I saw his Bankai shatter completely, so I doubt it was sealed.

It was stated by Granz that Renji would not be able to use his bankai in that room.

And what do you know on the next page he even states he sealed Renjis bankai.

"If that were the case, Ikkaku or Mayuri would have different Shikais "

Ikkakus and Mayuri bankais were remodeled not their shikais. Plus they were remodeled with the same Asauchi. Renji and Ichigo got a whole new Asauchi.

"On a side note, do Bankai weapons have to be completely destroyed in order for them to never recover? Does that imply that they would recover if only a part breaks?"

If a bankai is broken/damaged in anyway they can not be repaired only remodeled to function at a level close to what the original was. Ichigo's bankai was cut/broken in half and was stated to not be able to be restored.
