“…In addition, the plateau at 2.25 V can be explained as the electrochemical reaction of the Mn 3+ /Mn 4+ redox couple. 6,10,13,20 Each plateau at 3.2 and 3.62 V can be attributed to the different staging of the sodium layers. The plateaus at 4.17 V can account for the P2-O2 phase transformation, which take places at low sodium content to reduce the repulsion of the oxygen electronic shells in the trigonal prismatic coordination.…”

“…Since 2010, their electrochemical properties, such as specific capacity, cycle life, and c-rate capability, have been investigated to determine the relationship between cathode structure and electrochemical performance. [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] Among various Na x MO 2 -type candidates, P-type Na x MO 2 materials have shown a higher capacity and longer cycle life than O-type materials due to the better sodium ion diffusivity in trigonal prismatic (P) rather than octahedral (O) environments. As a result, more reports on P2-type cathodes have been published.…”

Unstable and deficient supplies of lithium resources have led to the development of alternative battery systems such as sodium-ion batteries. Herein, P-type Na0.6Mn0.65Ni0.25Co0.10O2 cathode materials were synthesized by a co-precipitation and solid-state reaction method. When the calcination temperature was changed from 700 to 1000°C, Na0.6Mn0.65Ni0.25Co0.10O2 had a different morphology and crystalline structure; however, a P3-type structure was formed only at 700°C, and P2-type structured cathodes could be obtained at 800, 900, and 1000°C. Their electrochemical performances were evaluated with 2032 coin-type half cells. Among them, the P2-type cathode calcinated at 900°C, exhibited a high specific discharge capacity of 148 mAh g−1, and a stable cycling performance at a 0.2 C rate for 150 cycles.

Sodium equivalents of lithiumcontaining electrode materials, such as oxides, sulfi des, phosphates, pyrophosphates, fl uorophosphates, and alloying metals, have been evaluated as electrode materials for SIBs. [1][2][3][4][5][6] Among the positive electrode materials for SIBs, layered oxides (NaTMO 2 , TM = transition metals) are most attractive due to their large capacity, simple synthesis, and structural stability. [7][8][9][10][11][12][13][14] Various transition metal elements can be substituted into the layered structure, similar to layered lithium compounds, and this will infl uence the structural stability of sodium-ion removal, operating voltage, capacity, and cyclability. In contrast to lithium systems, different stacking structures for Na layered oxides can be examined because of the preferred prismatic coordination of the larger sodium ions. Positive electrode materials with a P2 layered structure by Delmas' notation [ 15 ] have better cyclability and structural stability during electrochemical reactions than those with an O3 layered structure. [ 16 ] The trigonal prismatic site is more favorable for the diffusion of sodium ions, [17][18][19][20] and the diffusion kinetics for Na + can thus be more effi cient in the P2 layered structure compared to those in the O3 layered structure, which is common in lithium intercalation compounds. P2 layered materials with various transition metal compositions for SIBs have been studied, such as Mn-Co, Ni-Mn, and Fe-Mn. [ 9,17,[21][22][23][24][25] Moreover, several approaches for the doping of two-component P2 layered materials with transition metals have also been introduced, [ 8 ] including Co doping on Ni-Mn compounds, [ 26,27 ] Ni doping on Co-Mn systems, [ 28,29 ] and Ni doping on Fe-Mn system. [ 30 ] However, few studies on the Fe-Mn-Co system with P2 stacking have been reported compared to Ni-Fe-Mn or Ni-Co-Mn P2 materials. [ 31,32 ] Co can facilitate the oxidation of Fe atoms, as reported in Li compounds, [ 33 ] and Co can likely stabilize the oxidized state in the layered structure, especially for Fe-containing layered materials. [ 34 ] In addition, Wang et al. reported that Co suppresses the irreversibility of P2-Na 2/3 Mn y Co 1− y O 2 materials. [ 23 ] A similar behavior in the P2-Na-Fe-Co-Mn oxides would be expected.In this paper, P2-Na 0.7 [(Fe 0.5 Mn 0.5 ) 1− x Co x ]O 2 ( x = 0, 0.05, 0.10, and 0.20) was synthesized by a solid-state reaction, and the electrochemical performance of the P2-Fe-Mn-Co system Sodium layered oxides with mixed transition metals have received signifi cant attention as positive electrode candidates for sodium-ion batteries because of their high reversible capacity. The phase transformations of layered compounds during electrochemical reactions are a pivotal feature for understanding the relationship between layered structures and electrochemical properties. A combination of in situ diffraction and ex situ X-ray absorption spectroscopy reveals the phase t...

sources into large-scale grids, inexpensive, efficient, and fast-responding electrical energy storage (EES) systems are essential to store the off-peak energy and releasing the stored energy during the onpeak period. Among various EES systems, rechargeable batteries represent one of the most competitive technologies because of their high conversion efficiency and environmental friendliness. [1][2][3][4] For stationary EES systems, batteries with low cost, high safety, high rate capability, and long cycle stability are highly desired.Lithium (Li)-ion batteries (LIBs) have achieved great success in the market of portable electronics and electric vehicles since their commercialization by Sony Company in 1991. However, the shortage of Li resources in nature gives rise to a concern about its sustainable development in grid scale. Compared with Li, sodium resource has rich natural abundance in the earth crust and a worldwide distribution, consequently leading to a low price of sodium-based raw materials (e.g., the cost of Na 2 CO 3 is about 25-30 times lower than that of Li 2 CO 3 ). Besides, sodium has a suitable redox potential (E 0 (Na + /Na) = −2.71 V versus standard hydrogen electrode (SHE), 0.3 V above that of Li + /Li) and similar physical and chemical properties with lithium. [5,6] Therefore, rechargeable sodium-ion batteries (SIBs), which have a similar "rockingchair" working principle of LIBs, are emerging as an appealing choice as alternatives for LIBs. Note that it is difficult for SIBs to bypass LIBs in terms of energy densities because of the much higher weight of Na and lower standard electrochemical potential. [7][8][9][10] Nevertheless, the use of low-cost materials, including inexpensive Na-based raw materials and Al current collectors for both cathodes and anodes in SIBs, could significantly reduce the cost. In this case, SIBs could be applied where cost-effectiveness rather than energy density is the most critical issue, e.g., in the field of large-scale EES. As a result, sodiumbased electroactive materials are enjoying renewed interest especially for very low cost systems for grid storage. [11,12] Given that cathode materials are the key component that determines energy density and cost, tremendous efforts have been devoted to exploring suitable positive electrode materials with high reversible capacity, rapid Na ions insertion/extraction, and good cycling stability in the past few years. [13,14] A broad range of compounds, including layered oxides, polyanionic frameworks, hexacyanoferrates, and organics, haveThe increasing demand for replacing conventional fossil fuels with clean energy or economical and sustainable energy storage drives better battery research today. Sodium-ion batteries (SIBs) are considered as a promising alternative for grid-scale storage applications due to their similar "rockingchair" sodium storage mechanism to lithium-ion batteries, the natural abundance, and the low cost of Na resources. Searching for appropriate electrode materials with acceptable electrochemical perfor...
