The rapid development of lithium-ion battery technology has led to the emergence of different cell designs, namely prismatic and cylindrical cells. This presentation explores the key differences between prismatic and cylindrical cells and their implications for thermal propagation management in lithium-ion batteries. Design considerations to prevent thermal hazards in batteries are examined, including thermal runaway and overheating. The impact of fast charging on cylindrical and prismatic cells is discussed, highlighting the challenges and potential solutions to mitigate thermal issues during high-rate charging. Furthermore, strategies to improve battery life cycles are explored, focusing on both cell designs. The presentation also sheds light on the production advantages of cylindrical cells, such as cost-effectiveness and scalability. Finally, the talk delves into new strategies to mitigate thermal propagation, including advanced cell packaging, active thermal management systems, and improved electrode materials. By addressing these challenges and implications, this presentation aims to contribute to the development of safer and more efficient lithium-ion battery systems.
