I would be interested in your source for that. Batteries are already made of very many different materials, it’s not as though glue is some sort of special material. (The label of, say, AAA batteries is glued to the metal container. The label of the Li-Ion battery of my Nokia phone is also glued to the plastic container. Maybe Apple uses a bit more glue – but glue shouldn’t be something completely new in battery recycling.)
