A paradigm shift in energy storage technology is needed to support the transition towards the climate-neutrality set by the EU’s international commitments under the Paris Agreement, while ensuring the targets of EU’s Action Plan on Critical Raw Materials (CRMs). In this context, GREENCAP joins a multi-disciplinary consortium with 5 Universities, 1 R&D Institute, 5 companies, located in 7 European countries including Italy, Germany, France, Ireland, United Kingdom, Estonia, and Netherlands, to unlock the full potential of supercapacitors (SCs) as electrochemical energy storage systems. We will develop a CRM-free technology exhibiting a battery-like energy density (>20 Wh/kg, >16 Wh/L), together with the distinctive superior power densities and high cycle life of traditional electrochemical double layer capacitors. GREENCAP will exploit layered 2D materials, including graphene and MXenes as electrode materials, and ionic liquids (ILs) as high-voltage electrolyte. The main objectives of GREENCAP are: i) to syntheses/ functionalize graphene and MXenes via facile, scalable and sustainable (CRM-free) methodologies, assuring both high surface area and ion accessibility, introducing Faradaic charge storage mechanisms, and improving their quantum capacitance; ii) to produce novel non-/ low-toxic and non-/low-flammable IL-based electrolyte with high conductivities, and a high electrochemical/thermal stability, ensuring SC operation at voltage > 3.5 V within -50°C to +100 °C temperature range, thus eliminating the need for sophisticated cooling systems; iii) to validate the novel SC technology at industrial scale by fabricating cylindrical cells at a TRL 6 while ensuring the creation/existence of the complete value chain from material to cell producers; iv) to produce a novel supercapacitor management system, enabling the full potential of the GREECAP’s SCs in high-end applications, and ensuring their integration into the circular economy.

能源存储技术需要实现范式转变，以支持欧盟在《巴黎协定》下的国际承诺所设定的气候中立过渡，同时确保欧盟关键原材料行动计划（CRM）的目标。在这种情况下，GREENCAP加入了一个多学科联盟，其中包括5所大学，1个研发机构，5家公司，位于7个欧洲国家，包括意大利，德国，法国，爱尔兰，英国，爱沙尼亚和荷兰，以释放超级电容器（SC）作为电化学储能系统的全部潜力。我们将开发一种无CRM技术，该技术具有类似电池的能量密度（>20 Wh/kg，>16 Wh/L），以及传统电化学双层电容器独特的上级功率密度和高循环寿命。GREENCAP将利用层状2D材料，包括石墨烯和MXenes作为电极材料，以及离子液体（IL）作为高压电解质。GREENCAP的主要目标是：i）通过简单，可扩展和可持续的方法合成/功能化石墨烯和MXenes（无CRM）方法，确保高表面积和离子可及性，引入法拉第电荷存储机制，并改善它们的量子电容; ii）制备具有高电导率和高电化学/热稳定性新型无毒/低毒和不易燃/低易燃IL基电解质，确保SC在-50 ° C至+100 °C的温度范围内在> 3.5 V的电压下运行，从而无需复杂的冷却系统; iii）通过制造TRL 6的圆柱形电池，在工业规模上验证新型SC技术，同时确保从材料到电池生产商的完整价值链的创建/存在; iv）生产一种新型的超级电容器管理系统，使GREECAP的SC在高端应用中发挥全部潜力，并确保其融入循环经济。
