A hexagonal prism CuSn alloy was prepared at room temperature from 1-ethyl-3-methylimidazolium dicyanamide ([Emim][DCA]) by the direct template-free electrodeposition method with different concentrations of Cu(I) and Sn(II) at a low current density of 0.04 A dm−2. Moreover, the electrodeposition time was also investigated, and the results indicated that the composition of the CuSn alloy became complex and the structure turned unstable with expanding time. The cycling performance of the hexagonal prism-structural CuSn electrode was investigated, with the first discharge capacity of 345 mAh g−1 and a discharge capacity of about 210 mAh g−1 after 10 cycles.

A novel vanadium pentoxide (V2O5) nanoplatelet has been prepared by an oxalic acid assisted sol–gel method using β-cyclodextrin as an exfoliation agent followed by sintering at a high temperature. Crystal structure and morphology are analyzed using X-ray diffraction (XRD) and scanning electron microscopy (SEM), respectively. Due to about 10 nm thick, the product shows a large chemical diffusion coefficient of Li+ ions over 10-10 cm2 s-1 at room temperature. In the potential range of 4.0–2.0 V (vs. Li/Li+ ), it can deliver an initial capacity of 291 mAh g-1 at 0.1 C rate, which equals approximately to the theoretic one. It also shows excellent rate ability and good cycling performance at room temperature. The primary results suggest this two-dimensional nanomaterial could be developed into a promising cathode material for lithium-ion batteries.

Li2ZrO3-coated and Al-doped micro-sized monocrystalline LiMn2O4 powder is synthesized through solid-state reaction, and the electrochemical performance is investigated as cathode materials for lithium-ion batteries. It is found that Li2ZrO3-coated LiAl0.06Mn1.94O4 delivers a discharge capacity of 110.90 mAhg−1 with 94% capacity retention after 200 cycles at room temperature and a discharge capacity of 104.4 mAhg−1 with a capacity retention of 87.8% after 100 cycles at 55 °C. Moreover, Li2ZrO3-coated LiAl0.06Mn1.94O4 could retain 87.5% of its initial capacity at 5C rate. This superior cycling and rate performance can be greatly contributed to the synergistic effect of Al-doping and Li2ZrO3-coating.

The purpose of this research is to develop tin oxide electrode for lithium ion polymer battery. We have investigated cyclic voltammetry and charge/discharge cycling of SnO2/SPE/Li cells. The first discharge capacity of SnO2 anode was 612mAh/g. The discharge capacity of SnO2 anode was 560 and 376mAh/g at 2nd and 15th cycle at room temperature, respectively. The SnO2 composite anode with PVDF-PC-EC-LiClO4 electrolyte showed good cycling performance.

Efficient Recovery

The consumption of lithium has increased dramatically in recent years. This can be primarily attributed to its use in lithium-ion batteries for the operation of hybrid and electric vehicles. Due to its specific properties, lithium will also continue to be an indispensable key component for rechargeable batteries in the next decades. An average lithium-ion battery contains 5–7% of lithium. These values indicate that used rechargeable batteries are a high-quality raw material for lithium recovery. Currently, the feasibility and reasonability of the hydrometallurgical recycling of lithium from spent lithium-ion batteries is still a field of research. This work is intended to compare the classic method of the precipitation of lithium from synthetic and real pregnant leaching liquors gained from spent lithium-ion batteries with sodium carbonate (state of the art) with alternative precipitation agents such as sodium phosphate and potassium phosphate. Furthermore, the correlation of the obtained product to the used type of phosphate is comprised. In addition, the influence of the process temperature (room temperature to boiling point), as well as the stoichiometric factor of the precipitant, is investigated in order to finally enable a statement about an efficient process, its parameter and the main dependencies.
