China Sourcing

  • $32 for 100Wh - 80Ah bat cells- [8]
  • This means 4kW would be $1280, causing an energy transition to off grid.
  • 800Ah - weighs 57 kg. [9]
  • 1200Ah for $200 each? [10]. That would be $140/kw, unreal. Table says 62kg filled. If weight in nickel is 1/5, that is only 12kg nickel. So the price would be $120 in materials. They are selling at $140.

Notes

  • Nickel-Iron Battery/Sourcing - more info on nickel hydrate
  • Nickel is 20% of the battery - [11]
  • If nickel is 1/5 the battery, and nickel is $6/lb raw - then price of battery is $1/lb based on nickel cost. Thus a 50 kg battery should be $100 in materials only. If nickel hydrate was obtained readily from nickel.
