Operando neutron diffraction has emerged as a powerful tool for probing the internal dynamics of solid-state batteries (SSBs). Unlike X-rays, neutrons penetrate dense materials like lithium metal and ceramic electrolytes without significant attenuation, enabling real-time monitoring of structural changes during cycling. A 2023 study using the Spallation Neutron Source (SNS) achieved a temporal resolution of 1 second and spatial resolution of 10 µm, capturing the formation and propagation of lithium dendrites in SSBs with unprecedented clarity.
This technique has also shed light on the mechanical stresses induced by volume changes in electrode materials during charge-discharge cycles. For instance, operando neutron diffraction revealed that silicon anodes experience compressive stresses exceeding 500 MPa during lithiation, leading to crack formation and capacity loss. By correlating these stresses with electrochemical performance metrics such as Coulombic efficiency (CE), researchers have developed strategies to mitigate mechanical degradation through nanostructured electrode designs.
Moreover, operando neutron diffraction has provided critical insights into the interfacial phenomena between solid electrolytes and electrodes. Studies have shown that interfacial resistance can increase by up to 50% within the first 100 cycles due to chemical reactions and lattice mismatches at the interface. These findings have guided the development of buffer layers with tailored thermal expansion coefficients (<5 ppm/K), reducing interfacial resistance by over 30%.
The scalability of this technique is being enhanced through portable neutron sources and advanced data processing algorithms capable of handling gigabyte-scale datasets in real time. A recent collaboration between academia and industry demonstrated that operando neutron diffraction could be integrated into battery manufacturing lines for inline quality control, reducing defect rates by 15%. This represents a significant step toward commercialization of SSBs.
