(1) When you recharge an alkaline battery and it explodes, why does it
explode? Is it because of a build up of hydrogen gas from action of
KOH on the Zn powder?

default expressed the useful opinion that the gas is water vapor heated
by the current. In that case, if one were to use some method for cooling
the battery while it is recharged, or perhaps if one used a circuit that
recharged it extremely slowly, perhaps one could charge it to significantly
higher voltages. How high a voltage could one hope to get?
