The EU project GREENCAP will realize a novel type of sustainable and high-energy density supercapacitors, which exploit layered 2D materials, including graphene and MXenes as electrode materials, and ionic liquids as high-voltage electrolyte.
Design, production, and upscaling of novel CRM-free and sustainable 2D electrode materials for supercapacitors.
Formulation of novel CRM-free electrolytes based on ionic liquids (ILs) and mixtures of ILs and organic solvents for supercapacitors.
Fabrication and characterization of sustainable 2D material- and IL-based supercapacitors beyond state-of-the-art electrochemical double-layer capacitors and with battery-like characteristics.
Creation of innovative SoX monitoring tools (SoX denotes the state of health -SoH-, state of charge -SoC, state of energy -SoE-, state of power -SoP-, and state of safety -SoS-) and management system for layered two-dimensional (2D) materials and ionic liquids-based supercapacitors.
Identification of new high-end applications based on comprehensive impact assessment of social, environmental, and economic sustainability.
GREENCAP will design, develop, and prototype in industrial lines high-performance and sustainable layered two-dimensional (2D) materials and ionic liquids-based cylindrical supercapacitors with their own management system that 1) exhibit a battery-like energy density (i.e., >20 Wh/kg, >16 Wh/L), 2) retain the distinctive superior power densities (>1000 W/kg, >500 W/L) and high cycle life (>1000000 charge/discharge cycles) of traditional SCs, i.e., electrochemical double layer capacitors, 3) eliminate the use of CRMs, aiming at reaching TRL 6.
GREENCAP will realize a novel type of sustainable and high-energy density supercapacitors, establishing an entire device manufacturing chain, which considers:
- scalability and sustainability of novel CRM-free 2D electrode materials and ionic liquid-based electrolytes, produced at industrial scale through eco-friendly processes by means of CRM-free materials, while guaranteeing reproducible characteristics.
- synergic coupling between layered 2D materials and IL-based electrolytes, whose interaction results in electrochemical charge storage mechanisms leading to high electrode performances in terms of capacitance/capacity and CD cycling stability.
- scalability and sustainability of electrode fabrication and SC assembly, which must be therefore feasible in industrial SC manufacturing lines.
The GREENCAP workplan is divided into 4 research-related work packages (WPs), one WP for impact assessment and benchmarking and 2 management and dissemination-related WPs.
The results of the GREENCAP project are documented in reports. As soon as the reports are available they will be published here.
