“…In a recent review on LiNiPO 4 (LNP) [211], we argued why we are pessimistic on its potential applications for different reasons. One argument was that the discharge voltage at 5.1 V is outside the window of organic liquid electrolytes [243]. Recently, however, Cherkashinin et al reported that LiNiPO 4 films are chemically compatible with LiPF 6 /DMC/FEC/0.2%-TMB electrolyte [244].…”

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.

“…The Fe-Cr-Si-doped LCP cathode materials were synthesized by high-energy ball milling [ 10 ]. The cathode was prepared by mixing LCP, Super P, carbon nanotube and polyvinylidene difluoride (PVDF) with the weight ratio of 90:3.5:1.5:5 in N-methylpyrrolidine (NMP) and coated on aluminum foil.…”

“…Instead of an ethylene carbonate (EC) and ethyl methyl carbonate (EMC)-based electrolyte as described in ref. [ 10 ], we used a room-temperature IL, Py 13 FSI, (Dai-Ichi Kogyo, Seiyaku Co., Ltd., Kagawa, Japan), and 1.2 M LiFSI, (Nippon Shokubai, Osaka, Japan) as the electrolyte. The IL contains less than 10 ppm (w/w) H 2 O and less than 2 ppm (w/w) halide and alkali metal-ion impurities.…”

High-Voltage Lithium-Ion Battery Using Substituted LiCoPO4: Electrochemical and Safety Performance of 1.2 Ah Pouch Cell

A LiCoPO4-based high-voltage lithium-ion battery was fabricated in the format of a 1.2 Ah pouch cell that exhibited a highly stable cycle life at a cut-off voltage of 4.9 V. The high-voltage stability was achieved using a Fe-Cr-Si multi-ion-substituted LiCoPO4 cathode and lithium bis(fluorosulfonyl)imide in 1-methyl-1-propylpyrrolidinium bis(fluorosulfony)imide as the electrolyte. Due to the improved electrochemical stability at high voltage, the cell exhibited a stable capacity retention of 91% after 290 cycles without any gas evolution related to electrolyte decomposition at high voltage. In addition to improved cycling stability, the nominal 5 V LiCoPO4 pouch cell also exhibited excellent safety performance during a nail penetration safety test compared with a state-of-the-art lithium ion battery. Meanwhile, the thermal stabilities of the 1.2 Ah pouch cell as well as the delithiated LiCoPO4 were also studied by accelerating rate calorimetry (ARC), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), and in situ X-ray diffraction (XRD) analyses and reported.

“…Besides, battery life is also seriously affected at low temperature. [5][6][7] The results of Jaguemont et al 8 showed that under severe low-temperature condition, not only the consumption of lithium ion but also the loss of electrode active material and contact area would be aggravated. Li et al 9 proved a considerable loss of active material (LAM) with the increase of current rate when the cycling temperature of ternary battery (NCM/C) was set to −10°C.…”

“…Reasons for this phenomenon are regarded as slow chemical reactions, poor charge‐transfer kinetics, low electrolyte conductivity, and decreased diffusivity of lithium ions within the anode, while Ji et al found that the diffusion of lithium in electrolyte and solid‐state lithium in graphite particles was the principle performance limitation instead of charge‐transfer kinetic or ohmic resistance. Besides, battery life is also seriously affected at low temperature . The results of Jaguemont et al showed that under severe low‐temperature condition, not only the consumption of lithium ion but also the loss of electrode active material and contact area would be aggravated.…”

Summary Limited by the current power battery technology, electric vehicles show extremely poor duration performance and potential risk at low temperature, which is mainly caused by poor charging performance of lithium‐ion batteries. To explore the impact of charging process on cycle degradation at low temperatures, a cycle aging experimental scheme with different charging C‐rate (0.3C and 0.5C) under −10°C and −20°C was designed for the commercial LiFePO4 battery. The experimental batteries showed severe degradation after a few of cycles. The phenomenon of reduced internal resistance and up‐shift of the charging curve was found during the early cycle stages (0th‐20th cycle). The influence of low‐temperature cycle on battery was analyzed by the increment capacity analysis (ICA); the fast decreasing intensity of ①*II showed sharp loss of lithium ions. Those lithium ions mainly transformed into lithium plating and built up dendrites instead of reintercalating into the anode crystal structure, causing the further degradation of capacity and ohmic resistance. Degradation law was obtained by curve regression analysis in the end.
