While lithium-ion dominates today, the Seychelles Energy Commission is eyeing vanadium flow batteries. Why? Their liquid electrolyte is about as likely to combust as a sleeping sea turtle. Plus, they can store 8+ hours of energy – perfect for those loooong tropical nights.
[pdf] In a recent presentation at the Electrochemical Society symposium, insights from a decade of vanadium flow battery development were shared, emphasizing the importance of testing at various scales, addressing safety and reliability issues early, and the challenges faced with the commercialization of mixed-acid electrolytes, particularly concerning chlorine gas generation during deployments.
[pdf] Good thermal management helps keep battery systems safe. It also makes them work better and last longer. – Liquid cooling is best for big battery systems. It controls temperature well and helps batteries last longer. – Air cooling is good for small systems.
