Abstract

CEA Tech Nouvelle-Aquitaine, created in 2013, is currently setting up a new laboratory focused on both the development of materials and the high throughput screening to accelerate the discovery of materials for the next generations of Li-ion batteries. For that, the CEA Tech Nouvelle-Aquitaine acquires different vacuum deposition equipment integrated in glovebox including two Atomic Layer Deposition tools (ALD). One, which is a plasma enhanced ALD, will be dedicated to coatings on planar substrate like foils and electrodes whereas the other one will be used for the depositions on powders.

Interfaces in between electrodes and electrolyte constitute one the main challenges to overcome for the next generations of Li-ion batteries. In this context, ALD is promising method to develop high quality interfaces. Indeed, ALD is a self-limiting growth process allowing the deposition of material layer-by-layer. Thus, high quality and conformal nanometric coatings are achieved at relatively low temperature (<350°C) whether on powder or porous 3D frameworks.

We are seeking for an outstanding applicant who will qualify the ALD tools and develop new coatings for the next generation of Li-ion batteries. She/he will have at her/his disposal new infrastructures including state-of-the-art ALD and characterizations equipment. In-situ ellipsometer and Residual Gas Analyzer connected to the ALDs will be used to properly calibrate the growth and deeply understand the involved reactional mechanisms.
