PREVENTING KESSLER SYNDROME

with Graphene-Enabled SERS-Based Gas Sensors for Early Detection of Failure in Li-Ion Batteries

Abstract:
In this presentation, we explore how lithium-ion batteries—powering everything from smartwatches and electric vehicles to satellites—can sometimes fail dramatically, posing serious risks. Detecting such failures early is vital for safety, yet traditional sensors often react too slowly or lack specificity. We introduce the proof-of concept for an innovative gas sensor using surface-enhanced Raman spectroscopy (SERS), which combines silver nanoparticles arranged in a periodic pattern covered by a graphene layer. This unique setup significantly enhances the detection sensitivity for early-stage electrolyte vapor leaks, potentially allowing detection far sooner than current technologies. Our work paves the way toward safer battery management systems in electric vehicles, aerospace missions, and everyday electronic devices.

The seminar takes place at 15:00 Berlin time (this is 16:00 in Lithuania)
