Angel KIRCHEV

Dr. Hab.​

Senior Expert​

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.
