Mn–Ni Content-Dependent Structures and Electrochemical Behaviors of Serial Li1.2Ni0.13+xCo0.13Mn0.54–xO2 as Lithium-Ion Battery Cathodes

“…Aside from these, a so-called optimization of chemical composition has also been recognized as an effective route to improve the electrochemical performance of solid solutions. For example, the variation of elemental content for the formulas of Li[Li x Ni 0.34– x Mn 0.47 Co 0.19 ]O 2 , Li 1+ x Mn 0.5+0.5 x Ni 0.5–0.5 x O 2 , Li 1+ n [Ni m Co m Mn 1–2 m ]O 2 , and y Li 2 MnO 3 ·(1 – y )LiNi 1/3 Co 1/3 Mn 1/3 O 2 could exert a great influence on the electrochemical properties of corresponding electrodes. Among all the solid solutions, Li 1.2 Ni 0.13 Co 0.13 Mn 0.54 O 2 (i.e., 0.5Li 2 MnO 3 ·0.5LiNi 1/3 Co 1/3 Mn 1/3 O 2 ) has been proved as one of the most promising cathode materials due to its high discharge capacity, moderate cycling performance, and good rate capability. − …”

LaPO4-coated Li1.2Mn0.56Ni0.16Co0.08O2 as a cathode material with enhanced coulombic efficiency and rate capability for lithium ion batteries

“…35,37 The electrochemical inactive Li 2 MnO 3 region became active mainly due to the removing of Li 2 O from the lattice and forming of [MnO 2 ]. 21,38 As reported by many literature, the surface modication could reduce the activity of extracted oxygen, enhancing the reversible prosperities for lithium rich layered oxides cathodes. 39,40 As shown in Fig.…”

Template GNL-assisted synthesis of porous Li1.2Mn0.534Ni0.133Co0.133O2: towards high performance cathodes for lithium ion batteries

“…11 Besides, the weak reections around 21 (marked with dashed line circles in Fig. 1) correspond to the integrated monoclinic Li 2 MnO 3 character (space group C2/m), 32 originating from the super lattice ordering of the Li, Mn, Ni, and Co in the 3a site. No obvious diffraction peak assignable to any impurity phase is detected from the XRD patterns, indicating the successful formation of highly puri-ed oxides.…”
