“…It could also decrease the Li + /Ni 2+ mixing that lower the activation barrier of Li ion mobility in the layered structure. Moreover, the Na addition in layered structure could expand internal space, improved kinetic charge transfer reaction, and diffusion of Li ion transport during charging/discharging [20,21]. It is noticeable that the coulombic efficiency of NLNCM synthesized at 800 and 900 o C is 91%, which is enhanced as compared with CP-method.…”

“…[55] He et al prepared Na-stabilized Li 1.2−x Na x [Co 0.13 Ni 0.13 Mn 0.54 ]O 2 by a polymer pyrolysis method, which exhibited a Coulombic efficiency of 87%. [56] Tarascon and co-workers have demonstrated the reduction in the irreversible capacity in a model material, Li 2 RuO 3 by Sn doping. [33] The large Sn 4+ ions resist TM migration, and Ru 4+ promotes reversible oxide-ion oxidation, thereby reducing the oxygen loss and vacancy formation and resulting in a low irreversible capacity.…”

CO 2 emissions. Hence, transportation dependent on electrical propulsion (electric vehicles) instead of internal combustion engines can greatly reduce the pollution caused by our transportation infrastructure. While rechargeable Li-ion batteries are the major power source for portable electronic devices such as smartphones and laptop computers, further improvements in their energy density is required in order to promote electrochemical propulsion devices that can compete with internal combustion engines. [1] The energy density of Li-ion batteries depends on the specific capacities and redox potentials of their electrode materials. Layered lithiated transition metal oxides such as LiCoO 2 , LiNi 1/2 Mn 1/2 O 2 , and LiNi 1/3 Mn 1/3 Co 1/3 O 2 ("NMC 111") were extensively studied as cathodes, which can exhibit specific capacities ≤160 mA h g −1 with an upper potential limit of 4.3 V versus Li. [2] The high cost, low thermal stability, and fast capacity fading at high current rates or during deep cycling of currently used LiCoO 2 necessitated the development of other layered cathodes, such as LiNi 1/2 Mn 1/2 O 2 , NMC 111, etc. The electrochemical performance of these layered metal oxides was recently reviewed by Yushin and coworkers. [3] Higher capacities can be extracted from layered metal oxide cathodes by cycling to upper potentials of about 4.5 V, however, driving these layered cathode materials to such high potentials enhances the structural instability and impedance growth. [4,5] Another important direction is the development of Ni-rich NCM cathode materials. As the content of Ni is higher, the specific capacity that can be extracted is higher as

Layered Li 2 MnO 3 -LiMn 1/3 Ni 1/3 Co 1/3 O 2 solid-solution cathode materials modified with SiO 2 were prepared by spray pyrolysis and their charge-discharge properties were investigated. Both the capacity and voltage fades of SiO 2 -modified Li 2 MnO 3 -LiMn 1/3 Ni 1/3 Co 1/3 O 2 during charge/discharge cycling were suppressed compared with that of the unmodified sample. It was found that the addition of SiO 2 suppressed the dissolution of manganese ions at 60°C from the results of inductively coupled plasma (ICP) emission spectroscopy. X-ray diffraction (XRD) data indicated that weak reflections corresponding to Li 2 SiO 3 appeared as the SiO 2 content increases to 5 wt%. Scanning electron microscope (SEM) studies showed that the microstructure of the particles was significantly changed by SiO 2 addition. As indicated by transmission electron microscope (TEM) analysis, Si-rich regions were seen on the Li 2 MnO 3 -LiMn 1/3 Ni 1/3 Co 1/3 O 2 primary particles. The suppression of Mn ions and the improved charge and discharge properties were correlated with the microstructural changes.
