Introduction to Nickel Rich Layered

What is/are Nickel Rich Layered?

Nickel Rich Layered - Silicon-based materials have been regarded as the most promising anodes for high-energy batteries, when combined with high- voltage/capacity nickel-rich layered cathodes. ^[1] While the mechanism by which an upper cut-off voltage affects the performances of lithium-ion batteries has been extensively studied, the effect of a lower cut-off voltage (LCV) on the cycle life and safety of lithium-ion batteries, especially nickel-rich layered oxide/graphite–SiOx batteries, is poorly understood. ^[2] With the continuous development and progress of new energy electric vehicles, high-capacity nickel-rich layered oxides are widely used in lithium-ion battery cathode materials, and their cycle performance and safety performance have also attracted more and more attention. ^[3] It is highly desirable to realize high-energy-density lithium-ion batteries consisting of nickel-rich layered oxide cathodes (Ni-rich NMC) and Si-based anodes. ^[4] However, NCA is more stable than NCM, because the structural stability of Al doped in the nickel-rich layered oxide is stronger than Mn. ^[5] This method provides a new strategy for the surface modification of nickel-rich layered cathode materials. ^[6] Although single-crystalline structure is proved to be able to withstand anisotropic lattice strain and prevent cracks formation, the long cycle stability at high-voltage in all-solid-state batteries (ASSBs) with nickel-rich layered oxides as the cathode are still far from commercial applications. ^[7] Trace doping is an efficient way to improve the stability of nickel-rich layered cathodes for lithium-ion batteries, but the structural origin of such improvement, rather than a simple replacement, has been rarely explored. ^[8] The thermal instability is a major problem in high-energy nickel-rich layered cathode materials for large-scale battery application. ^[9] Nickel-rich layered oxides (LiNixCoyMn1−x−yO2) (x ≥ 0. ^[10] The purpose of this paper is to give an introduction to the related research results of nickel-rich layered cathodes in recent years and to help researchers understand the development status of this field in a timely and rapid manner. ^[11] Nickel-rich layered oxide LiNi1−x−yCoxAlyO2 (NCA) with high theoretical capacity is a promising cathode material for the next-generation high-energy batteries. ^[12] Nickel-rich layered LiNi0. ^[13] This review presents the recent modification strategies of the nickel-rich layered oxide materials. ^[14] Nickel-rich layered cathode materials have drawn a lot of attention due to their much higher energy density and lower cost. ^[15] This dual-conductive coating provides a viable strategy for promoting the performance and applicability for nickel-rich layered cathode materials. ^[16] Nickel-rich layered lithium metal oxides have been on the spotlight for their being advanced cathode materials for lithium-ion batteries; however, their poor cycling performance at high temperature is a critical bottleneck in their application. ^[17] Nickel-rich layered oxides (LiNi1-x-yCoxMnyO2; (1 - x - y) ≥ 0. ^[18] At the same time, the electrolyte additive, tris(trimethylsilyl) phosphite (TTMSP), has shown to improve the electrochemical performance of nickel-rich layered cathodes, such as LiNi0. ^[19] Nickel-rich layered metal oxide LiNi1–y–zMnyCozO2 (1 – y – z ≥ 0. ^[20] Nickel-rich layered oxides, such as LiNi0. ^[21] The detrimental effects on the electrochemical performances of high-capacity nickel-rich layered oxide cathode LiNi0. ^[22] It has been well recognized that Li2CO3 is inevitably formed at the surface of nickel rich layered compounds (NRLC) upon storage in air which is usually considered to be detrimental to the performance. ^[23]
