The woman, who was arrested last Wednesday, faces two counts of attempted murder, possession of explosives with intent to endanger life and preparation of terrorist acts.
Detectives were given more time by a court to question her as part of the investigation.
Two young male officers escaped injury when two pipe bombs were thrown at them in the early hours of Tuesday 28 May on the Crumlin Road.
The pair were targeted as they responded to a 999 call in the area.
They had just got out of their vehicle when the two missiles were hurled at them.
The pipe bombs, which were described as large homemade grenade-type devices, exploded just yards away from their armoured vehicle.
The woman will appear before Laganside Court on Wednesday.
Meanwhile a 25-year-old man arrested in England on Saturday remains in custody after being brought to Northern Ireland for questioning.
