While Chinese companies like BYD and CATL dominate Cuba’s battery imports, local innovators are punching above their weight. The University of Havana’s nickel-zinc battery prototype (using mined local nickel) could cut costs by 30%.
[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] With their small size, lightweight, high-temperature performance, fast recharge rate and longer life, the lithium-ion battery has gradually replaced the traditional lead-acid battery as a better option for widespread use in the communication energy storage system and more industrial fields.
