Easily recyclable lithium‐ion batteries: Recycling‐oriented cathode design using highly soluble LiFeMnPO₄ with a water‐soluble binder

Recycling lithium-ion batteries (LIBs) is fundamental for resource recovery, reducing energy consumption, decreasing emissions, and minimizing environmental risks. The inherited properties of materials design are not commonly attributed to the complexity recycling LIBs their effects on process. state-of-the-art battery methodology consequently suffers from poor efficiency high consumption issues with cathode binder material. As a feasibility study, high-energy-density material LiFeMnPO4 water-soluble polyacrylic acid (PAA) extracted dilute hydrochloric at room temperature under oxidant-free conditions. wholly leached purity suitable reuse. easily separated its constituent reduces during by 20% 7%, respectively. This strategy utilized fabricate recyclable-oriented LiFeMnPO4/graphite PAA carbon paper current collector. Finally, limitation solubility discussed in terms recycling. research hopefully provides guidance recycling-oriented circular economy LIB industry.
