Direct upcycling of spent layered oxide cathodes <i>via</i> a dual-functional eutectic salt for sodium-ion batteries

Using Na 2 CO 3 –K 2 CO 3 eutectic system enables simultaneous resodiation and K + -doping, forming a low-melting phase for complete surface reconstruction. K + incorporation expands interlayer spacing, improving Na + transport kinetics.
