Preprint for "Battery Thermal Management Systems: A Comprehensive Review"

The paper comprehensively reviews the various thermal management systems utilized in small-to-medium battery packs as well as large-scale battery energy storage systems. A broad categorization of thermal management systems is provided. Recent developments regarding passive, active, and hybrid options are then discussed in terms of air-, liquid-, phase change materials-, and heat pipes-based solutions. The suitability of different heat transfer liquids and heat transfer-enhancing additives is also considered in the context of the individual thermal management options. Finally, the paper provides a brief review of the safety concerns associated with electrochemical energy storage technologies and the common mitigation strategies regarding thermal runaway.
