I have been giving some thought to the battery cooling problem.
Air cooling is just not going to work because of the the required very close packing between cells.
But suppose you could sandwich a serpentine metal pipe between two aluminium plates, and circulate cooling water?
Pack those between cells, or alternate cells.
Even a simple single "U" shape pipe may be sufficient, because the aluminium will conduct very well over it's whole surface area back into the battery.
Perhaps some quarter inch copper pipe epoxied between two flat aluminium plates.
Coat the pipe with epoxy, and squash down on the whole thing in a hydraulic press until the epoxy cures.
There is not a lot of heat to remove, just something to stop the temperature from very slowly building up over time.
Cheers, Tony.
