We are developing Metal-Organochalcogenide (M-OrC) batteries, which synergistically combine a redox-functionalized organic backbone with covalently linked organo-chalcogenide (sulfide/selenide) bridges. This hybrid framework is designed to enhance redox activity per unit mass, paving the way for higher specific capacities and energy densities. The key challenge, however, lies in aligning the operating potential windows of the redox-active organic segments and the organo-chalcogenide bridges to ensure efficient charge transfer and utilization.

We are developing eco-friendly Organic Green Batteries using fully organic materials for sustainable energy storage. The battery features a P-type organic polymer cathode and an N-type polymer anode, enabling efficient redox reactions without toxic metals. An ionic liquid electrolyte with an enlarged electrochemical window ensures high energy density, safety, and thermal stability. All components are derived from renewable sources and are recyclable or biodegradable. Our low-energy fabrication process further reduces environmental impact. Designed for green electronics and off-grid systems, this battery represents a clean, circular, and scalable alternative to conventional lithium-ion technology.

We are developing a photo-rechargeable Li-ion battery that integrates a photocathode capable of generating current upon light (photon) excitation, storing energy by driving electrons to the negative electrode and lithium ions to the positive one. Designing such photocathodes is challenging due to difficulties in bandgap tuning, sluggish charge transport, and poor photo-stability. Moreover, combining light harvesting with charge storage via redox or ion intercalation is rare. By using reticular organic materials, we aim to precisely engineer energy levels and spatially separate electron/hole pathways to enhance light absorption, charge transport, and minimize recombination losses.

We are engineering Ionologic, a novel technique that uses ion electro-adsorption in unified pores to implement capacitive logic gates, mimicking electronic circuits and biological systems. This approach offers high-density, low-power potential for ion-based computing. However, challenges in creating electrodes for ionologic gates include limited ion adsorption, ion diffusion issues, and electrolyte compatibility. By utilizing reticular organic frameworks (e.g., Graphyne, COF, g-C3N4), with engineered pores and surface functionalities, we are enhancing selective ion percolation, ion polarization, and diffusion, enabling faster responses for more efficient ion-based computing.

We develop high-performance carbon-based electrode materials by valorizing agro-waste such as sugarcane bagasse, spent coffee grounds, and peanut shells. These biomass sources are rich in lignocellulosic content, making them ideal carbon precursors. Our strategy involves using a tailored organic soft-templating method to induce porosity in the derived carbon structures. This process allows us to precisely balance conductivity and porosity, which is crucial for optimizing charge storage performance. The resulting porous carbon materials exhibit excellent electrical conductivity, high surface area, and tunable pore structures—making them ideal candidates for coating as electrode materials in metal-ion batteries. Our method offers a sustainable and scalable route to produce advanced functional carbons, directly contributing to green energy solutions and circular economy goals.
