🔋 Calendering‐Dependent Electrochemical and Cost‐Energy Tradeoffs in Layered – Olivine Blend Cathodes
📝 کالندرینگ کاتدهای مخلوط NMC/LMFP حد بهینهای دارد؛ مخلوط ۷۰/۳۰ مزیت نرخ را حفظ میکند اما ۵۰/۵۰ با چگالش دچار محدودیت انتقال و افت چرخهپذیری میشود.

💡 Novelty & Significance:
This study uniquely links calendering intensity to electrochemical and cost-energy tradeoffs in NMC/LMFP blend cathodes, revealing composition-dependent densification limits absent in NMC alone. It shows moderate calendering preserves rate benefits in 70/30 blends, while hard calendering degrades both blends. Nb-stabilized NMC further improves cyclability and energy retention, offering a practical pathway to optimize microstructure, durability, and cost.
