CHARGING / DISCHARGING

A device that stores electrical energy using the sodium ions (Na+) and
water in seawater, with seawater serving as the electrolyte

CHARGING

  • Utilizes the sodium present in seawater during charging
  • OH- (hydroxide ions) in the seawater generate O2 and H2O,
    separating electrons (e-) in the process (OER)
  • The sodium ions produced move to the anode through the electrolyte
  • Electrons (e-) travel through the installed wiring

DISCHARGING

  • Oxidation occurs at the sodium in the anode,
    producing ions (Na+) and electrons (e-)
  • The sodium ions (Na+) move to the cathode (seawater) through the electrolyte
  • The electrons (e-) travel through the circuit to the cathode, forming an electric current
  • At the cathode, sodium ions (Na+),
    electrons (e-), dissolved oxygen (O2) in the seawater, and
    H2O combine to produce sodium hydroxide (NaOH) (ORR)

KEY ADVANTAGES

  • Eco-friendly

    Seawater-based, minimizing environmental pollution

  • Low Cost

    Replaces rare metals, reducing production costs

  • High Safety

    Low risk of fire and explosion
