Final Report Summary - ILLIBATT (Ionic liquid lithium based batteries)
The specific objectives of ILLIBATT were the following:
(i) development of a green and safe solid-state electrolyte chemistry based on ionic liquids and unique ionic liquid based composites with high performance;
(ii) use of novel nano-structured high capacity anodes, prepared with the help of novel ionic liquids;
(iii) investigation of the peculiar electrolyte properties and the specific interactions of these electrolytes with advanced commercial and self-prepared electrode (anode and cathode) materials with the aim of understanding and improving the electrode and electrolyte properties and thus their interactions;
(iv) construction of rechargeable lithium cells with optimised electrode and electrolyte component.
Accordingly, ILLIBATT aimed 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 nano-structured electrode materials which combination allows to realise true solid state lithium batteries;
3. develop all-solid-state concept-cells operating at room temperature with energy higher than 180 W/kg with respect to the overall weight of the cell, coulombic efficiency in average higher than 99 % during cycling, cycle life of 1000 cycles with 20 % maximum loss of capacity, cycling between 100 % and 0 % System on a chip (SOC) and evaluate their integration in renewable energy sources.
