A KAUST team led by Husam Alshareef has developed a microfabricated energy storage device with high energy and power density. The device uses nickel hydroxide as an active electrode material and achieves a volumetric capacitance density of 325 F/cm3. Fabricated using chemical bath deposition at room temperature, the device can power microelectronic devices. Why it matters: This research advances energy storage technology in the region, potentially impacting the development of microelectronics and portable power solutions.
KAUST Professor Husam Alshareef received the Kuwait Prize in Clean and Sustainable Energy Technologies on December 5. The award recognizes Alshareef's contributions to energy storage materials, including sodium and zinc ion batteries and supercapacitors. Alshareef's research group focuses on developing layered electrode materials through various synthesis techniques. Why it matters: The recognition highlights KAUST's growing role in sustainable energy research and the impact of Arab scientists in advancing energy storage technologies.
KAUST researchers used electron tomography and X-ray photoelectron spectroscopy to study charge storage in manganese oxide electrodes for supercapacitors. They found that the electrolyte etches nanoscale openings in the manganese oxide sheets, increasing electrolyte permeability and energy density during cycling. 3D tomography revealed how the electrode's morphological evolution increases its surface area, enhancing energy densities. Why it matters: The research provides insights into improving the cycling stability of pseudocapacitive materials, which are crucial for developing high-performance supercapacitors.
