The temperature on the surface of batteries can typically be monitored by various temperature sensors and infrared thermal imaging equipment. The internal temperature of LIBs increases during its operating cycle in direct proportion to the generated heat amount .
Both constant current cycling and cyclic voltammetry were employed to link the optical response to the charge and discharge of the battery cells, and the results demonstrated that the optical signal changed consistently with lithium ion insertion and extraction.
Currently, the field of optical fibre sensing for batteries is moving beyond lab-based measurement and is increasingly becoming implemented in the in situ monitoring to help improve battery chemistry and assist the optimisation of battery management [4, 6].
As technology progresses, fiber optic sensors are poised for widespread use in implantable sensing for LIBs, intelligent management, and thermal runaway warning, improving the precision and reliability of battery monitoring. Such sensors are a future direction for monitoring the health of LIBs.
Fiber–optic battery monitoring methods, which are advantageous because of their low cost, compactness, remote sensing capabilities, and simple integration without interfering with internal chemistry, are recently reported.
