Internal Electric Field‐Guided, Low‐Adsorption Ferroelectric Anode Protective Layers for Sustainable Suppression of Polysulfide Side Reactions in Lithium–Sulfur Batteries
Lithium–sulfur batteries (LSBs) offer energy densities beyond lithium‐ion batteries, yet parasitic reactions between soluble polysulfides and lithium metal cause active‐sulfur loss and porous Li, undermining cycle life. To address this problem, an anode protective layer is needed, but interactions between protectiv...
