Abstract:Lithium‐ion batteries (LiBs) are widely used in various applications because of their high energy density, low self‐discharge rate, and portability. The requirements for LiBs continue to increase drastically every year; however, the disposal of spent LIBs is a cumbersome task. To resolve this issue, spent LiB anodes are customized into high‐performance supercapacitor (SC) electrodes via supercritical water exfoliation. The specific capacitance of spent LiB anodes (289 F g−1 at 2 A g−1) significantly improved a… Show more
