KAUST and Aramco are partnering to develop extreme temperature-resilient batteries for subsurface applications and the hot climate of Saudi Arabia. The new batteries aim to operate effectively from subzero to 130°C, addressing the limitations of traditional lithium-based batteries that degrade above 60°C. KAUST is focusing on identifying electrolytes and separators that can endure high temperatures, while Aramco provides operational expertise. Why it matters: This collaboration could lead to significant cost savings in the energy sector, improve battery performance in EVs and grid systems, and position Saudi Arabia as a leader in advanced battery technology for extreme environments.
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.
KAUST researchers have developed a new technology for direct lithium extraction from brine in oilfields and seawater, potentially positioning Saudi Arabia as a major lithium producer. The technology, demonstrated at a pilot scale, allows extraction from low-concentration sources (as low as 20 parts per million) without pollutants. It could increase global lithium resources from 22 million tons to over 230 billion tons. Why it matters: This innovation could transform Saudi Arabia from a lithium importer to a producer, strengthening its energy security and influence in the global clean energy market.
Aramco and KAUST-incubated startup Lihytech are collaborating to develop Direct Lithium Extraction (DLE) technology in Saudi Arabia. Aramco is providing oilfield brines to Lihytech to assess their lithium extraction technology at KAUST Research and Technology Park. The collaboration supports Saudi Arabia's Vision 2030 and its growing demand for lithium in electric vehicles. Why it matters: This partnership could unlock a new critical mineral industry in Saudi Arabia, leveraging existing oilfield resources for sustainable lithium production.
KAUST startup Lihytech has raised US$6 million in funding from Ma'aden and the KAUST Innovation Ventures Fund. Lihytech's patented membrane technology, developed by Professor Zhiping Lai at KAUST, extracts battery-grade lithium from sources like seawater. The funding will be used to build a pilot facility at KAUST to extract lithium from the Red Sea and other in-Kingdom resources. Why it matters: This investment supports Saudi Arabia's goal of developing a complete electric vehicle value chain and becoming a key player in meeting global lithium demand.
KAUST researchers reported the full genome sequencing of einkorn wheat in Nature. A new 'cooling score' metric was created to study heat's impact on solar cell performance. KAUST is also optimizing MXenes for lithium batteries and using biomimetic mineralization for smart agriculture. Why it matters: This research demonstrates KAUST's contributions to diverse fields, including genomics, sustainable energy, and smart agriculture, advancing technological innovation in Saudi Arabia.
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 Discovery will host a webinar on solvent-based recycling of lithium-ion batteries. The presentation will be given by Dr. Yaocai Bai, an R&D Staff Scientist at Oak Ridge National Laboratory (ORNL). The talk will explore solvent-based separation processes to efficiently separate electrode materials from metal foils in end-of-life batteries and manufacturing scraps. Why it matters: Battery recycling is a key area for sustainability efforts in the region, as it has implications for energy independence and environmental protection.
