Das Projekt "Lithium-Air Batteries with split Oxygen Harvesting and Redox processes (LABOHR)" wird vom Umweltbundesamt gefördert und von Universität Münster, Institut für Physikalische Chemie durchgeführt. LABOHR aims to develop Ultra High-Energy battery systems for automotive applications making use of lithium or novel alloy anodes, innovative O2 cathode operating in the liquid phase and a novel system for harvesting O2 from air, which can be regenerated during their operative life without need of disassembling. LABOHR has 5 key objectives: (i) development of a green and safe electrolyte chemistry based on non-volatile, non-flammable ionic liquids (ILs); (ii) use of novel nanostructured high capacity anodes in combination with ionic liquid-based electrolytes; (iii) use of novel 3-D nano-structured O2 cathodes making use of IL-based O2 carriers/electrolytes with the goal to understand and improve the electrode and electrolyte properties and thus their interactions; (iv) development of an innovative device capable of harvesting dry O2 from air; and (v) construction of fully integrated rechargeable lithium-Air cells with optimized electrodes, electrolytes, O2-harvesting system and other ancillaries. Accordingly, LABOHR aims to overcome the energy limitation for the application of the present Li-ion technology in electric vehicles with the goal to: 1- perform frontier research and breakthrough work to position Europe as a leader in the developing field of high energy, environmentally benign and safe batteries and to maintain the leadership in the field of ILs; 2- develop appropriate electrolytes and nano-structured electrodes which combination allows to realize ultra-high energy batteries; 3- develop a battery system concept as well as prototypes of the key components (cell and O2-harvesting device) to verify the feasibility of automotive systems with: A) specific energy and power higher than 500 Wh/kg and 200 W/kg; B) coulombic efficiency higher than 99Prozent during cycling; C) cycle life of 1,000 cycles with 40Prozent maximum loss of capacity, cycling between 90Prozent and 10Prozent SOC; and D) evaluate their integration in electric cars and renewable energy systems.
Das Projekt "Advanced Fluorinated Materials for High Safety, Energy and Calendar Life Lithium Ion Batteries (AMELIE)" wird vom Umweltbundesamt gefördert und von SOLVAY SOLEXIS S.P.A. durchgeführt. The focus of the project is on the development of fluorinated electrolyte/separator and binders in combination with active electrodes (anode LiC6 and cathode: LiNixMn2-xO4 - 4,7V) for high performing, safe and durable Li batteries. The main deliverables of the project are the development of cell prototypes capacity greater than 10 A.h on which performance assessment will be conducted. The AMELIE prototype performances will be assessed towards the following objectives for EV and PHEV applications: high specific energy: cells greater than 200 Wh/kg, improved life time: greater than 1000 cycles, 80Prozent DOD for EV applications, High calendar life: greater than 10 years, high recyclability / recovery/ reuse: battery components 85Prozent recycled and improved competitiveness: less than 500 Euro/kWh on prototype paving the way for mass production cost less than 150 Euro/ kWh. The utilization of higher performing 'inactive' organic materials (polymers and ionomers) will enable to reduce the amount of the same materials while increasing the energy and power densities of the battery, and consequently decreasing the cost per kWh of the final battery. In addition, the reuse of the components will contribute to the cost reduction of the battery. To this end a complete Life Cycle Analysis of the new battery components will be performed. To take up these challenges, academic and private organisations have partnered up in the AMELIE consortium. As the developments in this field are extremely interconnected, improved Lithium ion batteries for automotive sector can be manufactured only by the synergistic optimisation of all their components: active materials and binders for electrodes, gel polymers, lithium salts and solvents for the ionic conductors. Although innovative materials are a key lever of such improvements, the cell design will be essential for both improved performances and safety.
