idea is to use powder contained in tubs. the walls will have a perforated mesh whos holes angle up and out so that the powder cannot escape. Nickel wires will be placed in the powder to conduct out of the cell. -Contact area is not optimal - that's why they use liquid electrolyte?-MJ

design

ideas

• add a couple super capacitors to get some cold cranking amps?
  • not sure if that would work but just an idea

• two tubs with grid on four sides of each or shared center.

• fins for surface area.

• cages that snap in to the bottom of a tub shared by two cages.

• might use a part of a sphere for the snap in idea.

• tub lid
  • tub lid will need some sort of two pole terminal block
    • from cages below
    • to next tub or out for use
  • might need some sort of cover for uninsulated wires from cage
  • vent for gas?

• need to make parametric for 10 tub battery
  • maybe input number of rows and columns so it can be a single row or two side by side

chemistry

http://en.wikipedia.org/wiki/Nickel%28II%29_hydroxide

calculations

• nickel hydroxide Ni(OH)2
  • 4.10 g/cm3

to research later

would liked to have an info for:

Ah/gram

impact surface area has

calculate AWG output based on dimensions of cage and cells

bom

hardware

nickel, aluminum, brass?
