AB Demand of lithium is expected to increase drastically in coming years driven by the market penetration of electricvehicles powered by Li-ion batteries, which will require faster and more efficient Li extraction technologies thanconventional ones (evaporation in brines). The Electrochemical Ion Pumping Cell (EIPC) technology based on theuse of Faradaic materials is one of the most promising approaches. However, its relatively short lifespan preventsits commercial deployment. Herein, a new EIPC concept based on the use of semi-solid electrodes is proposed forthe first time, which takes advantage of the rheological characteristics of semi-solid electrodes that enable simpleand cheap regeneration of the Regenerative Electrochemical Ion Pumping Cell (REIPC) systems after reaching itsend-of-life. A proof-of-concept for REIPC is accomplished by simple replacement of the semi-solid electrodedemonstrating a remarkable electrochemical performance (e.g. 99.87%cycle− 1, 99.98%h− 1, 3–4 mAh cm− 2)along with a competitive ion separation (e.g. 16.2 mgLi⋅gNiHCF− 1, 4 gLi m− 2 and 15.6 Wh⋅mol− 1). The use of semisolid electrode offers other unique features such as a significant cost reduction of 95% for every regenerationregarding conventional EIPC, proving that REIPC concept successfully addresses the issues associated to thesustainability and recyclability of the conventional EIPC's for lithium capturing.
