The University of St Andrews and OXIS Energy Ltd will collaborate in order to demonstrate a lithium-sulfur (Li-S) flowbattery. Li-S chemistry has two key advantages; it uses cheap and abundant raw materials; and delivers vastly improvedenergy density in comparison to incumbent technologies. Li-S batteries are therefore cheaper per unit of energy storedthan incumbent technologies. The proposed project will seek to demonstrate how this can be exploited together with anovel Redox Flow Battery (RFB) design to deliver cost effective energy storage at a grid level. The project will demonstratethe operation of a lab scale Li-S RFB. This will involve the design and construction of new test hardware; the developmentof new electrolyte formulations; the testing of novel electrode materials and composites; and finally the investigation ofoperation conditions. The resulting battery will establish the commercial feasibility of the concept for stationary applications,where large battery capacity and low cost are essential. This inexpensive grid-scale battery promises to efficiently connectintermittent renewables to the grid thus increasing energy security while simultaneously reducing both bills and emissions.

圣安德鲁斯大学和Oxis Energy Ltd将进行合作，以证明锂硫（Li-S）流动式。 Li-S化学具有两个关键优势。它使用便宜而丰富的原材料；与现有技术相比，提供了大大提高的增强密度。因此，Li-S电池是每单位能量存储现有技术便宜的。拟议的项目将寻求证明如何与Anovel Redox Flow Battery（RFB）设计一起利用它，以在网格级别提供具有成本效益的能源存储。该项目将展示实验室比例LI-S RFB的操作。这将涉及新测试硬件的设计和构建；新电解质配方的开发；新型电极材料和复合材料的测试；最后是对操作条件的研究。最终的电池将确定该概念对固定应用的商业可行性，在这种应用中，大电池容量和低成本至关重要。这种廉价的网格尺度电池有望有效地将可再生能源连接到网格，从而提高了能源安全性，同时又减少了两项账单和排放。
