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 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.
KAUST hosted the Frontiers in Energy Storage 2026 conference, emphasizing energy storage technologies for renewable energy. The conference highlighted electrochemical and chemical systems, including advanced batteries and hydrogen, as complementary layers for long-duration and industrial resilience. KAUST is developing energy-storage solutions relevant for the Kingdom and valuable to global partners, aiming to engineer solutions to withstand extreme environmental temperatures. Why it matters: This positions Saudi Arabia as a potential global exporter of resilient energy hardware, aligning with Saudi Vision 2030 goals in renewable energy.
KAUST researchers have developed a tin oxide (SnO2) Li-ion battery anode coated with hafnium oxide (HfO2) using atomic layer deposition. The HfO2 coating reduces volume changes in the SnO2 anode during charging and discharging, improving storage capacity by 56% and cycling stability. The technique is insensitive to HfO2 thickness, attributed to the amorphous structure and catalytic effect of hafnium. Why it matters: This research offers a promising approach to enhance Li-ion battery performance, which is crucial for advancing energy storage technologies in the region and globally.
KAUST researchers have integrated a hexagonal boron nitride sheet into CMOS microchips, creating a hybrid 2D-CMOS microchip.
