Lithium-Ion Batteries

The demand for advanced energy storage technologies is accelerating with the electrification of transportation, the growth of renewable energy, and the need for lightweight, multifunctional power solutions. Lithium-ion batteries (LiBs) dominate high-energy-density applications, while supercapacitors, particularly electric double-layer capacitors (EDLCs), offer superior power delivery and cycling stability. Our research addresses both systems through structural integration and sustainable electrode design.

For LiBs, we aim to develop batteries capable of maintaining structural integrity under severe mechanical and thermal stresses. By embedding active components within composite architectures, we target the integration of power supply directly into structural systems such as unmanned aerial vehicles. One approach involves solid-state Li-ion batteries based on glass-ceramic composites, operating reversibly above 4 V with discharge capacities exceeding 200 mAhg⁻¹ at ~25°C. Another focuses on multifunctional LiBs with tunable mechanical properties, where materials selection and architectural design enable simultaneous improvements in mechanical strength and electrochemical performance.

In parallel, we investigate supercapacitors employing biomass-derived activated carbons as sustainable, high-performance electrodes. Agricultural residues and other biowaste can be converted into porous carbons with tailored surface area, pore structure, and heteroatom functionalities, enhancing capacitance, energy density, and cycling stability. Beyond performance, these materials provide clear economic and environmental benefits by valorizing waste and reducing dependence on synthetic carbons.

Together, our work advances multifunctional, efficient, and sustainable energy storage solutions for next-generation aerospace, automotive, and grid applications.
