Researchers at Zhengzhou University, Tsinghua University and Stanford University have developed a solid-electrolyte-based liquid Li-S and Li-Se (SELL-S and SELL-Se, respectively) battery system with the potential to deliver energy densities exceeding 500 Wh kg -1 and and 1,000 Wh L -1 , together with the ability of low-cost and stable electrochemical performance for future concentrated and large-scale storage applications. The batteries use a Li 6.4 La 3 Zr 1.4 Ta 0.6 O the (LLZTO) ceramic tube as electrolyte and work at temperatures higher than the melting point of lithium. Polysulfide or polyselenide shuttle effects and lithium dendrite growth are effectively prevented, and high energy density, together with high stability, fast charge/discharge capability, high Coulombic efficiency, and high energy efficiency, can be achieved. A paper on their work is published in the journal Joule . The current state-of-the-art lithium-ion batteries (LIBs) have an energy density of less than 300 Wh […]
