“…As Figure 7B,C shows, the Nyquist curves of the pristine NCM and M-NCM display a similar outline with the The semicircle now appears as a combination of two semicircles. 40 As such, the one at the high-frequency region refers to the resistance of the SEI layer (R SEI ) and the other at the middle-frequency region corresponds to the chargetransfer resistance (R ct ). The oblique line at the lowfrequency region represents the Warburg impedance (W).…”

Summary The structural and interfacial degradation of Ni‐rich cathode materials during the cycling continuously delays its commercialization of lithium‐ion batteries (LIBs). To overcome these drawbacks, we propose a MgHPO4‐modified LiNi0.8Co0.1Mn0.1O2 (M‐NCM) cathode material. From electrochemical analysis, M‐NCM takes the combining advantages of Mg doping and Li3PO4 coating. Interestingly, M‐NCM shows a better discharge capacity of 203.5 mAh g−1, delivering outstanding initial coulombic efficiency of 86.1% compared to the pristine LiNi0.8Co0.1Mn0.1O2. Additionally, M‐NCM displays advanced cycle performance with a superior capacity retention of 81.1% after 100 cycles. Furthermore, M‐NCM effectively suppresses interfacial undesirable reactions at electrode/electrolyte interface during cycling. Consequentially, this study finds that MgHPO4 surface modification can bring enhanced electrochemical performance of Ni‐rich‐layered cathode materials for high‐energy and long‐term LIBs.

High energy Li‐ion batteries (LIBs) have garnered substantial consideration in recent years for their utilization in many fields like communication, transportation, and aviation. As the cathode is the crucial component of LIBs, so by enhancing its electrochemical performance, the capacity, rate capability, as well as cyclability of batteries can be enhanced. Ni‐rich cathode materials (LiNi x Mn y Co1−x−y O2, x ≥ 0.5) have been accredited for their benefits in enhanced capacity, high working voltage, and low manufacturing cost. The high Ni content is accountable for the exceptional capacity but the utilization in the commercialized LIBs is mired by their electrochemical cycling issues like capacity fading, voltage decay, and safety hazard. To overcome these obstructions, a variety of methodologies have been adopted like doping, coating, and comodification of these cathode materials. An inclusive study of Ni‐rich cathode materials, their degradation mechanism, and the strategies is conferred, which have been employed in recent years to overcome the challenges faced by these materials in their commercialization.

“…Among the various cathode materials, layered transition metal oxides LiNi 1−x−y Mn x Co y O 2 (NMC) have attracted wide attention. Compared with LiCoO 2 , LiMn 2 O 4 , and LiNiO 2 , NMC materials have excellent electrochemical properties, such as high energy density, high reversibility, good environmental compatibility, and an excellent charge-discharge rate [5][6][7][8][9][10][11][12][13]. In previous studies, these electrochemical properties of NMC materials have been investigated for different transition metal (TM) ratios, including LiNi 1/3 Mn 1/3 Co 1/3 O 2 (333) [8], LiNi 0.4 Mn 0.4 Co 0.2 O 2 (442) [9], LiNi 0.5 Mn 0.3 Co 0.2 O 2 (532) [10], LiNi 0.6 Mn 0.2 Co 0.2 O 2 (622) [11], LiNi 0.7 Mn 0.15 Co 0.15 O 2 (71515), [12] and LiNi 0.8 Mn 0.1 Co 0.1 O 2 (811) [13].…”

LiNi1−x−yMnxCoyO2 materials are a typical class of layered cathode materials with excellent electrochemical performance in lithium-ion batteries. Molecular dynamics simulations are performed for LiNi1−x−yMnxCoyO2 materials with different transition metal ratios. The Li/Ni exchange ratio, ratio of anti-site Ni2+ to total Ni2+, and diffusion coefficient of Li ions in these materials are calculated. The results show that the Li-ion diffusion coefficient strongly depends on the ratio of anti-site Ni2+ to total Ni2+ because their variation tendencies are similar. In addition, the local coordination structure of the Li/Ni anti-site is analyzed.
