Upcycling Spent LiCoO 2 Cathodes via Surface Spinel Reconstruction for Efficient Furfural Hydrogenation

Spent lithium‐ion batteries represent a growing environmental challenge, yet their transition‐metal‐rich cathodes remain largely underutilized as functional materials. We report a direct upcycling strategy in which LiCoO 2 cathodes recovered from end‐of‐life smartphones are trans...
