When these batteries are overheated, can they be repaired?? Or are the cells completely knackered?

Depends what you call overheat. They can get remarkably hot during heavy use and recharging without serious damage. Most batteries have a fuse internally but not a thermal cutout - that is usually part of the charging mechanism and limits/stops the charging process if they are too hot. I very much doubt that you could damage a battery by heat alone - the fuse would likely blow before the batteries achieved such a heat that you ruined them. If your battery is dud (measures 0V) then the fuse pretty much WILL have blown. They can be fixed easily but this depends on your ability to dismantle the battery and get at the fuse in the first place.

Physically the batteries cells each have 'vents' to prevent explosion when overheated or short-circuited. You can, however, severely restrict their useful lifespan by overheating them.
