Abstract: A flow battery system can include at least one pair of electrolyte storage, a first battery stack, and a second battery stack. The electrolyte storage pair can include an anolyte storage configured to contain an anolyte solution, and a catholyte storage configured to contain a catholyte solution. The first battery stack can be fluid communication with the electrolyte storage pair. The first battery stack can also be configured to receive electrical energy from a power source and to facilitate redox reactions storing the received electrical power as chemical energy by the anolyte and catholyte solutions. The second battery stack can be in fluid communication with the at least one pair of electrolyte storage. The second battery stack can also be configured to supply electrical energy to an electrical load, and to facilitate redox reactions releasing chemical energy stored by the anolyte and catholyte solutions as electrical energy to the load.

Abstract: A method for reducing moisture in a battery enclosure is presented. The method may reduce battery degradation during some conditions. In one example, moisture is controlled in a battery enclosure by a desiccant material. In another example, moisture is controlled in a battery enclosure by periodically passing electrical current through a Peltier device.
