Saft’s products and solutions are essentially nickel-based batteries, primary lithium and new-generation lithium-based batteries and battery systems. They serve in a wide range of back-up or mission-critical applications in civil and military markets around the world.

Key personnel

Dr. Christian Jordy:

Senior Scientist in charge of developing new high capacity materials for positive and negative electrodes. Professional experience: Engineer degree in chemical engineering & PhD in metallurgy on Ni-MH battery (1993) (one patent & 2 papers). Working at Saft since 1993: on NiMH batteries in research and development teams for 8 years on conventional Li-lon batteries (research) for 4 years and on prospective Li-lon systems since 2007. In Li-lon batteries, the research topics were related on positive materials, new Si and Sn based anode materials and on new positive materials. Responsible for the battery development of new NiMH cells in several US progams to design new long life batteries for EV and aircraft applications. In charge of several tasks in European and national projects and presently coordinating internal collaborations with national and international universities and industrial companies. Confirmed experience on new /+/ and /-/ electrode material design, electrode formulation, cell design, safety, ageing mechanisms of Ni-MH and Li-lon batteries.

Experimental facilities

The role of SAFT will be mainly focused on the synthesis of electrolyte-C-active material synthesis, and on the testing of electrochemical energy storage systems. The experimental equipment available for the project comprises the following instrumentations: SEM/ -EDAX microscopes, BET, PSD, X-Rays diffraction, glove box for the assembly devices in clean atmosphere, DSC, ATG, gas chromatography, FTIR, viscometer, ICP, X-Ray fluorescence, collaboration on plasma device; Impedance spectroscopy; galvanostat, potentiostat; equipment for electrode manufacturing, equipment for cell assembly; ball milling; furnaces; spray dryer; powder homogenizer.
