Discovering Advanced high potential Materials for high Energy density Li ion batteries – DAME

DAME is a 42 month collaborative public-industry project, which answers to the challenge “clean, sure and efficient energy” and more particularly concerning the electrochemical storage device. The main DAME objective is to demonstrate a 500 Wh/kg Li-ion electrochemistry based on new nanostructured cathode materials recently discovered
and patented by SAFT combined with silicon based anode materials. But many issues need to be solved on this material (like high polarization leading to low energy efficiency and poor cycle life) and requires synthesis and composition optimization. Fine crystallographic and nanostructure characterization of the new cathode material are necessary to understand the mechanism for charge-discharge mechanism, high polarization and ageing mechanism. The success of DAME will make emerging new high energy density and low cost batteries which may be used for strategic applications like energy storage system for renewable energy and electric vehicle. In that respect, it must be emphasized that DAME officially recognized by the competitiveness hub MOVEO. DAME project is organized in 3 technical work packages supervised by the coordination work package. Optimization of synthesis conditions and composition with basic characterization will be implemented in WP1, (leader CRISMAT). Fine and cutting edge characterization as well as mechanism understanding will be studied in WP2 using an arsenal of complex techniques like neutron diffraction, SAXS, WAXS, XANES, HRTEM techniques (leader NEEL Institute). And finally fine electrochemical characterization, electrode formulation and prototype cell assembly and testing will be carried out in WP3 (leader SAFT).
