How can we make iron-based flow batteries even more cost-effective, durable, and reliable for long-term use? I’m thrilled to share our latest research, published in Advanced Energy Materials as front inside cover (https://lnkd.in/gSSYv3KY)! Our study, “Strategically Modified Ligand Incorporating Mixed Phosphonate and Carboxylate Groups to Enhance Performance in All-Iron Redox Flow Batteries,” focuses on pushing the boundaries of sustainable energy storage. By designing a novel iron complex with a mixed phosphonate/carboxylate ligand (BPMG), we achieved higher battery output voltage compared to our previous design, a phosphonate ligand (NTMPA), published in Nature Communication (https://lnkd.in/gpV9rwwN) earlier this year. The results show hundreds of stable charge/discharge cycles, nearly zero capacity degradation, and 100% Coulombic efficiency under near-neutral pH conditions. Key insights from this work include: ·        Advanced ligand design to improve redox kinetics and structural stability. ·        Density functional theory (DFT) and operando spectroscopy revealing the mechanism behind enhanced performance. ·        A cost-effective and scalable pathway for stationary energy storage, utilizing abundant materials like iron. This work would not have been possible without the dedication of incredible team work: Gabriel S. Nambafu and Aaron M. Hollas, who turned innovative designs and concepts into real experimental results; Peter S. Rice, Jon Mark Weller, and Daria Boglaienko, for thorough DFT calculations and comprehensive spectroscopic characterizations; and David M. Reed and Vincent L. Sprenkle, for their invaluable management support. A huge thank you to our collaborators and the U.S. Department of Energy, Office of Electricity, for the support in making this effort a real! Together, we're advancing the future of renewable energy integration. #EnergyStorage #RedoxFlowBattery #Complex #Sustainability #Lowcost

Swiss energy storage pioneer Leclanché SA has unveiled the XN50, the world’s first lithium-ion battery cell featuring a niobium-based active anode material. This groundbreaking innovation outperforms current battery chemistries, especially in heavy-duty e-mobility, rail, and marine applications. “We are absolutely delighted to announce the launch of the world’s first commercial XNO Li-ion cell,” said Pierre Blanc, CEO of Leclanché SA. The XN50 will replace the current LTO battery solution and complement the existing G/NMC offering as the go-to fast charging battery solution for heavy-duty applications. The XN50, featuring Echion Technologies’ XNO, boasts a 50% better energy density than LTO tech and supports quick charging. It delivers superior performance and exceptional safety, even in harsh conditions, with a projected lifespan of over 10,000 cycles. This innovation sets a new standard for heavy-duty Li-ion batteries and is poised to transform energy storage with state-of-the-art technology, offering a robust and sustainable substitute for conventional battery solutions. #EnergyStorage #Innovation #Sustainability #Leclanché #NiobiumIon #EchionTechnologies #BatteryTechnology #HeavyDutyApplications #XN50

🔋 #BatteryTechmology Updates: Gelion achieves 402 Wh/kg energy density in its GEN 3 #LithiumSulfur (Li-S) #battery, surpassing current lithium-ion technology and marking a significant milestone in lightweight, high-energy storage solutions. — https://lnkd.in/e-wGAmMc #batterytech #batteryresearch #lithiumionbattery

🚀 Major Milestone for #TeamGelion! We are thrilled to announce the successful fabrication of our Next-Gen ("GEN 3") Lithium Sulfur semi-solid-state cell, achieving an impressive energy density of 402 Wh/kg. This advancement marks a significant leap, with our GEN 3 Li-S cell being over 60% lighter than a typical lithium-ion battery / delivering an energy density 60-70% higher than current lithium-ion technologies (approximately 200-250 Wh/kg). Gelion’s GEN 3 Li-S technology stands out by: ✔️ Eliminating reactive additives ✔️ Utilizing a cathode made from commercially available materials ✔️ Being fabricated through a water-based (non-toxic) low-energy self-assembly process at room temperature, fully adaptable to existing gigafactory manufacturing equipment

Gelion's GEN 3 Lithium-Sulfur delivers energy density above 400Wh/kg. As predicted in the announcement on 15 August 2024, Gelion has now successfully achieved the energy density milestone of 402 Wh/Kg in a 12 Ah cell comprised of its GEN 3 semi-solid-state Li-S technology. The achieved energy density is 60-70% higher than current #lithiumion batteries (approximately 200-250 Wh/kg), meaning a single Gelion GEN 3 Li-S cell is over 60% lighter than a typical lithium-ion battery of the same energy.  Head to the link below to read the full announcement on our website. #lithiumsulfur #geliontechnologies

🔋 #Batteries are expected to play a critical role in stationary energy storage systems (ESSs), such as the storage of excess energy produced using #solar and #wind in order to deliver consistent and predictable power for direct use or feeding into the grid. 💡 Although battery technologies have been advancing steadily in the last years, there are additional step changes need to be made in: 1. Improved specific energy and energy density (more energy stored per volume / weight) 2. Longer lifetime 3. Charging duration 4. Reduced levelized cost of energy 5. Better safety ❓How can we achieve these 👉 Through a significant leap in design 👉 Selecting the right material of construction for battery parts - due to volume needs and material security challenges along with the drive to meet sustainability targets, #biomass derived materials, such as #lignin is one of the most promising and suitable starting material for battery components. Lixea's innovative, #ionic liquid-based biorefinery process delivers a unique, highly pure #lignin that has the potential to disrupt the energy storage space.
