Disclosed are approaches for recycling LIBs where lithium is recovered before the other node metals in order to increase the amount of lithium recovered. For such approaches, the other node metals need not be further refined or recovered and, despite the small loss of these other node metals as impurities in the first-recovered lithium, the available alternative dispositions for these other node metals—such as in the form of multi-metal-oxides (MMO)—can render the recovery of lithium before the other node metals to be advantageous. Several such approaches may feature nitration, roasting, lithium trapping, and/or other innovative features to facilitate greater and purer recoveries of the target LIB components.
