Lithium-Ion Battery Microstructure Analysis
🔬 An in-depth understanding of electrode microstructure is essential for developing lithium-ion batteries with higher energy, power, longer lifespan, and enhanced safety.
🔍 3D imaging techniques reveal critical microstructural features, including phase distribution, interfacial surface area, elemental distribution, connectivity, and tortuosity.
📊 These transport parameters are crucial for linking the structure-performance relationship in lithium-ion batteries.

Characterization Methodology
⚙️ Thermo Fisher Scientific dual beam systems coupled with Avizo software enable quantitative analysis of representative 3D volumes to predict battery performance accurately.
🧪 In this specific use case, a high-energy density cathode (NMC 811) was characterized using the Thermo Scientific $\text{FIB-SEM}$ dual beam system with low-voltage 3D EDS mapping.
📏 The resulting 3D dataset featured a reconstruction volume of $226,000 \text{ }\mu\text{m}^3$ with a pixel size of $71 \text{ nm}$.
💻 The reconstructed 3D electrode microstructure serves as an accurate template for performance modeling when analyzed using Avizo software.
