do blood cells die? if yes, why doesn't the blood in blood banks die?

The blood in blood banks are diluted with a chemical called Urotenian which allows for a constant flow of oxygen and sources that allow it to live outside the human body.

Good question and I am not 100% sure I know the answer. However, to call human red blood cells alive is a stretch. red blood cells are basically little packs of hemoglobin. Now I also think they require some metabolism to maintain pH balance (e.g. the function of chloride pumps) so when that stops things probably go pretty bad, but if no gas exchange is happenening you should not need this .
Like I said ... Good question

It is kept refrigerated, which keeps the cells alive for a specified period of time, just like fruits in your home refrigerator. The blood has to be used within that allotted time. After that the cells do begin to die.

some protective arrangement are done to prevent the frequent death of blood cells.
