Abstract
The presently disclosed concepts relate to ultra-efficient EV battery recycling systems. Alkali metal extraction (and in particular lithium extraction) is accomplished using a solid electrolyte membrane. By using a solid electrolyte embedded in a matrix, alkali metals, in particular lithium can be (energy-wise) efficiently separated from feed solutions. The energy used to initially extract lithium from a feed solution is stored as electrochemical energy, which electrochemical energy is reclaimed in subsequent extraction processing steps. This energy storage and energy reclamation is performed in continuous ultra-efficient ongoing cycles. Since irrecoverable energy losses incurred in each cycle are limited to negligible amounts of joule heating of the system components and feed solution, the system can be sustainably powered using locally-generated renewable energy.
