Metal-base Electroactive Materials for Energy Storage

Our research on batteries focuses on key innovations, including advanced cathode materials for sodium ion batteries (SIB), novel electrolytes, and creative reuse of materials recycled from lithium batteries. A major area of interest is metal compound-based hybrid electrochemical energy storage (HEES), a promising approach that balances high energy storage capacity with superior power performance.

The efficiency of metal-based redox electrodes is dictated by their chemical composition, morphology, crystal structure, and conductivity. In the framework of international and national projects, we develop customized electrode materials by combining synergistic mixtures of Ni, Co, Fe, and Mn compounds. These materials, integrated with carbon-based components (including graphene) and functionalized metallic nanofoams, are specifically tailored for enhanced electrochemical activity in aqueous electrolytes, thereby optimizing performance for targeted applications, including the production of green hydrogen from water splitting.

This research has led to the creation of our spin-off company C2CNewCap and fosters strong collaborations with industry and international partners. 

Advancing Bio-Based Electroactive Materials

In alignment with sustainability goals, we are actively exploring bio-based electroactive material supported on natural bio-metal interactions, a rapidly growing field essential for ensuring a smooth and eco-conscious energy transition. Our research focuses on plant-derived and waste-sourced materials for energy storage applications, including bio-inspired redox-active compounds and carbon materials derived from renewable sources. By integrating these sustainable alternatives into supercapacitors and battery electrodes, we aim to develop high-performance, environmentally friendly energy storage solutions that reduce reliance on critical raw materials while enhancing circularity in energy technologies.
