiber composites, studied their effectiveness on polysulfides sequestration. By...

A versatile strategy for a facile approach to chemical graft MOFs onto polypyrrole nanotubes (PPyNTs@MOFs) is designed and fabricated rationally by means of 1,4-dibromobutane linkage. Various arranged randomly close-packed on PPyNTs, including Co2+, Cu2+, Zn2+, Mn2+, Fe3+, Al3+, Ti4+, Cr4+, Zr4+ V4+, have been synthesized successfully. The as-prepared PPyNT@UIO-66 hybrids, used as cathode carrier, exhibit excellent cyclic stability in Li-S batteries via strong physical adsorption/affinity...
Abstract The development of the nonaqueous Li–O 2 battery, a promising candidate for high‐gravimetric‐energy‐storage techniques, is seriously restrained by high charge overpotential during electrochemical decomposition insulating Li O . Benefiting from photovoltage, photo‐assisted charging revealed as feasible method to reduce potential. However, long period illumination will inevitably aggravate degradation electrolyte.

Abstract The practical applications of lithium–sulfur (Li–S) batteries are seriously limited by the undesirable polysulfide shuttling and lithium dendrite growth. Herein, a multifunctional membrane is designed prepared coating lithiated Nafion (Li@Nafion) layer an Al 2 O 3 on two sides routine polymer (polypropylene/polyethylene/polypropylene, PEP). Li@Nafion faced to sulfur cathode builds “polysulfide‐phobic” surface restrain shuttle effect via Coulomb repulsion, while with uniform porous...
Optimization of solid electrolytes (SEs) is great significance for lithium-based state batteries (SSBs). However, insufficient Li ion transport, deficient interfacial compatibility and formation lithium dendrites lead to poor cycling performance. Based on Li+ conductive metal-organic frameworks (LCMOFs), herein a multiscale optimization strategy put forward facilitate transport within the MOFs (molecular scale), between MOFs' boundaries (nanoscale) across SE/electrode interface (microscale)...
