Graphene Electrodes for Automotive Supercapacitor Energy Storage (GRAPHELEC)

该项目将获得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。这将通过石墨烯油墨生产的研发活动以及将石墨烯油墨集成到随后制造超级电容器或硬币和袋状电池的电极中来实现。这种装置的具体应用是低碳汽车的储能。该项目直接回答了石墨烯在制造成实际应用的真实产品时是否会保留其新颖特性的关键问题。研究活动的目标是确定石墨烯的选择和质量，为真正的超级电容器设备制造和优化石墨烯墨水和电极。一个关键的创新将是整合材料科学和从材料到制造的规模化工程方法，以便将石墨烯的性能优势从实验室发现转化为实际产品。华威大学的贡献贯穿了整个项目计划，旨在为英国材料科学和制造能力的战略整合提供根本性的进步。一个关键的贡献是开发了一种用于石墨烯电池高通量评估的综合方法，该方法将石墨烯等级和制造方法与石墨烯器件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，新型石墨烯储能设备（纽扣电池和超级电容器电池）的成功规模化和后续表征的真实演示将推动关键部门（例如运输和能源）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.
