The transition to electric vehicles motivated by global carbon neutrality targets has intensified the demand for lithium-ion batteries (LIBs) with high energy density. While innovation of cathode/anode active materials reached a plateau, development thick electrodes emerged as critical breakthrough achieving high-energy-density LIBs. However, conventional wet coating process intrinsic limitations, such binder migration during solvent drying process, which becomes increasingly problematic electrodes. To address these challenges, dry processes have been actively explored in three main forms: electrostatic spraying, hot pressing thermoplastic polymers, and roll-to-roll utilizing polytetrafluoroethylene binder. This review highlights scalable industrially viable approach, introducing its underlying mechanisms, latest developments, applications all-solid-state lithium-sulfur batteries. By combining technical advancements manufacturing scalability, demonstrates significant potential enable next-generation battery systems.

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. Based on vital design guidelines are provided for developing S‐based crucial realizing cost‐effective eco‐friendly battery production.

Abstract Sulfide electrolytes are considered the most promising technique for all‐solid‐state lithium–sulfur batteries (ASLSBs) due to relatively high ionic conductivity and superior chemical compatibility with composite sulfur cathodes. However, cathodes based on sulfide feature large volume expansion, unstable interfacial contact, inherent insulating nature, which impedes practical application of ASLSBs. Therefore, a systematic design cathode side ASLSBs is crucial ensuring well‐contacted, electrochemically stable cathode–electrolyte interface, an effective ion‐electron transfer network. Here, comprehensive discussion latest strategies will be delivered, highlighting their effectiveness in improving performances First, major challenges including slow oxidation kinetics significant expansion dissected. Then, focus shifted degradation processes at interface between electrolyte. Subsequently, improvement stability by structural modulation elaborated. Finally, progress, we present new perspective constructing efficient transport network cathode‐electrolyte offers insights directions achieving future.

Abstract Lithium iron phosphate (LiFePO 4 ) batteries are increasingly adopted in grid‐scale energy storage due to their superior performance and cost metrics. However, as the desired power further densified, lifespan of LiFePO is significantly limited, mainly because lithium plating severely occurs on graphite anode. Here, first characteristics both energy‐type power‐type electrodes single‐layer design deciphered. Based these findings, a suitable two‐layer with top layer one bottom layer, disclosed. Such configuration effectively inhibits throughout electrode, drastically increasing an energy‐ power‐densified battery. The assembled pouch cell density 161.5 Wh kg −1 , delivers capacity retention rate 90.8% after 2000 cycles at 2 C. This work provides valuable insights into failure mechanism electrodes, but also innovative strategies electrode engineering for extending batteries’ horizon.
