Abstract
Smart battery cell concept, cells with integrated sensors, becomes more important as battery manufac-turer tend to manufacture larger capacity packs to meet electrification demand. In order to accomplish smart cell concept in battery cells first step is accurate perception of battery states. However, conven-tional sensors are not able to measure parameters precisely. Furthermore, these bulky conventional sensors add significant weight resulting in significant loss in energy/kg density, thereby limiting the fea-sible quantity and therefore spatial coverage. This study presents a thin-film temperature sensor designed for battery monitoring. A thin layer (total <150 nm) of Alumel & Cromel (K-type thermocouple)are sputtered onto a newly developed TECASUB PEEK LDS (Polyether ether ketone). The sensor was tested externally on cylindrical cell and successfully capture temperature gradients with 1C cycling test.
