All-iron batteries

  • The total cost of materials is $0.1 per watt-hour of capacity at wholesale prices.
  • This battery may be a useful component of open source hardware projects that require a safe and ecologically friendly battery.
  • This is also one of the few battery chemistries that can be built safely in a DIY setting.
  • Iron batteries have lower specific energy (watt-hours per kilogram) than commercial rechargeable batteries, NiMH type or Lithium-ion type, but have low-cost reagents and present opportunities for simpler construction and experimentation.
