Supercapacitors (SCs) are promising electrochemical energy storage (EES) systems that can drastically reduce or even eliminate the use of Critical Raw Materials (CRMs) (e.g., Li, Co) compared to current market-dominating technologies, including Li-ion batteries (LiBs). In general, SC does not need any fire protection as it is not susceptible to thermal runaway that can be the cause of dangerous explosion. As a major drawback, the energy density of commercially available SCs is way lower than LIBs. Novel nanostructured electrode materials and their engineering through physical/chemical functionalization incorporating redox-active groups, as well as their hybridization, can substantially improve the energy density of SCs, approaching the values of batteries. Low-dimensional (LD) materials, in particular CNT, graphene and MXene, are promising SC electrode materials. These unique LD structures exhibit a high surface-to-volume ratio coupled with excellent electrical conductivity, electrochemical robustness, mechanical flexibility and high theoretical specific capacitance. Thus, they represent ideal electrode material to overcome the limitations of current SC technologies in terms of energy density. HORNCAP project aims to design, develop, and prototype a pre-industrial SC with battery-like performance using advanced functionalized and hybrid nanomaterials (graphene, MXene and CNT) as electrode materials, and high-safety hybrid electrolyte with wide electrochemical stability window (ESW) and compatible with redox-active electrod materials, promoting market uptaking. The produced pre-industrial cells will target a battery-like energy density of >50 Wh/kg, power density of >100 Wh/kg, and cycling life of >106 cycles. This project aims at reaching a Technological Readiness Level (TRL) 6 by producing the SC cell in an industrial environment.
