“…31 Moreover, in an attempt to enlarge the electrochemical stability window of the electrolyte and enable the investigation of the Ni redox activity at higher potential values, an ionic liquid-based electrolyte, that is, NaTFSI in Py 13 FSI (1:9 in mole ratio), was employed. 32,33 A comparative electrochemical investigation between the carbon-coated Na 4 Ni 3 (PO 4 ) 2 (P 2 O 7 ) and Na 2 NiP 2 O 7 is shown in Figure 3, showing the differential capacity vs voltage (dQ/dV) curves of Na 4 Ni 3 (PO 4 ) 2 (P 2 O 7 )/C and Na 2 Ni(P 2 O 7 )/C.…”

Although nickel-based polyanionic compounds are expected to exhibit a high operating voltage for batteries based on the Ni 2+/3+ redox couple activity, some rare experimental studies on the electrochemical performance of these materials are reported, resulting from the poor kinetics of the bulk materials in both Li and Na nonaqueous systems. Herein, the electrochemical activity of the Ni 2+/3+ redox couple in the mixed-polyanionic framework Na 4 Ni 3 (PO 4 ) 2 (P 2 O 7 ) is reported for the first time. This novel material exhibits a remarkably high operating voltage when cycled in sodium cells in both carbonate-and ionic liquid-based electrolytes. The application of a carbon coating and the use of an ionic liquid-based electrolyte enable the reversible sodium ion (de-)insertion in the host structure accompanied by the redox activity of Ni 2+/3+ at operating voltages as high as 4.8 V vs Na/Na + . These results present the realization of Ni-based mixed polyanionic compounds with improved electrochemical activity and pave the way for the discovery of new Na-based high potential cathode materials.

In addition, recent concerns over the cost and future availability of lithium highlight the urgent need to exploit alternative energy storage systems. 3 In these terms, sodium (Na)-ion batteries are attractive candidates because of the electrochemistry that is similar to the well-established lithium-ion technology. 4 To date, the LiFePO 4 olivine with (PO 4 ) 3 − polyanionic framework, owing to its superior thermal stability and low cost, is considered to be one of the best electrode materials for lithium-ion batteries, mostly in view of its stable operating voltage and satisfactory specific capacity. However, the intrinsic tunability of the operating voltage of polyanionic compounds because of the presence of different transition metals such as Mn, Co and Ni 5-7 has triggered interest in alternative frameworks exhibiting higher cell voltages. According to theoretical prediction, lithium nickel phosphate has a remarkably high working potential (~5.1 V vs Li + /Li) because of the Ni 2+/3+ redox activity. 8 Unfortunately, several studies have demonstrated that the implementation of this material is restricted by several drawbacks such as the intrinsic sluggish kinetics attributable to the low electronic conductivity, the poor lithium transport in commonly used electrolyte systems and the structural

“…LFP's olivine framework enables rapid Li + transport [377], and is stabilised by the electron-withdrawing nature of the PO4 3-polyanion. The strong P-O covalent bond reduces the relative strength of the covalent interaction to the neighbouring Fe, thus lowering the Fe 4+/3+ redox couple energy and providing stable operating voltages of ~3.5 V, with good reversibility [378]. LFP electrodes are also relatively inexpensive to prepare, non-toxic and environmentally benign, all factors which have become increasingly important over recent years.…”

“…One such example is LiMnPO4 [447][448][449][450][451][452][453][454][455][456][457][458], which is isostructural to that of olivine LiFePO4, while possessing a higher operating voltage (4.1 vs. 3.5 V, respectively) [378,448], and hence energy densities which could exceed 700 Wh kg -1 . At this point, it should be suggested that LiMnPO4 represents a more realistic candidate compared to LiCoPO4 or LiNiPO4, since the working voltage of LiCoPO4 or LiNiPO4 electrodes (4.9 and 5.1 V, respectively), currently lies outside regions of stability of the commonly-employed organic (carbonate) electrolytes [378]. Early examples of LiMnPO4 electrodes, however, were unable to demonstrate appreciable electrochemical activity [373], until a solid-state reaction involving the addition of carbon black to the reactant mixture enabled a capacity of 140 mA h g -1 to be extracted [448].…”

Rights © Tsinghua University Press and Springer-Verlag Berlin ABSTRACTThe performance of the lithium-ion cell is heavily dependent on the ability of the host electrodes to accommodate and release Li + ions from the local structure. While the choice of electrode materials may define parameters such as cell potential and capacity, the process of intercalation may be physically limited by the rate of solid-state Li + diffusion. Increased diffusion rates in lithium-ion electrodes may be achieved through a reduction in the diffusion path, accomplished by a scaling of the respective electrode dimensions.In addition, some electrodes may undergo large volume changes associated with charging and discharging, the strain of which, may be better accommodated through nanostructuring. Failure of the host to accommodate such volume changes may lead to pulverisation of the local structure and a rapid loss of capacity. In this review article, we seek to highlight a number of significant gains in the development of nanostructured lithium-ion battery architectures (both anode and cathode), as drivers of potential next-generation electrochemical energy storage devices.

and demand in terms of time and space. Thus, grid-level stationary energy storage systems (ESSs) play a key role in making renewable energies both effective and efficient and thereby shaping a more sustainable and environmental friendly society.Although different energy storage technologies including mechanical, electrical, chemical, and electrochemical systems have been proposed, [2,3] mechanical energy storage through pumped hydroelectricity currently dominates the market (≈95% of the installed capacity, ≈183 GW). [4] Electrochemical energy storage is also being considered as a promising option for ESSs based on its flexibility of deployment with little restriction on size and geographical location, low maintenance costs, large energy density, high round-trip efficiency, and long cycle life. [3,5,6] The market for Li-ion batteries (LIBs), originally commercialized for portable electronic devices (i.e., cell phones and laptops), is now expanding to electric vehicles (EVs) and gridlevel ESSs. However, it remains debatable whether the global Li reserves, ≈14 million tons, can meet the increasing demand for such large-scale applications. [7][8][9] The price of lithium carbonate, which is a primary precursor for LIBs, has been continuously increasing since 2000, [10] and this trend is likely to accelerate once the EV and ESS markets take off. Moreover, Li is geographically limited to specific regions: ≈86% of the Li reserves are located in Bolivia, Chile, China, Argentina, and Australia; [9] therefore, geopolitical issues may arise. A more pressing issue for Li-ion markets is the use of Co in all high-energy-density systems. With more than 50% of all mined Co destined for use in Li-ion technology, and a substantial fraction of that coming from the Democratic Republic of the Congo, Li-ion growth may be hampered by the availability of Co. [11] As a less expensive alternative to LIBs, Na-ion batteries (NIBs) have been extensively studied. [6,[12][13][14] The relatively high standard redox potential of Na/Na + leads to a lower working voltage and thereby lower energy density than Li-ion. In addition, hard carbon, which is associated with a high production cost and low material's density, must be used as an anode in NIBs, as graphite, which is the standard anode for LIBs, cannot store Na ions. [15][16][17] Recently, K-ion batteries (KIBs) have emerged as another possible energy storage system. [18][19][20] It is notable that the abundance of K resources in the Earth's crust and oceans is similar to that of Na (Figure 1a). [21,22] The cost of potassium carbonate The development of rechargeable batteries using K ions as charge carriers has recently attracted considerable attention in the search for cost-effective and large-scale energy storage systems. In light of this trend, various materials for positive and negative electrodes are proposed and evaluated for application in K-ion batteries. Here, a comprehensive review of ongoing materials research on nonaqueous K-ion batteries is offered. Information on the status of ...
