Magnesium-antimony liquid metal battery for stationary energy storage.
نویسندگان
چکیده
Batteries are an attractive option for grid-scale energy storage applications because of their small footprint and flexible siting. A high-temperature (700 °C) magnesium-antimony (Mg||Sb) liquid metal battery comprising a negative electrode of Mg, a molten salt electrolyte (MgCl(2)-KCl-NaCl), and a positive electrode of Sb is proposed and characterized. Because of the immiscibility of the contiguous salt and metal phases, they stratify by density into three distinct layers. Cells were cycled at rates ranging from 50 to 200 mA/cm(2) and demonstrated up to 69% DC-DC energy efficiency. The self-segregating nature of the battery components and the use of low-cost materials results in a promising technology for stationary energy storage applications.

Renewable power sources are a promising alternative to the electrical generation by conventional sources of energy, limiting the emissions to the atmosphere and reducing the dependence on coal or oil. But some of these sources (wind or sun) have one major drawback, which is their variability. Apart from that, electricity production has to match the demand at any moment, so the supply systems ar...
