| Abstract Scope |
Growing demand for electric vehicles is accelerating the need for lithium-ion batteries with higher energy densities and lower cost. Lithium iron phosphate (LFP) has emerged as a promising cathode material owing to its environmental sustainability, thermal stability, and affordability. However, its widespread adoption remains limited by its relatively low energy density and high ionic resistance, especially in thick-film electrodes required for high-capacity applications. In this presentation, I will discuss advanced electrode engineering strategies to realize low-resistance LFP thick-film electrodes. The first approach involves a dual-layer design that tailors the porosity distribution between the upper and lower regions of the electrode to optimize ion and electron transport pathways. The second approach focuses on a dry electrode fabrication method, a recently highlighted, ecofriendly, and solvent-free manufacturing process. This presentation will explore the advantages enabled by these two strategies and demonstrate how they can overcome the intrinsic limitations of conventional LFP-based batteries. |
