Join Us for the Next Battery2030+ Webinar: Applications of Non-linear Spectroscopy in Battery Science
Join us online on 19 February 2026 at 15:00 CET for the next session of the Battery2030+ webinar series, exploring how advanced spectroscopic techniques can reveal the microscopic processes governing ion transport and interfaces in solid-state batteries.
Our project, together with OPERA and ULTRABAT, is introducing this initiative under the framework of Battery2030+. The series, titled “Time and Length-Scale Operando Bridging Techniques to Study Battery Interfaces,” is designed to familiarise scientists with experimental methods that make it possible to study interfacial processes in real time.
Understanding Ion–Lattice Dynamics in Solid-State Batteries
Solid-state batteries are considered one of the most promising technologies for next-generation energy storage. However, many of the key processes governing their performance occur at the microscopic level and remain difficult to observe directly.
Lattice vibrations play a crucial role in solid-state ion transport, yet their exact influence on ion mobility and interfacial behaviour is still not fully understood. Advanced spectroscopic approaches offer new opportunities to study these interactions and build a clearer picture of how ions move through solid electrolytes.
Non-linear spectroscopy techniques such as THz/IR, Raman and X-ray spectroscopy provide valuable insights into ion–lattice dynamics. When combined with modelling and simulation, they enable researchers to explore how structural and vibrational properties influence ionic conductivity, interfacial stability and overall battery performance.
Webinar Format
Each webinar combines two complementary parts:
1️⃣ A short tutorial introducing one or more experimental techniques, followed by a brief break.
2️⃣ A research talk demonstrating how these techniques are applied in current studies.
This format supports both knowledge transfer and lively discussion among researchers from different disciplines.
Upcoming Webinar: Applications of Non-linear Spectroscopy in Battery Science
The upcoming session will feature:
Raj Pandya (University of Warwick)
Topic: Applications of Non-linear Spectroscopy in Battery Science
In this webinar, the speaker will present recent research on how non-linear spectroscopic techniques can reveal microscopic processes in solid-state ionic conductors. The talk will focus on what can be learned from THz/IR, Raman and X-ray spectroscopy about ion–lattice dynamics and the practical challenges associated with applying these methods to battery materials.
Using the solid electrolyte Li₇La₃Zr₂O₁₂ (LLZO) as a case study, the presentation will compare tetragonal and doped cubic phases to demonstrate how spectroscopy and simulations can be combined to build a detailed understanding of lithium-ion transport in solid-state systems. The seminar aims to provide a clearer mechanistic picture of ion transport processes and their impact on the performance and stability of next-generation batteries.
Building Collaboration Through Knowledge
This webinar series represents a joint effort by OPINCHARGE, OPERA, and ULTRABAT to bring together Europe’s battery research community around advanced characterisation methods, strengthen collaboration, and accelerate innovation in interface science
