Special Issue Information

Dear Colleagues,

With the mandate of short-hull passenger flights by all-electric airplanes in 2040, the safety of battery systems never been of such great importance. Although batteries have successfully paved their way to the automotive industry, aerospace organizations continue to express concerns about battery safety. The academic and industrial communities thus need to extend their battery research that has so successfully accelerated the electrification of passenger cars into the future of air transport. To address these new challenges and opportunities, this Special Issue will focus on battery safety concerns and their diagnostic methodologies. Therefore, the topics of the contributions include but are not limited to:

  • Review of battery safety methodologies;
  • Recent progress on battery safety performance;
  • Novel methodologies for battery safety characterization;
  • Novel technologies for safer batteries;
  • Experimental studies to evaluate battery safety performance;
  • Battery safety modeling;
  • Autopsy studies of failed battery pack/module/cell;
  • New cell/module/pack design to improve battery safety performance;
  • Lighter, safer materials/design of battery pack for aerospace applications.

In an electric vehicle, a large number of lithium-ion cells are connected in parallel. While cells in parallel increase the reliability of the battery pack, it increases the probability of current imbalance between the parallel branches, thus ageing gradient. The current peak in a cell also can exceed the maximum charge current capability of the cell; leading to lithium plating, therefore a safety issue. The temperature gradient within a battery pack amplifies this issue. This work reports the impact of such temperature gradient on current imbalance within parallel connected cells, their long-term impact on degradation and evaluation of current distribution with degradation. Employing a real-world relevant experimental setup, a total of 1400 cycles were performed on a module with four cells in parallel. A temperature gradient of 10 °C was introduced among the cells, and current in individual parallel branches was measured employing Hall-effect sensors. Over the course of the experiment, module capacity decreased by 23.6%. Cells at higher temperature/lower exposure to active cooling experienced higher degradation. However, the cell with the lowest starting capacity, although exposed to nominal module temperature and cooling experienced the highest current amplitude towards the end of discharge/charge and thus the highest resistance degradation. It was found that current in an individual parallel branch was exceeding the maximum rated charge/discharge current by 53%. Full article
