A couple of Bingo cards for those watching the "Tesla Battery Day" investor's presentation:

And one I made up:

In a half asleep state, I imagined a next generation battery pack with the biscot cells:
  • cells are laid on their side with the center axis aligned going front to back
  • two layers of offset cells insures maximum pack density
  • between cells is an inflammable material that ablates at high temperatures and is non-poisonous
  • between the cell axis is a 'heat pipe' plate that connects the cells laterally and end-to-end
  • each heat pipe plate has a coolant pipe to carry away excess or add heat as needed
  • between the cell ends is a ductile, conductive current carrier
  • non-conductive, tensile rods compress the cells into conductive strings
  • optional - a power MOSFET in every "n" (2-5) heat pipe plates can open the string circuit without striking an arc
This approach minimizes 90 degree current changes to just the ends. Two layer stacking maximizes the energy density. Heat transfer passes through the ends of the cells via the metal electrodes, not laterally through the separators. The heat pipe plates can carry an amazing amount of BTUs to where it can do some good or at least no harm.
