⚡🔬Challenging the established using of LiAlO2 in molten carbonate fuel cells (MCFCs) for over half a century is no easy feat, but here is our attempt! Our latest research explores new solid electrolyte support matrix materials, specifically perovskite oxide ion conductors BNT and LNT. Our findings show that LNT offers superior stability and higher power output density compared to traditional LiAlO2. https://lnkd.in/dxb_CsQh Thanks to EEA and Norway Grants NOR/POLNOR/MOLCAR/0017/2020-00

Very happy to share that my first scientific article has been published in the International Journal of Hydrogen Energy. The article shows how the alternation of a processing step changes the electrochemistry and durability of the anode of a PEM fuel cell. The findings are not limited to the PEM fuel cell, but might also be of interest for processing of PEM electrolysers. Many thanks to all the co-authors (Adrian Jurjević, Dr. Matteo Scolari, Atsushi Urakawa, Peyman Taheri) and especially to Dr. Kerem Aylar for introducing me to the scientific world of PEMFC processing and the reversal tolerant anode. https://lnkd.in/eJFjUUFQ

Researchers have improved the performance of proton exchange membrane water electrolysis (PEMWE) by creating electron and proton pathways using a hybrid conductor, PEDOT:F ionomer. This material, when combined with perfluorinated sulfonic acid (PFSA), enhances the catalytic activity and stability of the anode catalyst layer, facilitating better conductivity and reducing energy barriers. The resulting structure allows for more efficient water adsorption and electrochemical reactions, significantly enhancing the efficiency and performance of PEMWE compared to traditional Nafion-based systems.

Exciting advancements in lithium-sulfur (Li-S) battery technology are on the horizon, as highlighted in our recently published paper in #RSC #MaterialsHorizon (https://lnkd.in/gej_4i-Z) The study focuses on enhancing Li-S battery efficiency through the utilization of a novel 2D/2D g-C3N4@MXene heterostructure. This innovative approach not only improves sulfur evolution reactions but also effectively regulates polysulfides, crucially addressing challenges in lean electrolyte conditions. Such developments are pivotal in the quest for sustainable energy solutions, promising greater energy density, longer-lasting batteries, and reduced environmental impact. This research represents a significant step forward in the evolution of Li-S batteries, highlighting the ongoing commitment to pushing the boundaries of energy storage technologies.

Excited to share with you our (Dr. Vijay K. Tomer, Otávio Augusto Titton Dias, myself and Ritu Malik) recent work about Advancing Lithium-Sulfur Battery Efficiency. In this work, We utilize a novel 2D Ti3C2 Mxene on a 2D g-C3N4 heterostructure designed to enhance LiPS conversion kinetics and adsorption capacity. In pouch cell configuration, the g-C3N4-Mx/S cathode exhibited excellent rate performance, delivering ~1061 mAh/g at C/8 and retaining ~773 mAh/g after 190 cycles with a Coulombic efficiency of 90.4%. The battery maintained a discharge capacity of 680 mAh/g even at 1.25 C. It operated at an elevated sulfur loading of 5.9 mg/cm2, with an initial discharge capacity of ~900 mAh/g and a sustained CE of over 83% throughout 190 cycles. https://lnkd.in/g_BMdCfK

Ni-rich NCM-based cathodes with Ni-contents even above 90% can relevantly improve the specific energy/energy density of Li ion batteries, but suffer from a pronounced capacity fade, reaching the set state-of-health (SOH) <200 charge/discharge cycles. The literature-known modification with tungsten (W) can be an effective solution. In this work, Marcel Heidbüchel incorporated W already on the hydroxide-based precursor, which enables water as processing solvent and can crucially affect/control the primary particle shape of final NCM-based cathode active material. The overall cycle life can be prolonged to > 500 cycles, see: https://lnkd.in/gY6iH_pS Thanks for this work also to Aurora Gomez Martin, Lars Frankenstein, Ardavan Makvandi, Martin Peterlechner, Gerhrd Wilde and Martin Winter from Universität Münster and MEET Battery Research Center, funded by European Union within SeNSE Battery project. #battery #lithium #NCM #synthesis #Nirich #coating
