Abstract Lithium-sulfur batteries (LSBs) have garnered significant attention as a promising next-generation rechargeable battery, offering superior energy density and cost-effectiveness. However, the commercialization of LSBs faces several challenges, including ionic/electronic insulating nature active materials, lithium polysulfide (LiPS) shuttle effect, volume expansion/contraction cathode, issues with Li metal anode. Despite numerous efforts to address these previous studies predominantly been conducted under mild conditions such high electrolyte-to-sulfur (E/S) ratio, low sulfur loading, excess metal, which cover related for realizing high-energy–density LSBs, practical E/S limited are essential. Under conditions, increased current on higher LiPS concentration exacerbate anode dendrite growth, dead Li, reactivity electrolyte, LiPSs. These problems lead rapid failure significantly impacting electrochemical performance LSBs. Consequently, protecting is crucial This paper introduces challenges associated in reviews research focused each battery component: anode, separator/interlayer.

The increasing use of low-cost lithium iron phosphate cathodes in low-end electric vehicles has sparked interest Prussian blue analogues (PBAs) for lithium-ion batteries. A major challenge with hexacyanoferrate (FeHCFe), particularly systems, is its slow kinetics organic electrolytes and valence state inactivation aqueous ones. We have addressed these issues by developing a polymeric cathode electrolyte interphase (CEI) layer through ring-opening reaction ethylene carbonate triggered OH– radicals from structural water. This facile approach considerably mitigates the sluggish electrochemical typically observed electrolytes. As result, FeHCFe achieved specific capacity 125 mAh g–1 stable lifetime over 500 cycles, thanks to effective activation Fe low-spin states integrity CEI layers. These advancements shed light on potential PBAs be viable, durable, efficient materials commercial use.
