They don't consume their materials. It's an energy storage medium, not a fuel. From what I've read the recycling yield is quite high, though not quite 100% due to that nasty second law of thermodynamics. I imagine big utility-scale and car-size batteries are easier to recycle than the tiny cells found in laptops and phones. The latter tend to be less standard and due to their small size and exotic packaging are going to have more packing material and plastic vs. "good stuff" like lithium.
