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 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 demonstrated a new flash memory device design using gallium oxide, which can withstand harsh environments.
