PHyS-2D-GraM

Project Info

Recent tremendous advances in portable and wearable electronics demand lean, lightweight and flexible future energy-storage devices. PHyS-2D-GraM stands for ‘Printable Hybrid Micro-Supercapacitor Based on 2-D Inks using Graphene, TMDs and M-Xenes’ and is mainly focused on printable, flexible and portable energy-storage devices based on 2-dimensional (2D) materials and their nanocomposites. The attraction of PHyS-2D-GraM is excellent electrical conductivity and large-scale low-cost production capability, as well as the environmentally benign properties of the hybrid 2D materials. This will facilitate the achievement of micro-supercapacitors with high power and energy densities, to successfully replace batteries used in smart garments.

The main objective is to demonstrate and fabricate printable, flexible micro-supercapacitors from hybrid 2D nanocomposite designs of vertically stacked current collectors, electrodes and electrolytes aimed at higher specific energy (>10 Wh kg-1) by controlled multiple-pass printing with porous microstructure in interface layers. Growth in the energy-storage market will be mainly driven by the demand for smart, connected, energy-efficient, flexible devices, along with the advantage that methods of manufacture are low-cost for printed devices.

Research studies in realising hybrid MXeneTMD-Graphene inks for flexible micro-supercapacitor are very limited, but have kindled significant interest and are the foundation of the PHyS-2D-GraM project. All the key components of micro-supercapacitors, namely, electrodes, electrolytes and current collectors, can be fabricated by Inkjet Printing through proper formulation and deposition of 2D hybrid inks.
