“…Practically, an orthorhombic LiMnO 2 cathode achieves between 180 and 222 mAh g −1 of the 285 mAh g −1 theoretical capacity. [39,40,97] This is similar to 220 mAh g −1 for monoclinic LiMnO 2 . [39] A combination of both orthorhombic and monoclinic phases, as demonstrated by Li et al, combines the high capacity of the monoclinic types with the enhanced stability of the orthorhombic type, as well as boasting the lowest impedance.…”

“…[38] This has kindled interest into binary and ternary materials that entirely or partially substitute Co. These include LiMnO 2 , [39][40][41] LiCoMnO 2 , [42,43] and LiMnNiO 2 . [44][45][46] The advantage of Mn inclusion is that it generally has less resistance due to the formation of spinel phases, while Ni provides high energy density.…”

“…Exploiting this method, Tong [87] Copyright 2014, Springer Nature. et al fabricated a mesoporous LiMnO 2 cathode that obtained a discharge capacity of 191 mAh g −1 , 85.0% of which was retained over 50 cycles at 0.5C in the range of 2.0-4.4 V. [40] Cho et al showed that the capacity retention can be improved to 98.0% over 50 cycles using an Al 2 O 3 coating, which demonstrated no initial deterioration in its initial capacity, a property reportedly observed in metal oxide coatings, but this causes a low capacity of 30.0 mAh g −1 . [98] Cho et al reported the improvement in capacity retention of the LiCoO 2 by sputtering a 10 nm thick layer atop a LiCoO 2 thin film upon a platinum current collector.…”

“…[65] The capacity retention of 85.0% for NaMnO 2 in this instance is comparable to LiMnO 2 in a Li + battery at 84.9% over 50 cycles. [40,65] Additionally, Zhang et al synthesized NaMnO 2 that exists as a mix of monoclinic NaMnO 2 and P2-NaMnO 2 , which results in a first discharge capacity of 195.6 mAh g −1 . However, this highlights the persisting stability issues as the capacity retention is only 52.0% over 30 cycles.…”

Early LiCoO 2 research provided the basis for the tremendous commercial success of Li + batteries since their invention in the early 1990s. Today, LiN-iMnCoO 2 (Li-NMC) is one of the most widely used batteries in the rapidly evolving electronic vehicle industry. Li-NMC batteries continue to receive significant interest as research efforts aim to partially, or entirely, replace the use of scarcely available and toxic Co with elemental doping to form binary, ternary, and quaternary layered oxides. Furthermore, safety concerns and rising uncertainty for the future of Li supplies have resulted in growing curiosity toward non-Li + rechargeable batteries such as Na + and K + . Unfortunately, the success of Li + host materials does not always directly transfer to Na + and K + batteries due to the difficulty of reversibly intercalating larger ions without irreparably distorting the host structure. Consequently, this report provides an overview of the Li-based materials surrounding the success of commercial Li-NMC and the subsequent progress of their lesser studied Na and K counterparts. The challenges for current cathode materials are highlighted, and the opportunities for progression are suggested. The summary presented in this review can be consulted to steer new and unique research avenues for layered oxide materials as metal-ion battery cathodes.

“…where AM is the active material and eis an electron. The most common LIBs use different metal oxides, such as LiFePO 4 [24], LiCoO 2 [25], or LiMnO 2 [26], as active materials for the cathodes. The selection of the active material is dependent on the specific application, as each one allows for different operational voltage [27].…”

Environmental issues related to energy consumption are mainly associated with the strong dependence on fossil fuels. To solve these issues, renewable energy sources systems have been developed as well as advanced energy storage systems. Batteries are the main storage system related to mobility, and they are applied in devices such as laptops, cell phones, and electric vehicles. Lithium-ion batteries (LIBs) are the most used battery system based on their high specific capacity, long cycle life, and no memory effects. This rapidly evolving field urges for a systematic comparative compilation of the most recent developments on battery technology in order to keep up with the growing number of materials, strategies, and battery performance data, allowing the design of future developments in the field. Thus, this review focuses on the different materials recently developed for the different battery components—anode, cathode, and separator/electrolyte—in order to further improve LIB systems. Moreover, solid polymer electrolytes (SPE) for LIBs are also highlighted. Together with the study of new advanced materials, materials modification by doping or synthesis, the combination of different materials, fillers addition, size manipulation, or the use of high ionic conductor materials are also presented as effective methods to enhance the electrochemical properties of LIBs. Finally, it is also shown that the development of advanced materials is not only focused on improving efficiency but also on the application of more environmentally friendly materials.

Recent Advances in Enhanced Performance of Ni‐Rich Cathode Materials for Li‐Ion Batteries: A Review

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.
