Development of novel SOlid MAterials for high power Li polymer BATeries (SOMABAT). Recyclability of components.


The research leading to these results has received funding from the European Community's Seventh Framework Programme (FP7/2007-2013) under grant agreement n° 266090 (SOMABAT)




SOMABAT aims to develop more environmentally friendly, safer and better performing high power Li polymer battery by the development of novel breakthrough recyclable solid materials to be used as anode, cathode and solid polymer electrolyte, new alternatives to recycle the different components of the battery and cycle life analysis.

This challenge will be achieved by using new low-cost synthesis and processing methods in which it is possible to tailor the different properties of the materials. Development of different novel synthetic and recyclable materials based carbon based on hybrid materials, novel LiFePO4 and LiFeMnPO4 based nanocomposite cathode with conductive polymers or carbons, and highly conductive electrolyte membranes with porous architecture based on fluorinated matrices with nanosized particles and others based on a series of polyphosphate/polyphosphonate polymers will respond to the very ambitious challenges of increased energy density, battery lifetime and safety.


An assessment and test of the potential recyclability and revalorisation (re-use) of the battery components developed and life cycle assessment of the cell will allow the development of a more environmentally friendly Li polymer battery in which approx 50 % weight of the battery will be recyclable and a reduction of the final cost of the battery down to 150 €/KWh are targeted.


The consortium is made up of experts in the field who are complementary in terms of R&D expertise and geographical distribution.
