This project focuses on delivering one of the key Industrial Challenge Fund Areas, which is 'the design, development and manufacture of batteries for the electrification of vehicles'. The improved materials, electrodes and devices will be designed, manufactured and validated in two key centres in the UK, which are (1) National Graphene Centre at Manchester and (2) the UK's first full battery prototyping lines in a non-commercial environment at the WMG Energy Innovation Centre. Developments in electrochemical energy storage have transformed our use of personal devices (mobile phones, laptops)and are now poised to bring about a similar transformation in vehicular transport. Electrochemical energy storage (batteriesfor storage of energy, supercapacitors where delivery of power is critical) is also making in-roads to other fields of transport,such as aircraft, and is increasingly a focus for storage of electricity on the "grid" scale. Improvements in energy storagedepend on a chain of technological developments, but the initial one is the development of new electrochemistry/electrodematerials, which allows more energy to be stored and/or higher power extraction.The advent of 2D materials, sparked by the isolation of graphene (2-dimensional carbon) and understanding of itsexceptional physical properties, has ignited enormous interest in the application of this family of materials as electrodes,with the express goals of improving existing storage approaches, and of developing new electrochemical storage methods.Although initial results with graphene, in both the battery and supercapacitor contexts, have been promising subsequentwork has shown that the strong thermodynamic tendency of graphene sheets to re-aggregate (to graphite) means thatinitial improvements in performance are generally not retained over repeated cycles. The approach that we concentrate on in this work is to use so-called heterostructures, solution phase mixturesof more than one 2D material, as our composite electrode material.A second point is that 2D materials are often only available on a very small scale, thus testing of theirperformance in electrochemical storage technologies is frequently performed on scales that are too small to berepresentative of realistic devices, particularly with regard to transport applications. Again, we will address this challenge byexploiting our own (patented) method to "exfoliate" 2D materials, which is scaleable, and by building in porosity to theelectrode design when scaling the electrode preparations up. Finally, we will test the assembled large scaledevices under realistic operational conditions and use the results of that testing to inform further optimisation of thematerial preparation and the electrode formulation. The proposal aligns strongly with the Industrial Strategy Challenge Fund objectives in that it: 1: has strong support from a range of UK businesses (right across the value chain from small materials processing firms to end users such as JLR) and thereby increases UK businesses' investment in R&D and improved R&D capability and capacity; 2: the work is a collaboration between a Chemist (Manchester), Chemical Engineer (WMG) and Electrical Engineers (Manchester), and thus provides multi- and interdisciplinary research around the challenge areas of the ISCF; 3: the project will increase business-academic links in areas relating to the challenge areas, specifically as development of new electrode materials, novel methods to study degradation and to model cell performance are important components of this work 4: the project will increase collaboration between younger, smaller companies (eg Archipelago) and larger, more established companies up the value chain (eg Johnson Matthey, JLR); 5: Successful prosecution of the project will increase overseas investment in R&D in the UK, given the direct links to overseas-owned industries in the project.

该项目的重点是提供关键的工业挑战基金领域之一，即“汽车电气化电池的设计、开发和制造”。改进的材料，电极和设备将在英国的两个关键中心设计，制造和验证，这两个中心是（1）曼彻斯特的国家石墨烯中心和（2）WMG能源创新中心的英国第一个非商业环境中的全电池原型生产线。电化学能量存储的发展已经改变了我们对个人设备（移动的电话、笔记本电脑）的使用，现在正准备给车辆运输带来类似的转变。电化学能量存储（用于存储能量的电池，超级电容器，其中电力输送是关键的）也正在进入其他运输领域，例如飞机，并且越来越多地关注“电网”规模的电力存储。能量存储的改进取决于一系列技术发展，但最初的技术发展是新的电化学/电极材料的发展，这使得更多的能量被存储和/或更高的功率提取。（二维碳）和对其特殊物理性质的理解，已经点燃了人们对这一系列材料作为电极的应用的巨大兴趣，其明确的目标是改进现有的存储方法，并开发新的电化学存储方法。已经有了很好的前景，研究表明，石墨烯片重新聚集（成石墨）的强烈热力学趋势意味着性能的初始改善通常不会在重复循环中保持。我们在这项工作中集中精力的方法是使用所谓的异质结构，一种以上2D材料的溶液相混合物，作为我们的复合电极材料。第二点是2D材料通常只能在非常小的规模上获得，因此在电化学存储技术中对其性能的测试经常在太小而不能代表现实设备的规模上进行，特别是在运输应用方面。同样，我们将通过利用我们自己的（专利）方法来“剥离”2D材料来应对这一挑战，这是可扩展的，并且在电极制备时将多孔性构建到电极设计中。最后，我们将在实际操作条件下测试组装的大规模设备，并使用测试结果来进一步优化材料制备和电极配方。该提案与工业战略挑战基金的目标高度一致，因为它：1：得到了一系列英国企业的大力支持（从小型材料加工企业到捷豹路虎等最终用户的整个价值链），从而增加英国企业在研发方面的投资，提高研发能力和产能; 2：这项工作是一位化学家（曼彻斯特），化学工程师（WMG）和电气工程师（曼彻斯特），从而围绕ISCF的挑战领域提供多学科和跨学科的研究; 3：该项目将加强与挑战领域有关的领域的商业-学术联系，特别是因为开发新的电极材料、研究退化和模拟电池性能的新方法是这项工作的重要组成部分4：该项目将加强年轻、规模较小的公司之间的合作，（如Archipelago）和更大、更成熟的公司，（例如约翰逊万丰，捷豹路虎）; 5：该项目的成功起诉将增加海外对英国研发的投资，因为该项目与海外拥有的行业有直接联系。
