Abstract

The emergence of Li‐ion batteries provides a new path and scheme for carbon neutrality and carbon peak. The performance of lithium‐ion batteries is mainly determined by the electrode material. Among them, transition metal compounds have been widely studied in the anode and cathode materials of lithium‐ion batteries. Here, pure rare earth metal fluoride YF3 was synthesized by solvothermal method and subsequent calcination. The specific capacity of YF3 as a Li‐ion battery anode can increase from 29.3 mAh g−1 to 148.5 mAh g−1 after 1000 cycles at 0.1 A g−1, with a growth rate of up to 407 %. XPS and XRD tests confirmed that the lithium storage process was a typical conversion reaction. The successful application of YF3 in Li‐ion batteries provides a wider range for the selection of Li‐ion electrode materials and also provides a new idea for the exploration of new materials for lithium‐ion batteries.

Abstract

Nanocrystal N-Zn-Ag/TiO2 powders were prepared with N-Zn/TiO2 by photo deposition method. A series of pure polymers P3HT[poly(3-hexylthiophene)], P3OT[poly(3-octylthiophene)], P3DT[poly(3-decylthiophene)] and P3DDT[poly(3-dodecylthiophene)], was synthesized, which were used to synthesize p-n type semiconductor materials P3HT/N-Zn-Ag-TiO2, P3OT/N-Zn-Ag-TiO2, P3DT/N-Zn-Ag-TiO2 and P3DDT/N-Zn-Ag-TiO2 by in situ chemical method. X-Ray diffraction(XRD) and infrared(IR) spectroscopy showed the structure of the polymers and complexes. Ultraviolet-visible(UV-Vis) spectra and cyclic voltammograms(CV) showed the optical and electronic performance of the polymers and complexes. Two new single and double organic thin film heterojunction solar cells were prepared with the above mentioned synthesized powders as raw materials. Current-voltage(I–V) measurements indicate that the conversion efficiency of the single organic thin film heterojunction solar cell is higher than that of the double organic thin film heterojunction solar cells. Single organic thin film heterojunction solar cells based on P3DT/N-Zn-Ag-TiO2 can get a photoelectric conversion efficiency of 0.0408%. The performance of electronic transform between electron donor and acceptor on organic thin film solar cells was researched.
