“…10 We have established that 2 nm coated NCA electrodes (NCA/LAO-2) demonstrated ∼2-3 times lower capacity fading compared to that of bare and 0.5 nm and 1 nm coated ones, as shown in Figure 8. Our findings are in agreement with the literature data, [53][54][55] in which the authors demonstrated that coatings increase the voltage window and improve cycling performance of battery materials, like LiCoO 2 if powders or composite electrodes were coated with various thin coatings by ALD. These coatings serve as a thin film with low interfacial resistance on the cathode surface, suppress side reactions and electrolyte decomposition mainly at high potentials, prevent the deterioration of cathode structure, resulting therefore in enhanced cyclic stability and low self-discharge.…”

“…These coatings serve as a thin film with low interfacial resistance on the cathode surface, suppress side reactions and electrolyte decomposition mainly at high potentials, prevent the deterioration of cathode structure, resulting therefore in enhanced cyclic stability and low self-discharge. 54 The effectiveness of the LiAlO 2 coated NCA-electrodes in terms of more stable cycling and lower capacity fade was confirmed by analysis of impedance measurements represented in Figure 9. We demonstrate impedance spectra of bare and NCA/LAO-2 electrodes measured at several open-circuit potentials during charge (Li + deintercalation), up to 4.5 V. Usually, these spectra for practical porous intercalation electrodes consist of two (or sometimes three) semicircles at high (10 5 -10 4 Hz) and intermediate (10 3 -10 2 Hz) frequencies, respectively and a slope line at very low frequencies (a few mHz range); the latter is attributed to the Li + solid state diffusion (Warburg element).…”

“…24 One of the efficient processes for coating is atomic layer deposition (ALD) that was shown to be an alternative technique with several important advantages over the others. [27][28][29] For instance, the coating thickness can be tailored just by the number of ALD cycles and furthermore the coating is uniform amongst all secondary particles. Consequently, improvements in the capacity retention, the rate capability and the Journal of The Electrochemical Society, 164 (13) A3266-A3275 (2017) A3267 electrochemical behavior at high temperature can be achieved.…”

In this paper, we studied the influence of LiAlO 2 coatings of 0.5, 1 and 2 nm thickness prepared by Atomic Layer Deposition onto LiNi 0.8 Co 0.15 Al 0.05 O 2 electrodes, on their electrochemical behavior at 30 and 60 • C. It was demonstrated that upon cycling, 2 nm LiAlO 2 coated electrodes displayed ∼3 times lower capacity fading and lower voltage hysteresis comparing to bare electrodes. We established a correlation among the thickness of the LiAlO 2 coating and parameters of the self-discharge processes at 30 and 60 • C. Significant results on the elevated temperature cycling and aging of bare and LiAlO 2 coated electrodes at 4.3 V were obtained and analyzed for the first time. By analyzing of X-ray diffraction patterns of bare and 2 nm coated LiNi 0.8 Co 0.15 Al 0.05 O 2 electrodes after cycling, we concluded that cycled materials preserved their original structure described by R-3m space group and no additional phases were detected. The lithium-ion batteries (LIB) market nowadays has expanded widely from cellular phones, computers and other electronic devices to the automotive industry. Positive electrodes for LIBs to be explored in electric vehicles are mainly based on lithiated transition-metal oxides comprising Ni, Co and Mn (LiNi y Co x Mn 1-y-x O 2 ) and designated as NCM.1,2 They have attracted much attention as promising materials and therefore many research projects have been dedicated to them in the past 20 years. [3][4][5][6][7][8][9][10][11][12][13] In studies of LiNi 1/3 Co 1/3 Mn 1/3 O 2 (NCM333) cathodes, it was demonstrated 4-6 that they provided a capacity of 200 mAh/g in the voltage range of 2.5-4.6 V, or ∼155 mAh/g if the cutoff voltage is limited by 4.3 V.7 A substantially improved high-voltage performance of NCM333 electrodes (up to 4.6 V) was achieved by introducing tris(2,2,2-trifluoroethyl) borate additive in the electrolyte solution.8 These authors suggest that the additive takes part in the formation of the solid-electrolyte interface by lowering and stabilization of the interfacial resistance. NCM333 and NCM424 materials were studied in our group from the viewpoint of their electrochemical behavior, aging mechanisms, thermal properties, and surface chemistry developed upon cycling in ethylene carbonate-dimethyl carbonate/LiPF 6 based solutions.9 LiNi y Co x Mn 1-y-x O 2 materials with higher Ni content (y > 5) are important due to high capacity that can be extracted by charging up to 4.3 V only. However, Ni-rich NCMs suffer from their low cycling stability especially for compositions with Ni ≥ 60%, severe capacity fading and impedance increase during cycling at elevated temperatures (e.g. 45• C). One of the effective ways to stabilize the structure of NCM materials, to increase cycling activity and to diminish the heat evolution of the electrodes in a charged 14 There is a consensus in the literature that the above drawbacks originate from the unstable Ni 4+ ions developed in the charge state (high anodic potential, most Li + extracted from NCA). These Ni-ions can be readily reduce...

“…While this approach is fairly easy to perform, the coatings often suffer from cracks or are deposited as flakes. Recently, powder atomic layer deposition (pALD) was shown to be an alternative technique with several benefits [109]. The coating thickness can be tailored just by the number of pALD cycles and, furthermore, the coating is uniform amongst all secondary particles.…”

Amongst a number of different cathode materials, the layered nickel-rich LiNi y Co x Mn 1−y−x O 2 and the integrated lithium-rich xLi 2 MnO 3 ·(1 − x)Li[Ni a Co b Mn c ]O 2 (a + b + c = 1) have received considerable attention over the last decade due to their high capacities of~195 and~250 mAh·g −1 , respectively. Both materials are believed to play a vital role in the development of future electric vehicles, which makes them highly attractive for researchers from academia and industry alike. The review at hand deals with both cathode materials and highlights recent achievements to enhance capacity stability, voltage stability, and rate capability, etc. The focus of this paper is on novel strategies and established methods such as coatings and dopings.

For the first time, atomic layer deposition (ALD) of Al2 O3 was adopted to enhance the cyclic stability of layered P2-type Na2/3 (Mn0.54 Ni0.13 Co0.13 )O2 (MNC) cathodes for use in sodium-ion batteries (SIBs). Discharge capacities of approximately 120, 123, 113, and 105 mA h g(-1) were obtained for the pristine electrode and electrodes coated with 2, 5, and 10 ALD cycles, respectively. All electrodes were cycled at the 1C discharge current rate for voltages between 2 and 4.5 V in 1 M NaClO4 electrolyte. Among the electrodes tested, the Al2 O3 coating from 2 ALD cycles (MNC-2) exhibited the best electrochemical stability and rate capability, whereas the electrode coated by 10 ALD cycles (MNC-10) displayed the highest columbic efficiency (CE), which exceeded 97 % after 100 cycles. The enhanced electrochemical stability observed for ALD-coated electrodes could be a result of the protection effects and high band-gap energy (Eg =9.00 eV) of the Al2 O3 coating layer. Additionally, the metal-oxide coating provides structural stability against mechanical stresses occurring during the cycling process. The capacity, cyclic stability, and rate performance achieved for the MNC electrode coated with 2 ALD cycles of Al2 O3 reveal the best results for SIBs. This study provides a promising route toward increasing the stability and CE of electrode materials for SIB application.
