This work demonstrates the development and evaluation of a flexible senor matrix utilising thermistors for distributed in-situ and operando temperature monitoring of lithium-ion cells. The influence of the sensing element on the electrochemical system was proven to be negligible. Furthermore, the flexible sensors were confirmed to be resistant to the mechanical forces imposed during the cell instrumentation procedure and the harsh chemical environment inside Li-ion cells. The sensing methodologies and modification techniques developed in this work can be applied to single cells as well as large scale battery modules and pack systems and integrated within the cell manufacturing process.
