Accurate measurement of essential operational parameters in electrochemical energy storage devices is vital for ensuring reliable and long-lasting performance in a circular economy. This study presents the first use of a Lossy Mode Resonance (LMR) optical fibre sensor to measure the temperature of lithium-ion batteries, which is a highly influential aspect of their degradation. This technique enables an effective and simple application of optical fibre sensors for energy storage devices. The design involves using a U-shaped fibre to accurately detect changes in absorption, rather than changes in wavelength. Additionally, it incorporates a thin-film of graphene oxide and polyethyleneimine to induce the LMR which is enclosed within polydimethylsiloxane which alters refractive index with temperature. The total sensitivity reached is -0.0072 A.U./°C and -0.39 nm/°C, with excellent linearity values of R² 0.98 and R² 0.99 for the 2 C and 2.5 C discharge rates, respectively. This work emphasises the affordable, accurate, and innovative use of LMR sensors, which encourages the advancement and utilisation of these sensors in electrochemical energy storage systems.
