Abstract In this study, a selenium‐doped sulfurized polyacrylonitrile (Se‐SPAN) cathode fabricated by dry process with multi‐walled carbon nanotubes (MWCNT) and polytetrafluoroethylene (PTFE) binder is proposed to address issues in currently developed dry‐processed cathodes. The Se‐SPAN (D/Se‐SPAN) characterized dense, robust, uniform structure that successfully resists the internal stress evolution caused significant volume variations of under high‐loading conditions. Understanding these architectural advantages D/Se‐SPAN, unrivaled potential D/Se‐SPAN compared traditional slurry‐processed cathodes (S/Se‐SPAN) established through series in‐depth electrochemical‐mechanical investigations. As result, recorded ≈31.8 mAh cm −2 reversible areal capacities ultra‐high‐loading conditions (64.2 mg ) exhibited remarkable cycle stability.

Abstract The electrolytes for advanced lithium‐metal batteries need to simultaneously achieve high‐performances in ion‐conductivity, lithium‐ion transference number, elasticity and mechanical strength, safety etc. Gel polymer (GPEs) are promising, however, conventional GPEs find it challenging all these performances, mainly due a poor control of the liquid plasticizer inside. Here, inspired by animal skins that can perfectly overcome trade‐off between mechanics complex biofunctions via water‐encapsulation inside cellular network, is attempted design fabricate type skin‐inspired nonflammable elastic GPE (SINE‐GPE) address this challenge. To do that, an anti‐solvent induced self‐assembly (ASISA) strategy proposed porous vesicular membrane based on triblock thermoplastic polyurethane (i.e., SINE‐skeleton). Then, electrolyte encapsuled SINE‐skeleton prepare SINE‐GPE. resultant SINE‐GPE achieves not only high gel‐strength 2.0 ± 0.1 MPa, recoverable strain 90% ionic conductivity 1.2 × 10 −3 S cm −1 at RT, but also selective transport (t Li+ = 0.82). Consequently, effectively stabilize anode with smooth solid‐electrolyte‐interphase, which explained self‐massaging mechanism during lithium stripping deposition.
