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 found that sulfate ions reduce free water in aqueous batteries, mitigating parasitic reactions that degrade the anode and shorten battery life. Adding zinc sulfate increased battery lifespan by more than ten times. Sulfate salts stabilize the bonds of free water, acting as a "water glue" to reduce parasitic reactions. Why it matters: This finding provides a cheap and scalable approach to improve the viability of aqueous batteries for sustainable energy storage, particularly for integrating renewable energy sources.
KAUST's Center of Excellence for Renewable Energy and Storage Technologies (CREST) hosted a seminar on rechargeable hydrogen gas batteries. Professor Wei Chen from the University of Science and Technology of China (USTC) presented the seminar. The talk covered aqueous nickel-hydrogen gas, proton-hydrogen gas, halogen-hydrogen gas, and nonaqueous lithium-hydrogen gas batteries, along with applications like self-charging batteries. Why it matters: Hydrogen gas batteries represent a promising avenue for large-scale energy storage, particularly for integrating renewable energy sources into electric grids.
KAUST researchers have made several advances, including a new computational model of the Red Sea's ocean circulation. They also synthesized new metal-organic frameworks for gas storage with applications in green and medical tech. Additionally, they presented a mathematical solution for microgrid cybersecurity. Why it matters: These diverse research projects highlight KAUST's contributions to environmental modeling, materials science, and critical infrastructure protection in the region.
KAUST researchers have developed a saliva-powered microbial fuel cell (MFC) that generates electricity using electrogenic bacteria to consume waste and release electrons. The micro-MFC uses graphene as an anode and an air cathode, achieving high current densities (1190 A m-3). The MFC produced 40 times more power than through the use of a carbon cloth anode. Why it matters: This technology offers a novel way to power lab-on-chip or portable diagnostic devices, particularly in remote or dangerous areas, and may offer alternatives to energy-intensive water purification technologies.
Professor Enrico Traversa from KAUST has been selected to feature in the inaugural Electrochemical Society's (ECS) Trading Card Series, to be introduced at the 227th ECS Meeting in Chicago. Traversa, a Principal Investigator at KAUST's Materials for Energy Conversion and Storage Lab, is recognized for his contributions to electrochemical and solid-state science. The trading cards will include a biography and statistics on patents, research papers, and ECS awards. Why it matters: This recognition highlights KAUST's contributions to the field of electrochemical science and acknowledges the impact of its researchers on a global scale.
KAUST researchers, in collaboration with KACST, discovered that dissolving nylon in battery electrolytes improves the performance of lithium-metal batteries. The nylon additive resulted in more efficient batteries with longer lifespans and fewer unwanted reactions. The research was published in ACS Energy Letters and Energy Environmental Science. Why it matters: This promises cheaper, safer, and more powerful lithium batteries for applications in electric vehicles and aviation, supporting Saudi Arabia's renewable energy goals.
