Ascorbic acid acts as both an antioxidant and a surfactant to form organic groups (first carbon source) on the surface of as-solvothermal products, in which the-OH (or H 2 O) groups of glucose (second carbon source) are closely bonded to the surface to form a uniform adsorption layer. Uniform mixed-carbon-coated LiMn 0.4 Fe 0.6 PO 4 nanopowders are formed after calcination, which demonstrate excellent electrochemical performances.

“…[41] are also inclined. Ke Wang et al even observed an additional discharge plateau of Mn 3þ in LiFe 0.5 Mn 0.5 PO 4 at high current rates attributed to presence of Fe in LiMnPO 4 that gives the conditions for better kinetics [44]. In contrast, a flat plateau for the oxidation/reduction of manganese and inclined for oxidation/reduction of iron were observed for LiFe 0.2 Mn 0.8 PO 4 /C [45] and for LiFe 0.15 Mn 0.85 PO 4 /C [42].…”

“…This attempt was successful, in particular when the concentration of Mn does not exceed 0.8 [165]. Indeed, nano-sized carbon-coated LiMn 1−x Fe x PO 4 particles have shown improved properties [166][167][168][169][170][171][172][173][174][175][176][177].…”

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.
