      abstract     = {In this study, self-prepared nanostructured CuO electrodes
                      show no capacity decay for 40 cycles at 0.1C in Li metal
                      cells. The reaction mechanisms of the CuO electrodes are
                      investigated. With the help of in situ EIS, in situ XRD,
                      TEM, XAS, SQUID, IC and GC-MS, it is found that the
                      as-prepared CuO electrode undergoes significant phase and
                      composition changes during the initial lithiation, with the
                      transformation of CuO to nano-crystalline Cu. During the 1st
                      delithiation, Cu is inhomogeneously oxidized, which yields a
                      mixture of Cu2O, Cu2−xO and Cu. The incomplete conversion
                      reaction during the 1st cycle is accompanied by the
                      formation and partial decomposition of the solid electrolyte
                      interphase (SEI) as the side reactions. Nevertheless, from
                      the 1st to the 5th delithiation, the oxidation state of Cu
                      approaches +2. After an additional formation step, the
                      transformation to Cu and back to Cu2−xO remains stable
                      during the subsequent long-term cycling with no electrolyte
                      decomposition products detected. The LiNi1/3Mn1/3Co1/3O2
                      (NMC-111)/CuO full cells show high capacities (655.8 ± 0.6,
                      618.6 ± 0.9 and 290 ± 2 mA h g−1 at 0.1, 1 and 10C,
                      respectively), within the voltage range of 0.7–4.0 V at 20
                      °C and a high capacity retention $(85\%$ after 200 cycles
                      at 1C).},
