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.
- Electrochemistry;
- Storage of renewable energy;
- Hydrogen production.
As part of the European NextBat project, CEA-Liten has designed a battery module in which a single fluid simultaneously cools and compresses the cells. This architecture aims to extend cell lifespan and improve system safety, particularly in intensive applications.
When thermal runaway occurs in a battery, the gases emitted (or generated) can ignite! CEA-Liten has developed a system to manage these gases to prevent this type of event, which often involves the projection of fragments and the release of toxic fumes. The initial results have been promising.
