Scientists at the Institute of Nano Science and Technology (INST), Mohali, have devised an innovative laser-based technique to improve the performance of Metal Organic Framework (MOF)-based supercapacitors.
By precisely controlling defects and porosity in the material, this method could significantly enhance energy storage capabilities.
The new approach surpasses traditional methods like thermal annealing, chemical exposure, and ball milling, which often lack precision in defect creation.
Led by Prof. Vivek Bagchi, the research team utilized laser irradiation on CuZn-BTC MOF, allowing them to increase the electrode's surface area without disturbing the crystal structure of the MOF. The study, published in ACS Materials Letters, demonstrates how careful adjustment of laser power improves ion diffusion, boosting the material’s energy storage efficiency.
Unlike conventional methods that can degrade the MOF or transform it into composites, this laser technique maintains the crystallinity of the original structure while enhancing its electrochemical properties.
By selectively breaking certain bonds, the laser creates pores that facilitate better ion travel without altering the overall framework.
Beyond performance, this laser method also offers environmental benefits. It eliminates the need for chemical solvents, making it a cleaner, faster, and safer process for enhancing energy storage devices. The findings suggest this laser technique could be applied to other MOF materials, potentially advancing energy storage technologies in the future.
