“…The cyclic voltammetry (CV) performance at room temperature of both SP‐15 and STD is depicted in Figure b. Both CV curves replicate the typical redox couple behavior of LiFePO 4 cathodes vs Li/Li + . However, in the case of SP‐15, both oxidation and reduction take place at slightly higher voltages as compared to STD, which might be attributed to the higher inherent impedance of the SP‐15 battery (Figure a).…”

Exploring the benefits of a nanofibrous morphology in electrolyte materials for Li‐battery applications, an approach of fabricating single‐ion conducting electrolyte (SICE) membranes is reported. A nonwoven nanofabric SICE membrane, delivering an outstanding performance, surpassing the conventional liquid electrolyte system at ambient conditions, was fabricated by using an electrospinning technique. When soaked in a carbonate solvent system, the membrane shows high ionic conductivity, electrochemical stability above 5.2 V (vs. Li/Li+) and a lithium transference number (tnormalLnormali+ ) close to unity (0.93). Moreover, a LiFePO4|Li cell assembled with this membrane performs charge/discharge up to the 5 C rate under ambient conditions with a coulombic efficiency close to 100%. The discharge capacities of this battery are found to be higher than those of a battery assembled with a commercial separator/dual‐ion salt electrolyte system up to 2 C, which offers significant progress for SICEs. Unlike most of the earlier reported SICEs that performed like a bulk‐material entity, the innovative approach might be valuable for future developments.

“…Other Fe sources such as Fe 2 O 3 [ 46 ] , Fe 3 (PO 4 ) 2 ·8H 2 O [ 47 ] , NH 4 FePO 4 ∙H 2 O [ 48 ] , β‐FeOOH, FeCl 3 ·6H 2 O [ 49 ] , Fe 3 (PO 4 ) 2 (OH) 2 , organic phase and Fe metal [ 50 ] have been extensively studied and all can be used to produce LiFePO 4 with different morphologies. Generally, when the particles are not seriously stacked, the smaller the size of the LiFePO 4 grains in the [010] direction, the better the electrochemical performance of the electrode materials.…”

The sluggish Li‐ion diffusivity in LiFePO4, a famous cathode material, relies heavily on the employment of a broad spectrum of modifications to accelerate the slow kinetics, including size and orientation control, coating with electron‐conducting layer, aliovalent ion doping, and defect control. These strategies are generally implemented by employing the hydrothermal/solvothermal synthesis, as reflected by the hundreds of publications on hydrothermal/solvothermal synthesis in recent years. However, LiFePO4 is far from the level of controllable preparation, due to the lack of the understanding of the relations between the synthesis condition and the nucleation‐and‐growth of LiFePO4. In this paper, the recent progress in controlled hydrothermal/solvothermal synthesis of LiFePO4 is first summarized, before an insight into the relations between the synthesis condition and the nucleation‐and‐growth of LiFePO4 is obtained. Thereafter, a review over surface decoration, lattice substitution, and defect control is provided. Moreover, new research directions and future trends are also discussed.

“…As an example, Bolloju et al obtained 165 mA g À1 at 0.1C from LiFePO 4 prepared using Fe powder as a precursor, which is comparable to that obtained by conventional chemical synthesis. 155 Fe powder is very advantageous over other precursors because it does not produce harmful anions. Also, there is a 100% atom economy delivered by the iron metal, which makes it cost-effective as well.…”
