Negative electrolyte management system

An electrolyte management system for a redox flow battery cell, comprising:

• a battery cell with a positive electrode compartment and a negative electrode compartment;
• a redox rebalancing cell arranged between the redox flow battery cell and an electrolyte storage tank, the redox rebalancing cell including an electrode electrically shorted to a negative electrode of the battery cell;
• and
• a negative electrolyte circulated through the negative electrode compartment, the redox rebalancing cell, and the electrolyte storage tank.
