{"title": ["", "Practical Lithium Air Batteries"], "description": ["", "\nThis project is centred around the development of a practical lithium air battery single cell with improved performance. The\nproject consortium includes Queens University Belfast and Liverpool University as academic partners and Johnson\nMatthey, Axeon, JLR and Air Products as the industrial partners.\nThe instability of existing electrolytes to superoxides is a major barrier to achieving good cycle life in current laboratory\nscale Li-air cells, due to capacity fade as a result of the formation of irreversible species from solvent decomposition that\noccurs if current Lithium ion battery organic electrolytes are used. Therefore, significant effort will focus on synthesising\nnovel electrolytes capable of surviving operation in Li-air batteries, where a large operational voltage window and immunity\nto degradation from superoxide attack are key features, combined with practical levels of oxygen solubility and ionic\nconductivity. Novel ionic liquid electrolytes and blends will be synthesised using the expertise at QUB and also drawing on\nempirical and modelling results already available in the literature, relating to solvent stability in the presence of superoxide.\nNovel anode and cathode materials and catalysts will be prepared and tested (JM) in combination with improved\nelectrolytes synthesised in the project (JM). Emphasis will also be placed on optimising cathode structures for the novel\nelectrolytes to achieve improved capacity, current density and cycle life (JM, Axeon). Understanding the cathode reactions\noxygen reduction during discharge and oxygen evolution during charge with new electrolytes via iR and Raman\nspectroelectrochemistry techniques will be undertaken (Liverpool University) and the behaviour at the anode interface in\nthe novel electrolytes will also be explored. The wide variety of analytical techniques available via the different project\npartners including XPS, ATR, electron microscopy and electrochemical measurements will be applied within the project.\nCell testing studies will investigating the effects of various parameters, pressure, temperature , charge rate, the effect of\ncarbon dioxide and water impurities in inlet air and possible inlet air clean up strategies also be considered (JM, Axeon, Air\nProducts, JLR).\nThe key outputs from the project will be an optimised single cell configuration with the best electrolyte, electrode material\nand electrode structure combination, accompanied by understanding of the electrochemistry and the effect of cathode\nstructure and test parameters on battery performance and cyclability. These data contribute toward establishing the\nfeasibility of lithium air battery technology and will lay a firm foundation for future development of larger scale\ndemonstration systems .\n\n"], "extra_text": ["", "\n\nPotential Impact:\nThe successful development of a novel electrolyte for Lithium air batteries and associated understanding gained within this\nproject will be a significant enabler for future industrial research, product development and ultimately the viability of lithium\nair battery systems for larger scale use. This will benefit the project partners, their associates and stakeholders in the wider\nbattery supply chain growing within the UK.\nThis project is targeted at developing energy materials for advanced battery systems with energy densities > 400Wh/kg\nexceeding Li-ion technology and aimed at automotive applications. Predictions (by LMC Automotive) imply the number of\nvehicles that contain an element of electrification within their drive train is estimated to increase from 1.5% of the market to 8% by the end of the decade. Further expansion is prohibited by the cost and the performance of the battery packs. Lithium\nair batteries have a substantially higher theoretical energy density than Lithium ion, such that a 3-5 times battery capacity\nbenefit in practical systems is still predicted for Lithium air, even when factors such as additional weight of cell components\nand single cell to pack efficiency losses are taken into account. Thus such batteries might provide greater range/lower cost\nin automotive systems. However, electrolyte instability and associated poor cyclability of these batteries remains a\nsignificant barrier to success. Improvements to electrode materials/structure and a full understanding of the requirements\nfor a Lithium air battery system (air purification and on paper system feasibility investigation) will also be generated, leading\nto associated scale up work within the UK in the future, for materials, electrodes, battery packs and ultimately systems.\nInformation on the novel materials, cell testing and system feasibility generated will be disseminated via conferences,\npublications as appropriate. The project also provides training via PhD projects and application of existing expertise in new\nareas via the academic and industrial project work. Research is increasing worldwide on metal air and advanced battery\nmaterials topics, especially in Asia and the USA and this project will accelerate the progress of research on these topics in\nthe UK.\nResults from the project also overlap into other technology areas for example, the use of high stability electrolytes in Li-ion\nbatteries and supercapacitors and overlap of air cathode, air purification and system aspects with other metal air battery technologies such as Zn-air.\n\n\n"], "status": ["", "Closed"]}
