Abstract
Durability of an energy conversion and storage system is increased by rebalancing the electrolyte composition used in the system. The storage system includes a main device, a sub device, an electrolyte, and a device for directing the electrolyte from the main device to the sub device. The system has re-balancing capacity for the electrolyte properties of the electrolyte in the sub device. The as re-balancing capacity includes rebalancing pH of the electrolyte and/or rebalancing conductivity of the electrolyte and/or rebalancing solubility of the electrolyte.
