ICSF Wave 1: GENESIS: Garnet Electrolytes for New Energy Storage Integrated Solutions

便携式电子产品的繁荣是由锂离子电池技术的进步推动的，此前古德足够和他的同事们最初研究了锂钴氧化物正极材料。在含磷阴极方面的其他显着进展将锂离子电池的应用扩展到更高充放电速率的应用，如电动工具和交通工具。由于混合动力汽车和全电动汽车对环境的好处，在后者方面的应用加剧了人们对锂离子电池的浓厚兴趣。还提出了作为可再生能源储能的进一步应用，以克服太阳能或风能等可再生能源供应问题的间歇性。在锂离子电池新电极材料研究深入的同时，新电解液材料的开发却相对较少受到关注。在典型的锂离子电池中，由于这种体系具有较高的锂离子导电性，在有机溶剂中的电解液通常是锂盐。这种电解液的易燃、有毒和易挥发的性质、与高电压电极材料相结合的不稳定性，以及对小型化的渴望，都对传统液体电解液电池的进一步发展构成了明显的限制。固态电解液的使用使我们有可能克服这些问题，同时提供一系列其他的进步，包括简化高压电池组的生产。固态电池的另一个独特优势是其低泄漏电流，这在能量收集设备方面提供了其他潜在的应用。此外，对形状灵活、可穿戴的电子设备的需求为开发所有固态电池系统提供了另一条途径。因此，这个涉及化学、材料科学、化学工程和工业研究人员的跨学科项目旨在开发新型固态锂离子电池。这种全固态电池已被确定为电池研究中最重要的未来目标之一，正如它们被列为法拉第挑战(行业战略挑战目标2)快车道项目之一所表明的那样。这些电池的重要性在于它们有潜力提供更好的安全性、更小的尺寸和更高的容量，以及开辟新的应用，如能量收集设备。特别是，展示一种商业上可行的、具有更高安全性的可伸缩陶瓷基电解液将在英国创造财富/投资机会方面提供巨大好处(行业战略挑战目标1)。在潜在商业化方面，石榴石锂离子导电电解液的优化、其放大合成和在全固态电池中的演示在锂离子电池技术方面提供了巨大的潜力，应用范围从便携式消费设备到交通运输。在帮助确保在这一领域产生影响方面，已经与工业界建立了强有力的联系，从工业界的角度为项目提供关键投入，并对最有希望的系统进行全电池测试的工业界验证(工业界战略挑战目标3)。这将使英国工业能够利用在这项工作中取得的进展，并提供一条早期开发的途径(行业战略挑战目标1)。

The portable electronics boom has been driven by advances made in Li ion battery technology, following the initial work on the lithium cobalt oxide cathode material by Goodenough and co-workers. Other notable advances in terms of phosphate containing cathodes have extended the applications of lithium ion batteries to higher charge/discharge rate applications such as power tools and transport. Applications in terms of the latter have intensified the already substantial interest in lithium ion batteries, as a result of the environmental benefits of hybrid and all electric cars. Further applications as energy storage for renewable sources have also been proposed to overcome the intermittency of supply problems of renewable energy sources such as solar or wind power. While research on new lithium ion battery electrode materials has been intensive, the development of new electrolyte materials has received comparatively less attention.In a typical Li ion battery, the electrolyte is usually a Li salt in an organic solvent, as a result of the high Li ion conductivity of such systems. The flammable, toxic and volatile nature of such electrolytes, the instability in conjunction with higher voltage electrode materials, and the desire for miniaturisation are placing distinct limitations on further advances with conventional liquid electrolyte batteries. The use of a solid state electrolyte allows the potential to overcome these problems along with supplying a range of other advances including the simplified production of high voltage battery packs. A further unique advantage of solid state batteries is their low leakage currents, which delivers other potential applications in terms of use in energy harvesting devices. Furthermore the desire for shape-flexible, wearable electronic devices offers another avenue for the exploitation of all solid state battery systems. This interdisciplinary project involving researchers from chemistry, materials science, chemical engineering and industry aims therefore to develop new Solid State Li ion batteries. Such all solid state cells have been identified as one of the most important future targets in battery research, as illustrated by their inclusion as one of the fast-track projects in the Faraday challenge (industry strategy challenge objective 2). The importance of these batteries lies in their potential to deliver improved safety, reduced size, and higher capacity, as well as to open up new applications such as energy harvesting devices. In particular, the demonstration of a commercially viable scaleable ceramic-based electrolyte with higher safety will offer large benefits in terms of UK wealth generation/investment opportunities (Industry strategy challenge objective 1). In terms of potential commercialisation, the optimisation of garnet Li ion conducting electrolytes, their scale-up synthesis and demonstration in all solid state batteries offers significant potential in terms of Li ion battery technology, with applications ranging from portable consumer devices to transport. In terms of helping to ensure the delivery of impact in this area, a strong link has already been set up with industry, to provide key input into the project from an industrial viewpoint, along with industrial validation of the full cell tests on the most promising systems (industrial strategy challenge objective 3). This will allow UK industry to capitalise on the developments made during this work and offer an early route to exploitation (Industry strategy challenge objective 1).
