Dr. Hab.
In 2000, Angel Kirchev began his career as a researcher at the Bulgarian Academy of Sciences (BAS) when he joined the BAS Institute for Electrochemistry and Energy Systems' (IEES) Lead Battery Department. During his tenure at BAS-IEES, he was involved in several European-Commission-funded R&D projects, the Advanced Lead-Acid Battery Consortium, and the US Army's European Research Office.
During that time, he also pursued his PhD, with a dissertation on oxygen recombination processes in sealed lead-acid batteries—research that won him a Dave Rice Award in 2005. The same year, he joined CEA-Liten's energy storage team.

How can you design batteries with the lowest possible impact on the environment? Well, together with Laboratoire G-SCOP, CEA researchers combined LCA with parametric models. This unprecedented method allows them to quantify the impact of design choices on a battery’s environmental impact, including its lifetime.
By combining X-ray diffraction and small angle scattering at the ESRF, electrochemical analysis and gas detection, CEA researchers have managed to track the degradation of an overcharged Li-ion battery in real time. This breakthrough brings great opportunities, including the ability to identify the optimal operating range, refine aging models, and improve post-production quality models.
