Advanced manufacturing processes for Low Cost Greener Li-Ion batteries

Basic data for this project

Description

GREENLION is a Large Scale Collaborative Project with the FP7 (topic GC.NMP.2011-1) leading to the manufacturing of greener and cheaper Li-Ion batteries for electric vehicle applications via the use of water soluble, fluorine-free, high thermally stable binders, which would eliminate the use of VOCs and reduce the cell assembly cost. GREENLION has 6 key objectives: (i) development of new active and inactive battery materials viable for water processes (green chemistry); (ii) development of innovative processes (coating from aqueous slurries) capable of reducing electrode production cost and avoid environmental pollution; (iii) development of new assembly procedures (including laser cutting and high temperature pre-treatment) capable of substantially reduce the time and the cost of cell fabrication; (iv) lighter battery modules with air cooling and easier disassembly through eco-designed bonding techniques (v) waste reduction, which, by making use of the water solubility of the binder, allows the extensive recovery of the active and inactive battery materials; and (v) construction of fully integrated battery module for electric vehicle applications with optimized cells, modules, and other ancillaries. Accordingly, GREENLION aims to overcome the limitations of present Li-ion manufacturing technology for electric vehicle batteries with the goal to: 1- perform breakthrough work to position Europe as a leader in the manufacturing of high energy and environmentally benign batteries; 2- develop highly effective eco-designed processes; 3- develop automotive battery module systems with: A) specific energy higher than 100 Wh/kg and specific power higher than 500 W/kg with respect to the overall weight of the system; B) coulombic efficiency on average higher than 99.95% during cycling; C) cycle life of 1,000 cycles with 20% maximum loss of capacity upon cycling between 100% and 0% SOC; and D) evaluate their integration in electric cars and renewable energy systems.
