About
The safety, durability, and power density of lithium-ion batteries (LIBs) are currently inadequate to satisfy the continuously growing demand of the emerging battery markets. A reliable battery management system (BMS) is critical to fulfil the expectations on the reliability, efficiency and longevity of LIBs systems. The lifecycle management of LIBs highly rely on the accurate monitoring of battery state and cell parameters (e.g., temperature, voltage, current, impedance, stress, gas generation, etc.). Mitigating thermal runaway (TR) has been regarded as the primary important task for the safe operation of LIBs. Up to now, the thermal management of LIBs rely on the external temperature sensor to detect the cell temperature at device level. However, this delayed temperature sensing fails to provide local, early, and accurate warning of TR process especially for the LIBs with larger size. Meanwhile, the temperature distribution exhibits significant ununiform temperature gradient for different components of batteries (e.g., tabs, electrodes, current collectors, etc.). Unfortunately, limited efforts have been devoted to developing distributed temperature sensors for the large-areal and synchronous temperature measurement. Furthermore, additional thermal-coupled stress will be produced during battery operation under elevated operating temperature, which will lead to distinct morphologic and structural change yet lack in-depth understanding and monitoring. Consequently, many of the reported simulation algorithms in BMS which only base on the external temperature sensing cannot provide admirable battery management.
To address the above issues, the successful candidate will undertake a project to develop integrated sensing framework to real-time monitor the battery status and provide deep insights into the battery degradation analysis. The PhD researcher will have the opportunity to work with a team with wide expertise in nanofabrication technologies, electrochemistry, materials characterisation, energy storage and conversion devices.
