Current Status and Future Perspective in Electric Vehicle Battery Stacking: A Review

Electric powertrain technologies are gaining widespread popularity globally during the transition to e‐mobility. As a result, battery manufacturing technologies for electric vehicles (EVs) are rapidly advancing, with a particular focus on the critical stacking process. The stacking process plays a key role, especially with the growing need for flexibility to accommodate new electrode materials, sizes, and shapes in both lithium‐ion and solid‐state batteries. Despite these advancements, the current academic literature lacks a clear and comprehensive analysis of the stacking process. This study provides a literature survey on EV battery stacking exploring current and future research topics related to lithium‐ion and solid‐state batteries. Grounded on a systematic methodology for literature search, this article presents the latest advances in stacking technology for both lithium‐ion and solid‐state batteries. Based on this analysis and discussion, potential future research directions are proposed offering a structured foundation for future studies toward more efficient and sustainable solutions.
