The lithium-ion battery (LIB) is the most widely used technology for portable electronics and electric vehicles. However, the growing demand for high-performance batteries requires the development of new materials and architectures. Solid-state batteries (ASSB) are seen as a promising alternative to conventional lithium-ion batteries, thanks to theoretical improvements in safety, energy density and life cycle. In addition, the use of active organic materials in ASSBs could provide a sustainable, cost-effective solution to the current problems associated with the rare metals that make up our batteries. However, simple electroactive organic molecules are often less stable than inorganic materials, requiring further research to optimize their use in batteries. This thesis aims to explore and optimize the use of small organic molecules in all-solid-state batteries in order to achieve a high energy density. More specifically, the research concentrates on the compatibility of selected organic cathodic materials, such as simple quinones and glyoximes derivatives with high specific capacitiy, with some solid electrolytes. The study also explores the impact of various parameters on the performance of these batteries. Finally, future research directions are proposed to further advance the development of organic all-solid-state batteries and contribute to the global shift towards more sustainable and efficient energy storage solutions.Solid-State BatteryOrganic active materialLithium anodetext::thesis::master thesisthesis:46789
