Rechargeable batteries self-discharge and get damaged if left unplugged for too long, and explode if left plugged in. They are not ideal for something you want to pack away in an emergency kit.

Almost everything in an emergency kit expires. But many name brand alkaline and non rechargeable lithiums are now rated for ten years shelf life. In addition there are rechargeable eneloop branded batteries rated for slower discharge rate.
