Hydrogen-Bromine Flow Battery

Lawrence Berkeley National Laboratory (LBNL) is designing a flow battery for grid storage that relies on a hydrogen-bromine chemistry which could be more efficient, last longer, and cost less than today's lead-acid batteries. Flow batteries are fundamentally different from traditional lead-acid batteries because the chemical reactants that provide their energy are stored in external tanks instead of inside the battery. A flow battery can provide more energy because all that is required to increase its storage capacity is to increase the size of the external tanks. The hydrogen-bromine…
