Good explanation, what I read/heard was that "pouch cells" should be clamped together so an evenly applied force between anode/cathode that guarantees an evenly spread current draw or charge from the plates. This way it will limit the "hot spots" in the battery cell, this is the place where gassing is created. Limiting the charge/discharge rate will reduce the stress and help with avoiding swelling.
I would discourage using (heavely) swollen cells, it will get worse overtime because the plates won't make good "contact" anymore. Maybe you could take the risk with small lifepo cells, but with li(-ion)po it gets dangerous verry quickly.
