“…It was found that the plastic deformation of the precursor is effective in the second stage of Li 3 V 2 (PO 4 ) 3 synthesis. XRD patterns of samples subjected to mechanical activation and annealing at 600°C for 7h featured peaks due to Li 3 V 2 (PO 4 ) 3 and LiVP 2 O 7 phases, as shown in Fig. 6.…”

“…We identified four peaks of Li 3 V 2 (PO 4 ) 3 and LiVP 2 O 7 peaks in XRD patterns of the initial VPO 4 -Li 2 CO 3 mixture annealed at 700°C for 10h. By applying dual phase Rietveld refinement to our XRD data [8], we established that the phase ratio Li 3 V 2 (PO 4 ) 3 :LiVP 2 O 7 was 8:2 for the init ial mixture and 9:1 fo r the mixture annealed at 800°C for 6h.…”

“…In addition to small and large energy, a significant need for highly efficient generators of electricity and batteries demand on transport, portable (mobile phones, gadgets, laptops, etc.) technology, aviation, space and other fields [1][2][3]. Fo r the autonomous wind and solar power sources it is appropriate to use electrochemical batteries.…”

Original method for synthesis of lithium vanadium phosphate was developed. The method includes two stages: 1st, synthesis of iron phosphate from a mixture of ammonium dihydrophosphate and metal oxide; and 2st, synthesis of lithium vanadium phosphate by thermal lithiation of the product obtained in the 1st stage, with mechanical activation of the precursor in the course of plastic deformation. Our results would provide some basis for further improvement on the Li3V2(PO4)3 electrode materials for advance lithium-ion batteries.

“…3 Accordingly, nonfluorine polymers like sulfonated polyether ether ketone (SPEEK) are of significant interest due to their low costs and outstanding electrochemical properties. 8,9 CeO 2 is a good radical scavenger which mitigates membrane degradation during water electrolysis. Recently, tungstophosphoric acid (TPA) or molybdophosphoric acid (MoPA) and CeO 2 included SPEEK composite membranes have been reported by this lab.…”

“…11 FT-IR spectra for the identification of three CL-SPEEK composite including TSiA (composite/TSiA), Cs substituted TSiA (composite/Cs-TSiA), and Cs substituted TSiA and CeO 2 (composite/Cs-TSiA/CeO 2 ) were shown in Figure 2. 8,15 Proton conductivities of CL-SPEEK/Cs-TSiA/CeO 2 membranes including Cs-TSiA and CeO 2 , composite/Cs-TSiA/ CeO 2 (1, 2, 3, 4%) in Table 1 decreased as CeO 2 ratio increased. The strong interaction of sulfonic acid group in the ionomer with TSiA results in band shifts to lower wave numbers.…”
