Lattice Reconstruction and Surface Engineering Enable High‐Voltage Operation of Regenerated LiCoO 2 Cathodes
Efficient recycling and high‐value regeneration of spent LiCoO 2 (LCO) cathodes are important for advancing lithium‐ion batteries (LIBs) recycling and promoting the sustainable utilization of critical resources. Here, we identify the intrinsic factors limiting the structural recovery of spent LCO (SLCO) and demon...
