The best way I’ve heard it is imagine the battery like is like football stadium. Now when everyone tried to leave at once there is a lot of congestion sand it takes a long time for those first people (ions?) leaving to get out. When it’s at lower capacity all of the remaining people (ions?) Can get out easier and faster.
