  • REDOX FLOW BATTERY AND METHOD FOR OPERATING THE BATTERY CONTINUOUSLY IN A LONG PERIOD OF TIME
    Publication number: 20110300417
    Abstract: The present invention provides a redox flow battery comprising a positive electrolyte storage tank and a negative electrolyte storage tank, wherein the positive electrolyte storage tank and the negative electrolyte storage tank is kept to be in liquid communication through a pipe, wherein the length-to-diameter ratio of the pipe for the liquid communication is not less than about 10. The present invention also provides a method for operating the redox flow battery continuously in a long period of time.

  • Vanadium redox battery incorporating multiple electrolyte reservoirs
    Patent number: 7740977
    Abstract: A vanadium redox battery energy storage system (“VRB-ESS”) capable of modularly incorporating additional electrolyte reservoirs to increase energy capacity while allowing for efficient low-volume operation is disclosed. The VRB-ESS of the present invention may efficiently operate using a first volume of electrolyte solution, while maintaining a second volume of electrolyte solution to be made available to the VRB-ESS as additional energy storage capacity is required. Additionally, a cap mechanism to allow the VRB-ESS of the present invention to employ an industry standard IBC container as a secondary electrolyte reservoir is disclosed.
