Abstract High-temperature sodium–sulfur batteries operating at 300–350 °C have been commercially applied for large-scale energy storage and conversion. However, the safety concerns greatly inhibit their widespread adoption. Herein, we report a room-temperature battery with high electrochemical performances enhanced by employing “cocktail optimized” electrolyte system, containing propylene carbonate fluoroethylene as co-solvents, highly concentrated sodium salt, indium triiodide an additive....
Abstract Ambient‐temperature sodium–sulfur (Na–S) batteries are considered a promising energy storage system due to their high theoretical density and low costs. However, great challenges remain in achieving rechargeable capacity long cycle life. Herein we report stable quasi‐solid‐state Na‐S battery enabled by poly(S‐pentaerythritol tetraacrylate (PETEA))‐based cathode (PETEA‐tris[2‐(acryloyloxy)ethyl] isocyanurate (THEICTA))‐based gel polymer electrolyte. The polymeric sulfur electrode...
Abstract Rechargeable alkali metal (i.e., lithium, sodium, potassium)‐based batteries are considered as vital energy storage technologies in modern society. However, the traditional liquid electrolytes applied metal‐based mainly consist of thermally unstable salts and highly flammable organic solvents, which trigger numerous accidents related to fire, explosion, leakage toxic chemicals. Therefore, exploring non‐flammable is paramount importance for achieving safe batteries. Although...

Herein, we discover that certain protein could efficiently prevent eliminate the wispy dendrites, leading to long cycle life high Coulombic efficiency anodes. We contend molecules function as a “self-defense” agent, mitigating embryos, thus mimicking natural, pathological immunization mechanisms. When added into electrolyte, are...
The low Coulombic efficiency and serious safety issues resulting from uncontrollable dendrite growth have severely impeded the practical applications of lithium (Li) metal anodes. Herein we report a stable quasi-solid-state Li battery by employing hierarchical multifunctional polymer electrolyte (HMPE). This hybrid was fabricated via in situ copolymerizing 1-[3-(methacryloyloxy)propylsulfonyl]-1-(trifluoromethanesulfonyl)imide (LiMTFSI) pentaerythritol tetraacrylate (PETEA) monomers...
