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.

圣安德鲁斯大学和奥克西斯能源有限公司将合作展示一种锂硫(Li-S)流体电池。锂S化学有两个关键优势：它使用廉价而丰富的原材料；与现有技术相比，它提供的能量密度大大提高。因此，锂S电池每单位储能比现有技术更便宜。拟议的项目将试图展示如何将这一点与另一种氧化还原液流电池(RFB)设计结合起来，在电网级别提供具有成本效益的能量存储。该项目将演示实验室规模的Li-S重油催化裂化装置的运行。这将涉及新测试硬件的设计和建造；新电解液配方的开发；新型电极材料和复合材料的测试；以及最后操作条件的调查。由此产生的电池将为固定式应用确立这一概念的商业可行性，在固定式应用中，大电池容量和低成本是必不可少的。这种廉价的电网规模电池有望有效地将间歇性可再生能源连接到电网，从而提高能源安全性，同时减少账单和排放。
