Highlights

The RADICAL project presents its latest advances on the stability of nitroxides and the strategies implemented to further understand degradation mechanisms.

LEGEND designs electrolytes for divalent cation batteries using molecular simulation and AI.

Research on high-power batteries and strategic Franco-German collaboration.

The liquid electrolyte BMimF/CH₃CN enables the generation of free fluoride ions (F⁻), ensuring high conductivity, low overpotential, and improved performance with Pb/PbF₂ and BiF₃.

A single synthesis method is not sufficient to provide a relevant range of materials to enhance the power performance of electrodes for the devices envisioned in the HIPOHYBAT project. Thanks to the synergy of the approaches considered—surface modifications, defect introduction, and composite development—the targeted performance for high-power sodium-ion batteries and hybrid batteries is within reach. These strategies were presented at the PEPR Batteries Day in Grenoble in January 2026.

Multi-scale operando tools to understand the mechanisms of Gen4/Gen5 batteries.
