It is technically repairable, but I suspect the other driver's insurance company will call it a total loss and do everything they can to minimize payment. A hit like that should not damage the battery. If they do repair it, make sure the body shop does not bake the car in a paint drying oven unless the battery is removed first.
My 2011 had a lot more damage in the rear, but no damage in front. It was repairable, but the other driver's insurance company declared it a total loss. I strongly recommend that you take lots of photos of the interior and undamaged portions of the car to document its condition. My car suffered additional damage in the insurance company's storage yard (grease stains throughout the interior and damage to the front from being moved around with a large fork lift). Since I did not have photos of the condition when it left my possession, it was difficult to fight their low-ball appraisals. I had to fight hard and drag out the negotiations for a month or two to get a somewhat reasonable settlement.
Edited to add: Nissan quit providing the front towing eye some time during the 2015 model year. Early ones came with it while later ones did not.
