The quest for improved energy storage is currently one of the most important scientific challenges. The UK is investing heavily in energy storage and renewable energy technologies and is committed to reducing its CO2 emissions by replacing the majority of its electricity generating capacity over the next few decades. Building better batteries is key to the use of electricity in a low-carbon future and for the exploitation of current and next-generation technologies. Current Li-ion batteries based on liquid electrolytes cannot meet the requirements of future applications. The creation of safer, cheaper, recyclable and higher energy density batteries is therefore essential for the electrification of transport and grid-scale storage of energy from renewable resources. This EPSRC New Investigator Award will develop transformative methods that will deliver solutions to these societally and industrially critical problems. Solid-state Li-ion batteries are a rapidly emerging technology with the potential to revolutionise energy storage. This technology utilises solid electrolytes instead of the flammable liquid electrolytes found in current Li-ion batteries. The solid-state architecture has the potential to significantly increase both the safety and energy density of next-generation batteries. Their performance is, however, currently limited by a number of underlying challenges, including the presence of highly resistive interfaces and difficulties in controlling the microstructures of the solid electrolytes that these batteries are built around. These challenges greatly hinder Li-ion transport and are therefore highly detrimental to the operation of the battery. To address these pertinent issues, the team will develop and apply state-of-the-art computational and experimental techniques to provide a fundamental understanding of ion transport at the microscale of solid electrolytes for solid-state batteries. Such an understanding will allow for the design of solid electrolyte microstructures that promote Li-ion transport instead of restricting it. The insights obtained for solid-state batteries in this project will also have direct implications for other battery and energy technologies where the microstructure and solid-solid interfaces again play crucial roles in determining their performance.

目前，寻求改进的能源存储是最重要的科学挑战之一。英国正在大量投资于能源和可再生能源技术，并致力于通过更换未来几十年来替换其大部分发电能力来减少其二氧化碳排放。建造更好的电池是在低碳未来以及当前和下一代技术的开发中使用电力的关键。基于液体电解质的当前锂离子电池无法满足未来应用的要求。因此，创建更安全，更便宜，可回收和更高的能量密度电池对于从可再生资源的运输和网格尺度存储电气至关重要。 EPSRC新研究者奖将开发变革性方法，将为这些社会和工业至关重要的问题提供解决方案。固态锂离子电池是一项快速新兴的技术，具有彻底改变储能的潜力。该技术利用固体电解质，而不是当前锂离子电池中发现的易燃液体电解质。固态结构有可能显着提高下一代电池的安全性和能量密度。但是，目前，它们的性能受到许多潜在的挑战的限制，包括存在高度电阻的接口以及控制这些电池围绕这些电池的固体电解质微观结构的困难。这些挑战极大地阻碍了锂离子的运输，因此对电池的运行非常有害。为了解决这些相关问题，团队将开发和应用最先进的计算和实验技术，以提供对固态电池固体电解质显微镜的离子传输的基本了解。这样的理解将允许设计固体电解质微观结构，这些微结构促进锂离子运输而不是限制它。该项目中固态电池获得的见解也将对其他电池和能量技术产生直接影响，在这些电池和能量技术中，微观结构和固相接口再次在确定其性能中起着至关重要的作用。
