“…This highly reversible mechanism makes it possible to sustain 100% of the specific capacity after 15 cycles. For this compound, the cycling rate does not appear to be a kinetic limitation, as the performances are improved with increasing the cycling rate [53].…”

Rechargeable lithium-ion batteries of today operate by an electrochemical process that involves intercalation reactions that warrants the use of electrode materials having very specific structures and properties. Further, they are limited to the insertion of one Li per 3D metal. One way to circumvent this intrinsic limitation and achieve higher capacities would be the use of electrode materials in which the metal-redox oxidation state could reversibly change by more than one unit. Through the discovery of conversion or displacement reactions, it is possible to reversibly change by more than one unit. Further, the need for materials with open structures or good electronic ionic conductivity is eliminated, thus leading to a new area in materials for lithium ion battery. In this paper, we present a review enlightens new reaction schemes and their potential impact on applications.

“…In most laboratories, ex situ techniques are always undertaken to investigate the failure modes of lithium ion batteries [5][6][7][8][9]. Zhang et al [5] investigated the structure of 0.8LiNiO 2 ·0.2Li 2 TiO 3 cathode materials after being charged to 4.8 V with an extraction capacity of 268 mAh g −1 by ex situ X-ray diffraction (XRD).…”

In this paper, ex situ and in situ devices for Raman observations are designed and compared with each other by using lithium titanate as working electrode. In situ cell is made for Raman spectroscopy based on a confocal microscope Raman spectrometer. The instant evolutions of lithium titanate anode material during cycle can be recorded by in situ Raman in detail. Although the in situ technique is an important method to monitor the structure evolution of lithium titanate, it is difficult to conduct an in situ experiment in most laboratories. Moreover, the existence of electrolyte and surface deposits weakens the Raman signals of sample. Therefore, the structure evolution of Li 4 Ti 5 O 12 cannot be described accurately. For comparison, air-free ex situ device is a simple and cheap tool to achieve the information from lithiated and delithiated samples. By removing the electrolyte and deposits on the sample with dimethyl carbonate, the ex situ Raman pattern shows higher signal to noise ratio than that of in situ Raman result. As a result, the shift and recovery of ex situ Raman bands confirms that the electrochemical reaction of Li 4 Ti 5 O 12 with Li in 0.0-2.0 V is not a fully reversible process but a partially reversible process.

Lithium / Tetrelides / Ionic Mobility / Crystal ChemistryLithium-transition metal (T)-tetrelides (tetr. = C, Si, Ge, Sn, Pb) are an interesting class of materials with greatly differing crystal structures. The transition metal and tetrel atoms build up covalently bonded networks which leave cavities or channels for the lithium atoms. Depending on the bonding of the lithium atoms to the polyanionic network one observes mobility of the lithium atoms. The crystal chemistry, chemical bonding, 7 Li solid state NMR, and the electrochemical behavior of the tetrelides are reviewed herein.
