“…Mn, Co, Ni are displayed in Fig. 3b [9,[27][28][29][30]. The decrease in capacity of LiFePO 4 upon increasing the doping concentration of cations is due to formation of defect cluster in the system while the cell voltage increased from 3.5 to 4.7 V. Thus the interstitial defect induces electrostatic interactions between the defect regions that lead to agglomerated defect clusters, which restrict the Li + mobility resulting in poor capacity retention [21].…”

The high rate capability and structural stability of the olivine phosphates attracted a lot of interest as promising cathode materials for high energy density batteries. Alteration on these cathode materials, for instance, reducing particle size, conductive coating and metal ion doping were performed in order to improve the conductivity and to obtain high specific Li + diffusion. However, the drastic improvement in electrical conductivity for the aliovalent doping is still unclear. Rather writing a lengthy standard review, this manuscript intends to describe briefly the lattice defects owing to metal ion doping and its influence in improving the cathode performance of the olivine phosphates. This gives a new approach in this field.

“…The olivine compounds LiMPO 4 contain tetrahedral "anion" structure units (PO 4 ) 3-with strong covalent bonding, generating oxygen octahedral occupied by other M metal ions. The PO 4 unit tends to reduce the covalency of the M -O bond, modifying the redox potential for the M 2+ / 3+ couple and thus producing a practical voltage while lithium insertion and re-insertion occurs [7][8]. Among the LiMPO 4 reported in the literature [7][8][9][10], lithium iron phosphate (LiFePO 4; [7]) and lithium manganese phosphate (LiMnPO 4 ; [10]) have been recognised as promising cathode material for rechargeable battery applications.…”

This is mainly because a large reversible capacity of 164 mAh/g was achieved over a wide composition range of Li 1-y Mn y PO 4 and Li 1-y Fe y PO 4 , even at Mn & Fe contents as high as y = 0.75 [11].…”

This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. amorphous NiPO 4 and a minor product of nickel (II) hydroxide (β-NiOOH). During subsequent reduction, lithium ions are not fully intercalated, however, the structure is reversible and adequate for multiple cycles. The high potential in LiNiPO 4 looks to be very attractive in terms of high energy density, given the efficiency is improved.

“…However, its low electronic conductivity [12] and low diffusion coefficient of Li + [13] hinder its commercial applications. At present, various approaches, such as carboncoating [14,15], metal-doping [16][17][18][19][20], and particle-size minimizing [21][22][23][24], have been tried to tackle these problems. So far, a number of literatures [25][26][27][28][29] have been reported that metal-doping (Co 2+ , Cr 3+ , Ti 4+ , V 5+ , Al 3+ , Na + , Ni + , Mg 2+ , Nd 3+ ) can improve the electrochemical performance of LiFePO 4 significantly.…”

Study on LiFe1 − x Sm x PO4/C used as cathode materials for lithium-ion batteries with low Sm component

LiFe 1−x Sm x PO 4 /C cathode materials were synthesized though a facile hydrothermal method. Compared with high-temperature solid-phase sintering, the method can allow for the fabrication of low Sm content (2 %), a scarce and expensive rare earth element, while the presence of an optimized carbon coating with large amount of sp 2 -type carbon sharply increases the material's electrochemical performance. The high-rate dischargeability at 5 C, as well as the exchange current density, can be increased by 21 and 86 %, respectively, which were attributed to the fine size and the large cell parameter a/c as much. It should be pointed out that the a/c value will be increased for the LiFePO 4 Sm-doped papered by both of the two methods, while the mechanism is different: The value c is increased for the front and the value a is decreased for the latter, respectively.
