“…The results of the crystal structure calculation are similar to those reported in other relevant literatures. [ 8,9,23,49 ] In the work of Lin et al, the volume changes of the doping of Mn in LiCo 1− x Mn x PO 4 and CoMnPO 4 with x = 0.5 are ~1.7% and ~9.4% (with x = 0.25 are ~1.7% and 2.0%). [ 50 ] Therefore, in this work, the criterion for volume change before and after doping was chosen as a relatively conservative value (less than 5.0%), and the screening results according to this screening criterion are shown in Figure 2B, marked as “√”.…”

“…In 2017, Karthikprabhu et al successfully prepared the Mn 2+ ‐doped LiNiPO 4 through a polyol strategy and investigated its corresponding battery characteristics. [ 23 ] The doping of Mn 2+ improves the electronic and ionic conductivity of LiNiPO 4 , but the corresponding capacity is only 94.2 mAh·g −1 and the capacity retention rate is only 60% after 100 cycles. In 2019, Karthickprabhu et al synthesized the bare and Nd 3+ ‐doped LiNiPO 4 by polyol process assisted by 1,2‐proanediol.…”

LiNiPO4 (working at ~5.1 V) shows potential advantages in the competition of cathode materials for lithium‐ion batteries (LIBs) because of high energy density. However, the high‐voltage electrolyte developed can only remain relatively stable in the range of less than 4.8 V, so the operating voltage of LiNiPO4 needs to be adjusted to smaller to better exploit its high‐voltage advantages. To regulate the operating voltage of LiNiPO4 while ensuring the relative stability of its electrochemical properties, in this work, all the 3d, 4d, and 5d transition metals (TMs) are, respectively, doped into the Ni site of LiNiPO4 to screen out the doped models with excellent electrochemical performance. In particular, the changes in lattice structure, electronic properties, formation energy, mechanical properties, anisotropy, and working voltage were used as screening criteria. By considering the above screening criteria, the Cr‐ and Fe‐doped LiNiPO4 with open circuit voltage ~4.7 and ~4.8 V are considered to have leading performance and can be used for applicable high‐voltage LIBs. The screening results of this work can provide an overall understanding of the doping of LiNiPO4 by TMs and have advanced a theoretical idea for the design of new high‐voltage LIBs cathode materials.

“…The partial substitution of Co for Ni increases the capacity but even in most recent works, the capacity retention remains very small [246]. Better results were obtained with LiNi1−xMnxPO4 (x = 0.05-0.2) cathode materials prepared by a facile polyol method [247]. In particular, for x = 0.1, the initial discharge capacity was 94 mAh g −1 at C/4 rate, and 62% capacity retention after 100 cycles between 2.8 and 5.6 V.…”

Among the compounds of the olivine family, LiMPO 4 with M = Fe, Mn, Ni, or Co, only LiFePO 4 is currently used as the active element of positive electrodes in lithium-ion batteries. However, intensive research devoted to other elements of the family has recently been successful in significantly improving their electrochemical performance, so that some of them are now promising for application in the battery industry and outperform LiFePO 4 in terms of energy density, a key parameter for use in electric vehicles in particular. The purpose of this review is to acknowledge the current state of the art and the progress that has been made recently on all the elements of the family and their solid solutions. We also discuss the results from the perspective of their potential application in the industry of Li-ion batteries.The main disadvantage of olivines with respect to other cathode chemistries for lithium batteries is the lower energy density. This is evidenced in Table 1 where we have reported the gravimetric and volumetric energy densities of LFP and two other cathode materials which have also found a market place in commercial batteries for electric vehicles: the manganese spinel LiMn 2 O 4 , and "LiNiCoAl" (NCA). In terms of energy density, the winner is clearly NCA, the cathode material used by Panasonic to manufacture the batteries of Tesla cars. However, the low energy density of LFP was not an obstacle for its success for EV applications. The top-selling EV manufacturer in the world today is BYD, which makes its own batteries. Its success comes from its choice of the LFP cathode chemistry. As an example, BYD's LFP battery used by e6 taxis in Shenzen has a driving range of 200 km and can be charged to 80% in just 20 min, or 100% in only 40 min using a BYD DC fast charger. The town has 12,000 taxis which will be electric by the end of this year, and all of the 7,000,000 buses are already electric buses, 80% being BYD buses.

Butyric anhydride (BA) is used as an effective functional additive to improve the electrochemical performance of a high‐voltage LiNi0.5Mn1.5O4 (LNMO) cathode. In the presence of 0.5 wt % BA, the capacity retention of a LNMO/Li cell is significantly improved from 15.3 to 88.4 % after 200 cycles at 1 C. Furthermore, the rate performance of the LNMO/Li cell is also effectively enhanced, and the capacity goes up to 112 mAh g−1 even at 5 C, which is considerably higher than that of a LNMO/Li cell in electrolyte without BA additive (95.4 mAh g−1 at 5 C). Linear sweep voltammetry and cyclic voltammetry results reveal that the BA additive can be preferentially oxidized to construct a stable cathode electrolyte interphase (CEI) film on the LNMO cathode. Subsequently, the BA‐derived CEI film can alleviate the decomposition of the electrolyte and the dissolution of Mn and Ni ions from the LNMO cathode as well as maintain the structural stability of LNMO during the cycling process; this leads to outstanding electrochemical performance. Thus, this work provides an effective and low‐cost functional electrolyte for high‐voltage LNMO‐based LIBs.
