“…The peak at 3.59 V is related to the initial lithium ion inserted into the octahedral site of the LVO host structure [34]. The peaks at 2.41 and 2.51 V correspond to Li-ion insertion in the empty tetrahedral site with a single-phase reaction, and the peak around 2.34 V may relate to the two-phase transformation of Li 3 [35][36][37][38][39]. While the peak at 3.46 V may stem from the insertion reaction of LiV 2 O 5 [30].…”

“…Third, the sample annealed in nitrogen atmosphere shows higher BET surface area with smaller particles, and it shortens the diffusion pathway for lithium ions so that the composition and the stress gradient are reduced. Lastly, the presence of parasitic secondary phase, LiV 2 O 5 , may serve as a buffer to circumvent the volume change associated with the lithium ion intercalation and deintercalation [39,40]. Although the presence of the secondary phase in LVO cathode material is believed to improve its cyclic life, it is required to have more research to get a better fundamental understanding of the real mechanism.…”

Energy resources, consumption, and management are among the most important issues of this century. Our dependence on fossil fuels should be changed by eco-friendlier renewable energies. Further, the generated electrical energy should be stored for improving mobile applications, being batteries the most used system for this purpose. Lithium-ion batteries are the most promising battery type and are composed of three main elements: cathode, anode and separator/electrolyte. The active material of the cathode is primarily responsible for the battery capacity, and for that reason, different cathode materials have been developed and explored for lithium-ion batteries. In the present work, the most relevant cathode materials are presented, their main properties and characteristics described and their advantage and disadvantage analyzed, allowing understand to which extend those material are suitable for specific applications in this field.

We report on the synthesis of submicron Li1+x V3O8 fibers through a facile mixed ethanol/water solution-mediated solvothermal route in the absence of surfactants. All the raw materials used are commercially available, relatively inexpensive, and low-toxic, and these can be handled in an ambient atmosphere, rendering this synthetic route as reasonably facile and efficient. To ensure a desirable and acceptable sample crystallinity and purity, we introduced a postannealing treatment at 500 °C. The monoclinic phase formation of the fiber sample was probed in detail using a series of X-ray diffraction, scanning electron microscopy, transmission electron microscopy, infrared spectroscopy, X-ray photoelectron spectroscopy, high resolution transmission electron microscopy, and selected area electron diffraction measurements. Both morphology and chemical composition could be carefully and systematically tuned in terms of generating a class of novel, pure, and well-defined motifs of Li1+x V3O8. A plausible mechanism for the formation of submicron-diameter fibers has been discussed in addition to the expected phase transformation within our Li-V-O materials. Our comprehensive study should provide for needed fundamental insights into putting forth a viable synthesis strategy for the generation of well-defined morphological variants of layered oxide materials for battery applications.
