“…As for the conventional LIBs using LEs, the layered or spinel Li x MO 2 (M=Co, Ni, Mn) cathode materials are considered as viable candidates for ASLBs because of their highly reversible intercalation‐deintercalation reaction with low dimensional change and high operating potential. To date, many Li x MO 2 materials, including LiCoO 2 ,3a,5a,9,14d,23b,c,32,36,41,42 Li[Ni,Mn,Co]O 2 ,42ae,43 and LiMn 2 O 4 ,42aa have been tested in ASLBs using sulfide SEs. However, the bare Li x MO 2 showed much lower capacity than the theoretical one, a large amount of irreversible reaction during charging, and a high overpotential, shown in Figure 6 42h.…”
