本项目将获得关于超级电容器装置中石墨烯电极实际性能的准确数据，其规模对现实世界的应用具有技术意义。这将通过研发活动实现，包括石墨烯墨水的生产，以及将石墨烯墨水集成到电极中，用于随后制造超级电容器、硬币和储袋电池。这种装置的具体应用是在低碳汽车的储能方面。该项目直接回答了一个关键问题，即石墨烯在实际应用中制造成实际产品时是否会保持其新颖的性质。研究活动的目标是确定石墨烯的选择和质量，制造和优化用于真正的超级电容器设备的石墨烯油墨和电极。一项关键的创新将是从材料到制造的综合材料科学和扩大工程方法，以便将实验室发现的石墨烯的性能优势转化为实际产品。华威大学的贡献贯穿整个项目计划，旨在在英国内部的材料科学和制造能力的战略整合方面取得根本性进展。一个关键的贡献是开发了一种全面的方法来评估石墨烯电池的高通量，该方法将把石墨烯的等级和制造方法与石墨烯设备的能量和功率密度特性联系起来。通过WMG高价值制造(HVM)弹射器内独特的设施和行业/学术网络，基于石墨烯的新型储能设备(纽扣电池和超级电容器电池)的成功放大和后续表征的真实展示将推动关键行业(如运输和能源)的信心，加速石墨烯研究并刺激英国供应链。

Project SummaryThis project will obtain accurate data on the practical performance of graphene electrodes within a supercapacitor deviceon a scale that is of technological interest for real world application. This will be achieved through R&D activities ingraphene inks production and integration of graphene inks into electrodes for subsequent manufacturing of supercapacitorcoin and pouch cells. The specific application of such devices is in energy storage for low carbon vehicles. The projectdirectly answers the key question of whether graphene will retain its novel properties when manufactured into real productsfor practical applications. Research activities are targeted at identifying the choice and quality of graphene, manufactureand optimise graphene inks and electrodes for a real supercapacitor device. A Key innovation will be an integrated materialsciences and scale-up engineering approach from materials to manufacturing in order to translate the performance benefitsof graphene from lab discovery into real products.The Warwick University contribution cross-cuts the complete project programme and aims to deliver a fundamentaladvancement in the strategic integration of material science and manufacturing capability within the UK. A key contributionis the development of a comprehensive methodology for the high throughput assessment of graphene cells, which willrelate the graphene grade and manufacturing method with the energy and power density characteristics of the graphenedevices. Through the unique facilities and industry/academic networks within the WMG High Value Manufacturing (HVM)Catapult, a real-world demonstration of the successful scale-up and subsequent characterisation of new graphene basedenergy storage devices (button cells and supercapacitor cells) will drive confidence within keys sectors (e.g. transport andenergy), accelerate graphene research and stimulate a UK supply-chain.
