Investigating plasmonic based fibre optic sensing as a battery diagnostic technique

Abstract

This study demonstrates for the first time the application of plasmonic based fibre optic sensors inside Lithium-ion pouch cells. The study shows the successful integration of the sensor platform into battery cells, acquisition of diagnostic data in-situ and in real time, correlation of data to battery internal process phenomena and demonstration of negligible impact of the sensor presence on battery cell function. This study demonstrates the potential of plasmonic based fibre optic sensors as a battery cell diagnostic technique and can also be considered within the wider field of fibre optic based battery diagnostics.
