Abstract Lithium–sulfur batteries (LSBs) are considered as one of the most promising next‐generation energy‐storage devices because their high energy density. However, long‐term use LSBs is mainly limited by polysulfide shuttling and cathode structural degradation caused volume changes during charging discharging. To address these issues, a multifunctional, high‐performance aqueous binder developed modifying natural polysaccharide with multi‐walled carbon nanotubes (MWCNTs). Specifically, catechol‐conjugated chitosan (CCS) acts binder, showing strong adsorption, while MWCNTs covalently bonded to CCS enhance mechanical toughness electronic conductivity. The resulting CCS‐MWCNTs composite exhibits tensile strength 40 MPa strain at break 300%, which higher than those CCS. As for sulfur cathodes, demonstrates superior cyclic stability rate capability. At loading 2.0 mg cm⁻ 2 , it delivers an initial capacity 1016 mAh g⁻¹ 0.2 C retains 690 after 100 cycles, significantly outperforming commercial polyvinylidene difluoride (PVDF), sodium carboxymethylcellulose/styrene butadiene rubber (CMC/SBR), binders. This study potential applications binders in metal‐sulfur innovatively incorporating into biopolymer providing alternative environmentally friendly storage.

Binderless Dry Cathode Using a Nanoparticle Deposition System for Lithium-Ion Battery Applications

ACS Applied Materials & Interfaces, Год журнала: 2025, Номер unknown

Опубликована: Апрель 24, 2025

Binder-free dry cathodes are in high demand because they can significantly reduce production costs by eliminating solvent removal and recovery processes increase energy density the need for binders, which electrochemically inactive materials. To address these critical challenges, to best of our knowledge, this study is first propose introduce a nanoparticle deposition system (NPDS) producing binder-free lithium-ion batteries. The NPDS process produces films via supersonic acceleration powder, followed collision with substrate, using simple pressure difference between spraying nozzle chamber. This method facilitates fabrication commercial powders without binders as particles directly deposited onto substrate. By optimizing parameters, LiNi0.9Co0.05Mn0.05O2 were successfully developed, their properties compared those wet slurry-coated cathodes. Tape tests confirmed that cathode exhibited better adhesion materials Al foil than cathode. Further, discharge capacity, rate capability up 20 C, cyclability exceeding 200 charge/discharge cycles Specifically, experienced only 38% reduction its initial capacity following owing strong adhesion, whereas degraded 56%, significant material peeling from foil. Consequently, due enhanced greater capability, Therefore, demonstrated potential cathodes, thereby laying groundwork development advanced
