| Synthesis and modification of eco-FR-Oxygraphene to optimize the properties of next-generation advanced anode materials for safe and sustainable Li-ion batteries design | |
| Program: | SRDA |
| Project leader: | Ing. Csík Dávid, PhD. |
| Annotation: | Project SMEBAT addresses the limited access to critical raw materials and performance challenges in lithium-ion batteries (LIBs) by developing advanced anode material, FR-Oxygraphene. Emphasizing sustainability, the project uses green chemistry and low-temperature oxidative catalytic pyrolysis to synthesize FR-Oxygraphene from ecofriendly materials like cotton fibers, paper cellulose, and waste textiles, minimizing environmental impact. FROxygraphene, with a multilayer tubular structure, shows significant potential as an anode material. Its high specific surface area, excellent electrical conductivity, and large pore volume offer advantages over conventional graphite anodes. To improve electrochemical performance, heteroatoms like silicon will be incorporated into the material to overcome issues associated with conventional anodes, such as low capacity, low cycle stability, and limited conductivity. Optimizing this functionalization is crucial for maximizing FR-Oxygraphene\’s potential, leading to superior LIB performance. Project SMEBAT also focuses on battery cell design and validation. Laboratory-scale prototypes of Li-ion battery cells will be designed and fabricated to test FR-Oxygraphene anodes. Comprehensive electrochemical evaluations will compare FR-Oxygraphene to conventional graphite anodes, aiming to demonstrate superior capacity, charge-discharge rates, and cycle stability. The project aims to reach TRL5 by verifying the technology in an industrial environment, preparing modified FR-Oxygraphene as a suitable advanced anode material for LIBs. SMEBAT envisions developing LIBs that are powerful, environmentally friendly, and sustainable. By utilizing FR-Oxygraphene\’s unique properties, SMEBAT aims to create LIBs with higher energy density, faster charge-discharge rates, and longer cycle life, while reducing environmental impact. This aligns with regional, national, and European initiatives for sustainable energy storage solutions. |

| Development of New Efficient Alloys for Hydrogen Storage | |
| Program: | VEGA |
| Project leader: | Mgr. Oroszová Lenka, PhD. |
| Annotation: | The project focuses on the development and research of medium and high entropy alloys for hydrogen storage. Currently, the most efficient and safest way to store H2 is its chemical bonding in the metal alloys lattices to form metal hydrides. The problem with current alloys is the too high temperature (exceeding 400 °C) at which H2 is released from their volume. The latest trend in material development in this area is towards microalloying of high entropy alloys with elements that can significantly reduce the desorption temperature of H2 from their volume. The amount of stored hydrogen can also be increased by plastic deformation of the matrix. Both of these approaches are the subject of this scientific project. Our main goal is to develop materials with high absorption capacity (> 2 wt.%), low desorption temperature < 140 °C and high cyclic absorption/desorption stability (> 1000 cycles with a capacity decrease of less than10%). |
