This paper provides a comprehensive review of thermal management strategies for cylindrical lithium-ion battery packs, focusing on enhancing performance, safety, and lifespan. The review covers four major techniques: air cooling, liquid cooling, phase-change materials (PCM), and hybrid methods. Air cooling is analyzed for its simplicity and cost-effectiveness, while liquid cooling systems are explored for their superior heat dissipation capabilities. Phase-change materials are evaluated as potential passive cooling solutions due to their latent heat absorption and release properties. Hybrid methods, which combine two or more strategies, are discussed for their synergistic effects in achieving optimal thermal management. Each strategy is assessed in terms of thermal performance, energy efficiency, cost implications, and applicability to cylindrical lithium-ion battery packs. The paper offers valuable insights into the strengths and limitations of each technique, providing a comprehensive guide for researchers, engineers, and policymakers in the field of energy storage. The findings contribute to ongoing efforts to develop efficient and sustainable thermal management solutions for cylindrical lithium-ion battery packs in various applications.This paper provides a comprehensive review of thermal management strategies for cylindrical lithium-ion battery packs, focusing on enhancing performance, safety, and lifespan.
