“…Lithium iron phosphate LiFePO 4 (LFP) has been selected as one of the positive electrode material of batteries for electric vehicles (EVs) and hybrid electric vehicles (HEVs), and more generally for high-power applications, owing to its thermal and structural stability in the fully charged state, its little hygroscopicity and its exceptional high-rate performance [1]. This material exhibits a relatively large specific capacity even at high C-rate (close to the theoretical value of 170 mAhg -1 ) compared with other iron-based compounds.…”

“…Therefore, a good idea was proposed to use the solid solution LiMnxFe1-xPO4, with its intermediate composition to be the best compromise, and take advantage of the Mn 2+ /Mn 3+ redox potential without losing too much in the cycling life and power [22]. Recently coating LiMnPO4 with a thin layer of LiFePO4 was proposed to take benefit of the catalytic reaction of Fe with C, which could open a new route to improve the performance of the olivine family as the cathode materials for LIBs [23]. The composite has been proven to show a better electrochemical performance [23].…”

Abstract:Coating LiMnPO4 with a thin layer of LiFePO4 shows a better electrochemical performance than the pure LiFePO4 and LiMnPO4, thus it is critical to understand Li diffusion at their interfaces to improve the performance of electrode materials. Li diffusion at the (100)LiFePO4//(100)LiMnPO4, (100) interface is in the range of 3.65×10 -11 -5.28×10 -12 cm 2 /s, which is larger than that in the pure LiMnPO4 with a value of 7.5×10 -14 cm 2 /s. Therefore, the charging/discharging rate performance of the LiMnPO4 can be improved by surface coating with the LiFePO4.

The goal of this critical review is to explain why the safety problem raised by the lithium batteries must be considered. The performance of the batteries with different chemistries is compared and analyzed, with emphasis on the safety aspects, in addition to the electrochemical properties of the cells. Problems encountered with cathode materials (layered compounds, spinel and olivine), anode materials (graphite and lithium titanate), electrolytes, lithium salts, and separators are pointed out. In this critical review, we also discuss the place of the lithium batteries in the context of sustainable energies (electric vehicles, smart grid).
