Electrochemical Energy Storage and Conversion (ST2E)<\/span><\/h2><\/div>

The ST2E<\/strong> (Stockage et Transformation Electrochimiques de l’Energie – Electrochemical Energy Storage and Conversion)<\/strong> research team focuses on the synthesis<\/strong>, multi-scale characterization<\/strong> and analysis of the physico-chemical mechanisms<\/strong> at the heart of electrochemical energy storage and conversion devices. Structured around three main areas – batteries<\/strong>, supercapacitors & power batteries<\/strong> andhydrogen-fuel cells-electrolysers<\/strong> – the team brings together some fifty researchers, lecturers, engineers, post-docs and PhD students. It draws on a wide range of skills in inorganic and organic chemistry<\/strong>, oxide physical chemistry<\/strong>, electrochemistry<\/strong>, modeling<\/strong> and materials science<\/strong>. <\/p>\n

With its recognized expertise, ST2E designs functional materials<\/strong> (electrodes with ionic and\/or electronic conduction, solid electrolytes) and integrates them into operational devices, in conjunction with academic and industrial partners. Research aims to improve the performance<\/strong>, lifespan<\/strong>, safety<\/strong> andscope of use<\/strong> of systems, in particular by optimizing materials, controlling interfaces and designing new architectures. Eco-design and materials recycling<\/strong> are also integrated into the team’s overall approach.<\/p>\n<\/div>
