      abstract     = {As promising cathode materials, the lithium‐excess
                      3d‐transition‐metal layered oxides can deliver much
                      higher capacities (>250 mAh g−1 at 0.1 C) than the current
                      commercial layered oxide materials (≈180 mAh g−1 at 0.1
                      C) used in lithium ion batteries. Unfortunately, the
                      original formation mechanism of these layered oxides during
                      synthesis is not completely elucidated, that is, how is
                      lithium and oxygen inserted into the matrix structure of the
                      precursor during lithiation reaction? Here, a promising and
                      practical method, a coprecipitation route followed by a
                      microwave heating process, for controllable synthesis of
                      cobalt‐free lithium‐excess layered compounds is
                      reported. A series of the consistent results unambiguously
                      confirms that oxygen atoms are successively incorporated
                      into the precursor obtained by a coprecipitation process to
                      maintain electroneutrality and to provide the coordination
                      sites for inserted Li ions and transition metal cations via
                      a high‐temperature lithiation. It is found that the
                      electrochemical performances of the cathode materials are
                      strongly related to the phase composition and preparation
                      procedure. The monoclinic layered Li[Li0.2Ni0.2Mn0.6]O2
                      cathode materials with state‐of‐the‐art
                      electrochemical performance and comparably high discharge
                      capacities of 171 mAh g−1 at 10 C are obtained by
                      microwave annealing at 750 °C for 2 h.},
