“…The olivine LiMPO 4 materials (M=Mn, Fe, Co, Ni) have emerged as a promising class of cathode materials for Li-ion batteries. 4,[44][45][46][47] In particular, LiFePO 4 has already found widespread application in industry. Though primarily investigated for Li-ion battery cathode applications, there have been a few investigations into the Na-equivalents for potential Na-ion battery and other applications.…”

To evaluate the potential of Na-ion batteries, we contrast in this work the difference between Na-ion and Li-ion based intercalation chemistries in terms of three key battery properties -voltage, phase stability and diffusion barriers. The compounds investigated comprise the layered AMO 2 and AMS 2 structures, the olivine and maricite AMPO 4 structures, and the NA-SICON A 3 V 2 (PO 4 ) 3 structures. The calculated Na voltages for the compounds investigated are 0.18-0.57 V lower than that of the corresponding Li voltages, in agreement with previous experimental data. We believe the observed lower voltages for Na compounds are predominantly a cathodic effect related to the much smaller energy gain from inserting Na into the host structure compared to inserting Li. We also found a relatively strong dependence of battery properties with structural features. In general, the difference between the Na and Li voltage of the same compound, ∆V Na-Li , is less negative for the maricite structures preferred by Na, and * To whom correspondence should be addressed 1 more negative for the olivine structures preferred by Li. The layered compounds have the most negative ∆V Na-Li . In terms of phase stability, we found that open structures, such as the layered and NASICON structures that are better able to accommodate the larger Na + ion generally have both Na and Li versions of the same compound. For the close-packed AMPO 4 structures, our results show that Na generally prefers the maricite structure, while Li prefers the olivine structure, in agreement with previous experimental work. We also found surprising evidence that the barriers for Na + migration can potentially be lower than that for Li + migration in the layered structures. Overall, our findings indicate that Na-ion systems can be competitive with Li-ion systems.

“…The main benefi t of LiCoPO 4 over LiMnPO 4 is its high (dis)charge voltage at 4.9 V. This high potential is combined with a relatively high maximum charge of 167 mAh ⋅ g − 1 for cycling Li x CoPO 4 between 0 < x < 1, which yields a volumetric capacity of 620 mAh ⋅ cm − 3 for a 289 Å 3 Li 4 Co 4 P 4 O 16 unit cell. When cycling Li x MnPO 4 between 0 < x < 1 around 4.1 V, [ 74 ] a maximum capacity of 171 mAh ⋅ g − 1 can be obtained. With a unit cell of 302.4 Å 3 , [ 75 ] this leads to a maximum theoretic capacity of 590 mAh ⋅ cm − 3 .…”

With the increasing importance of wireless microelectronic devices the need for on-board power supplies is evidently also increasing. Possible candidates for microenergy storage devices are planar all-solid-state Li-ion microbatteries, which are currently under development by several start-up companies. However, to increase the energy density of these microbatteries further and to ensure a high power delivery, three-dimensional (3D) designs are essential. Therefore, several concepts have been proposed for the design of 3D microbatteries and these are reviewed. In addition, an overview is given of the various electrode and electrolyte materials that are suitable for 3D all-solidstate microbatteries. Furthermore, methods are presented to produce fi lms of these materials on a nano-and microscale.www.MaterialsViews.com REVIEW www.advenergymat.de

“…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]. The addition of carbon black resulted in a reduction of particle size while acting as an electrically conductive agent, which is particularly necessary for the operation of LiMnPO4 electrodes given that the inherent electrical conductivity in LiMnPO4 (10 -10 S cm -1 ) is considerably lower than that of LiFePO4 (10 -8 S cm -1 ) [457].…”

Evaluating the performance of nanostructured materials as lithium-ion battery electrodes

Access to the full text of the published version may require a subscription. 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.
