A novel spray-based deposition method has been developed to fabricate a new generation of supercapacitors. Mixtures of graphene and carbon nanotubes have been used for their fabrication, in order to improve their energy storage (by increasing the surface area) and their power (creating an optimal distribution of pores). This technique was first developed in 2006 at Thales Research and Technology on a small facility previously used for the fabrication of gas sensors based on Carbon Nanotube mats. Thanks to the Graphene Flagship project Thales and M-SOLV have jointly developed a pre-industrial level machine to achieve large surface samples 30cmx30cm. M-SOLV is presently developing in collaboration with NAWA technology (supercapacitor producer), a new generation of roll-to-roll machine to finally implement this technique in a pilot production line and increase the TRL of this technology. In this presentation we will show the current progress and the design of the new machine funded by the Graphene Flagship.
Dr. Paolo Bondavalli is in charge of the transverse topic on nanomaterials at Thale Research and Technology. Presently his work is focused on the development of new materials (e.g. graphene, cnts, nanowires) for the new generation of electronics devices and for energy storage applications, memristor, electromagnetic shielding. Dr Bondavalli has received his Hdr in 2011, at Paris-Sud on a work on "devices based on random network of carbon nanotubes". During the last five years, he has participated, also as coordinator, in several EU projects (concerning CNTs, graphene, spintronics, energy) and ANR projects. He is involved in the Graphene Flagship initiative. He recently issued a book on Graphene ("Graphene and Related Materials: Properties and Applications" Ed Elsevier, pp 192, 2017).
Thales Group Competence Centre Microelectronics is Thales's industrial and technological competence centre for (micro)electronics packaging, interconnections and assemblies. Located in France, the site of Etrelles (Brittany) designs, engineers and manufactures high-added value electronics modules and systems dedicated to harsh environments or specific systems. With 600 skilled staff, 10000sq. m of industrial facilities of which 5700sq. m clean rooms, the GCC Microelectronics team performs pioneering work in electronic technologies to boost the performance and reliability of applications facing critical functional or packaging constraints. We provide innovative and robustified electronic solutions integrative of new generation materials and advanced interconnection and assembly processes.
