If you make the battery pack bigger and hide the top end of the capacity, the taper appears to be less and the charging rate when "full" is higher. I can't remember which one, but one of the upcoming German BEV SUVs appears to use this technique.
the Model S60 uses this as its essentially an S75 which in itself is more an 80.
But it charges from like 10 - 60% without tapering and only tapers very slightly until 90%.
