| Abstract Scope |
Growing demand for electric vehicles, grid storage, and renewable energy has intensified the need for improved lithium-ion batteries. Meeting these performance targets requires multifunctional electrodes with engineered microstructure properties, yet conventional slurry casting is limited by process constraints. This motivates alternative manufacturing methods capable of producing improved electrode characteristics.
We have advanced the innovation of electrophoretic deposition (EPD) to manufacture multifunctional composite electrodes. A systematic strategy for co-depositing multi-materials of LiFePO₄ (LFP), carbon nanotubes (CNTs), and solid-state electrolyte (LiCGC) particles into transport-engineered architectures. CNTs form a robust conductive network outperforming carbon black, while LiCGC reduces interfacial and bulk impedance, enhancing ion/electron transport.
The presentation will show (i) CNT-supported conductive frameworks via EPD, (ii) integrated co-deposition of LFP, CNT, and LiCGC, and (iii) scalable fabrication of flexible, low-impedance electrodes. These findings demonstrate EPD effectiveness and provide transferable insights for other multi-material applications, including structural battery of load-bearing complex shapes. |
