ILLIBATT - Ionic Liquid based Lithium Batteries

Grunddaten zu diesem Projekt

Beschreibung

ILLIBATT aims to develop safer and better performing Li batteries that make use of solid-state electrolytes, containing non-volatile and thermally stable ionic liquids, new nanostructured anodes and advanced cathodes. These newly developed materials are expected to be useful in a wide range of different cell sizes: from small, e.g. micro-batteries, to large, e.g. delocalised storage units (10-20kWh). ILLIBATT has 4 key objectives: (i) development of a green and safe solid-state electrolyte chemistry bas ed on ionic liquids and unique ionic liquid based composites; (ii) use of novel nano-structured high capacity anodes, prepared with the help of novel ionic liquids; (iii) investigation of electrolyte properties and the specific interactions of these electrolytes with advanced commercial and self-prepared electrode materials with the goal to understand and improve the electrode and electrolyte properties and thus their interactions; and (iv) construction of rechargeable lithium cells with optimised elect rode and electrolyte components. Accordingly, ILLIBATT aims to overcome the well-known technical problems of the present rechargeable lithium battery technology with the goal to: 1- perform breakthrough work to position Europe as a leader in the developing field of high energy and environmentally benign and safe batteries and to maintain the leadership in the field of Ionic Liquids; 2- develop appropriate solid electrolytes and nanostructured electrode materials which combination allows to realize true solid state lithium batteries; 3- develop all-solid-state prototype batteries operating at room temperature with (4-6): 4- specific energy higher than 180Wh/kg with respect to the overall weight of the prototype; 5- coulombic efficiency in average higher than 99% during cycling; 6- cycle life of 1,000 cycles with 40% maximum loss of capacity, cycling between 100% and 0% SOC; 7- evaluate their integration in renewable energy systems
