JNCASR partners with HZL to scale up indigenous Zn-ion battery technologies Indigenous Zn-ion battery technologies with new variant of zinc materials could soon facilitate low-cost grid-scale energy storage and other related applications. Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR), an autonomous institute of the Department of Science and Technology (DST) has signed a Memorandum of Understanding (MoU) with Hindustan Zinc Limited (HZL), to develop new variants of zinc materials & propel the commercialization of zinc-based batteries. Low-cost and superior performance driven zinc-ion batteries are acclaimed as India’s innovative alternative to expensive and imported lithium-ion batteries. Zinc-ion batteries hold enormous potential for large-scale energy storage due to low-cost and Earth abundant raw materials. However, their commercialization is dependent on stabilizing the material’s performance. For instance, zinc is thermodynamically unstable with water-based solutions and therefore requires suitable modifications at the electrode, electrolyte and interfaces. Addressing these issues, the partnership is poised to drive material innovation and accelerate the development of indigenous Zn-ion battery technologies. Prof. Premkumar Senguttuvan’s group at JNCASR has built a robust research foundation in zinc-based batteries. The group's state-of-the-art battery characterization facility, funded by the Department of Science and Technology has led to significant advancements in the field. The resulting research has produced significant publications which have attracted the interest of leading industry players like Hindustan Zinc in the zinc sector. Prof. Senguttuvan plans to modulate the structure and chemical compositions of alloys and electrolytes from atomic/molecular to device level to evolve the existing issues with materials.A modified electrolyte is expected to increase the life and safety of devices. The JNCASR team also plans to demonstrate Zn-ion pouch batteries which is easily scalable for large-scale commercial applications. By providing innovative new product solutions, Hindustan Zinc aims to be at the forefront of the battery revolution to support the ongoing global energy transition. The research agreement targets two major Sustainability Development Goals SDG7 (Affordable and Clean Energy) and SDG13 (Climate Action) – ensuring access to affordable,reliable,sustainable and modern energy for all and taking urgent action to combat climate change and its impact,marking a pivotalmoment in the evolution of battery technologies.

Scaling up organic photovoltaics (OPVs) for large-scale manufacturing requires cost-effective and efficient fabrication methods. This study investigates the application of solution-processed tungsten trioxide (WO3) nanoparticles as a hole transport layer (HTL) in inverted OPVs, specifically focusing on scalability through different deposition techniques.

*****New Publication Alert ***** New paper in American Chemical Society’s #ACSEnergyLetters journal. “Electrolyte Intermolecular Interaction Mediated Nonflammable Potassium-Ion Sulfur Batteries” The design of electrolytes that are compatible with graphite electrodes and incorporate flame-retardant properties in potassium-ion batteries (PIBs) can not only facilitate their commercialization but also improve the safety reliability. However, it remains challenging, particularly in propylene carbonate (PC)-based electrolytes. Herein, we achieved a highly reversible K (de)intercalation with graphite in PC-based electrolytes by introducing the fluoroethers. We identified the strength of interactions formed between fluoroethers (e.g., 1,1,2,2-tetrafluoroethy-2,2,3,3-tetrafluoropropyl ether (HFE), 1,1,2,2-tetrafluoroethyl 2,2,2-trifluoroethyl ether (TFTFE)) and PC by heteronuclear overhauser effect spectroscopy. We find that the interaction between HFE and PC is stronger, which can significantly weaken the K -PC interaction, contributing to a reversible K (de)intercalation and also endowing electrolyte nonflammable features. The kinetic and thermodynamic properties of K -solvent-anion complexes in the proposed interfacial model can elucidate the electrolyte and electrode stability, enabling the as-designed potassium-ion sulfur batteries to show high performance. This discovery offers a fresh perspective for designing and advancing electrolytes in PIBs and beyond. https://lnkd.in/gEiQyUgN Stay tuned for more exciting news from the School of Physical Sciences at Jawaharlal Nehru University, New Delhi, India. #JNU, #SPS #SPSJNU #KIonBattery #Cathode #Anode #PotasiumSulfur #Electrolyte #nonflamableelectrolyte #graphiteanode #SPANCathode #ElectrolyteAdditives #ElectrolyteMicrostructures #KSBatteries #InterMolecularInteraction #PotasiumSulfurBatteries #EnergyStorage #Batteries #ElectrolyteSolvationChemistry #InterfacialModel #ACS #AmericanChemicalSociety #ACSEnergyLetters Jawaharlal Nehru University (JNU) Dr. Prashant Tripathi Avinash Rundla Divya Rani Raghuvanshi Shivani Singh Rajkamal Arya Manjusha Shelke

"A recent BloombergNEF study recognizes several emerging battery technologies that are more suited to supporting #LDES use cases, including some that are already cost-competitive with Li-ion (or better). In particular, metal-hydrogen battery technology differentiates itself from Li-ion and shows its high potential as an LDES option by providing flexible dispatch at 10–12-hour durations, along with stronger overcharge and discharge characteristics. The ability to use 100% of the battery’s capacity allows for steady power output over extended periods."

NREL team evaluates sustainability pathways for perovskite photovoltaics. Researchers at NREL have examined how metal halide perovskite photovoltaics (MHP-PV) could scale a sustainable supply chain while appreciably contributing to a global renewable energy transition. They evaluated the critical material concerns, embodied energy, carbon impacts and circular supply chain processes of MHP-PVs. https://lnkd.in/dVP3sZfk #perovskite National Renewable Energy Laboratory
