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
principles
- maximize 3d printing
- utilize parametric customization
- avoid complicated chemical processing
- no nickel plating
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?
- tub lid will need some sort of two pole terminal block
- 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
- might move side spacers onto cages. 3 sphere divots. 1 middle top and 2 side by side bottom, flip on opposite face. 1 or 2 on non mesh sides.
sketches
single cell separated by a grid.

scad work
parametric code to produce stl files for custom sized 3d prints.

chemistry
KOH corrosion
- need to find out if ABS or PLA or other plastics will hold up to corrosion by the electrolyte
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
analysis
Need to find a battery analyzer.
bom
hardware
nickel, aluminum, brass?
- all thread
- bolts
- washers
- nuts
