Abstract: Aspects of the invention are related to a system for replacing electrolyte in a battery. The system comprising: a first tank for holding off-board electrolyte and a second tank for receiving on-board electrolyte. The system further includes fluid conduits to connect the first tank and the second tank to the battery and a controller to control transfer of the on-board electrolyte from the battery to the second tank and to control transfer of off-board electrolyte from the first tank to the battery.

Abstract: The present invention relates to safety methods and mechanisms for treating electrolyte solutions in batteries, specifically metal-air batteries. Systems and methods of the invention protect the battery, protect the battery operator and protect the environment from potential material hazards. This invention provides materials for arresting a potentially hazardous electrolyte solution by forming solid or gel porous polymer structures. The polymer porous structures consume or confine the electrolyte solution thus preventing its hazardous potential.
