Sem VI (2024-2025)

This course on "Energy Storage and Conversion Systems" provides a comprehensive understanding of various energy storage technologies and their applications in modern energy systems. It begins with an introduction to the need for energy storage, covering methods like flywheel, electrical, magnetic, and chemical storage, including hydrogen and synthetic fuels. The course explores superconducting magnet energy storage (SMES) and supercapacitors, focusing on electrochemical double-layer capacitors (EDLC), pseudocapacitors, and their differences from conventional capacitors and batteries. In the second module, students learn about battery technology, including its history, electrochemistry, electrical characteristics, and mathematical models, with an emphasis on recent advancements in lithium-ion and solid-state batteries. The third module addresses the classification of batteries, such as lead-acid, nickel-cadmium, and lithium-ion, and covers battery pack systems, protection, thermal management, and disposal methods. Direct energy conversion is explored in Module IV, focusing on thermoelectric and thermionic generators, their efficiency, and applications. Finally, Module V covers fuel cells, discussing different types, including alkaline, phosphoric acid, PEM, molten carbonate, and solid oxide fuel cells, along with their working principles, efficiency, and practical uses. This course equips students with the knowledge to engage with and contribute to advancements in energy storage and conversion systems.
