Abstract
Systems and methods of the various embodiments may provide a refuelable battery for the power grid to provide a sustainable, cost-effective, and/or operationally efficient solution to energy source variability and/or energy demand variability. In particular, the systems and methods of the various embodiments may provide a refuelable primary battery solution that addresses bulk seasonal energy storage needs, variable demand needs, and other challenges.
Claims10
A method of operating a refuelable battery, comprising:
- circulating an electrolyte in a battery chamber, the electrolyte moving between a seeded trap area and an area including a cathode and an iron-containing anode;
- discharging the refuelable battery to generate oxidized anode material from the iron-containing anode, the oxidized anode material including iron oxide, iron hydroxide, or a combination thereof;
- providing air into the battery chamber during discharge of the refuelable battery;
- draining the electrolyte from the seeded trap area;
- with the electrolyte drained from the seeded trap area, removing the oxidized anode material from the seeded trap area;
- and
- inserting another instance of the iron-containing anode into the refuelable battery.
