Don't forget that conventional current flows in the direction of the diode "arrow", from + to - . This is the opposite direction from the actual flow of electrons - they flow from - to + . This works out mathematically because electrons carry a negative charge, so when they are flowing to the right, the conventional current, which is positive, is flowing to the left.
I think it was Ben Franklin who made the mistake originally, or maybe someone else. At any rate, when you discharge a battery, the electrons are flowing from the - to the + . When you charge it, they are going the other way.
That's what happens when you define the direction of current before you know what it is made of. Had a 50-50 shot to get it right and blew it.
