D3.1 Synthesis of advanced active materials

The MUSIC project aims to develop a sodium-ion capacitor (SIC), which can provide more power than a conventional lithium-ion battery but at the same time has a higher energy density than a supercapacitor. To achieve that outstanding target, a strong effort is devoted to the development of new active materials and components that show improved performance when integrated in SICs.
As part of D3.1, BYD worked on the synthesis of activated carbons and benchmarking of commercially available activated carbons to be used as positive electrodes for Na-ion hybrid capacitors. CIC focused on the synthesis of advanced hard and soft carbons from different precursors (biowastes, synthetic and recycled polymers) and the surface modifications of commercially available activated carbons to improve both their textural properties and voltage stability window. Simultaneously, JVI and CNRS-IMN focused on the carbon fibers recycled from the aeronautic industry. Further, FSU and ELY developed different electrolyte formulations that outperform the reference electrolytes used for this technology.
