PULSELiON publishes its 23rd Open Access Paper: “Nickel-Rich Cathodes for Solid-State Lithium Batteries: Comparative Study Between PVA and PIB Binders”
The PULSELiON project proudly announces its 23rd Open Access publication, advancing scalable and sustainable solid-state battery technologies.
Published in Molecules (MDPI, 2025, Volume 30, Article 2974), the paper explores a wet-processing method for fabricating composite cathodes using LiNi₀.₉₀Mn₀.₀₅Co₀.₀₅O₂ (NMC955) and the sulfide-based solid electrolyte Li₆PS₅Cl, with two alternative binders: polyvinyl alcohol (PVA) and polyisobutylene (PIB).
The study shows that both binder systems yield conductive and stable cathodes, but PVA-based cathodes outperform PIB-based ones, achieving the theoretical capacity of 192 mAh·g⁻¹ at 1C, while PIB-based cathodes reach 145 mAh·g⁻¹ at C/40. These results highlight the importance of binder–solvent compatibility and support the development of PVDF-free, scalable cathode fabrication for solid-state systems.
