Brom, with the chemical symbol Br, is a halogen discovered in 1826 by the French chemist Antoine-Jérôme Balard. Belonging to the halogen group, it is a non-metallic element. Bromine is found on Earth in various minerals, such as carnallite, and is also present in seawater, constituting approximately 65 ppm.

The applications of bromine are diverse. It is used in the chemical industry for the production of flame retardants, disinfectants, and solvents. In medicine, bromine is employed in some pharmaceuticals, and it also plays a role in photography.

Future applications could focus on innovative technologies in energy storage. Bromine-based batteries, particularly flow batteries, are being researched to enable cost-effective and efficient storage of renewable energies. These technologies could help address the challenges of the energy transition and optimize the utilization of renewable resources.
