Crystal structure analysis of Li3PO4 powder prepared by wet chemical reaction and solid-state reaction by using X-ray diffraction (XRD)

Room temperature synthesis and phase transformation of lithium phosphate Li3PO4as solid electrolyte

“…These values were in good agreement with the previous results, e.g. a = 6.1295(2) Å, b = 5.2546(2) Å, and c = 4.8705(1) Å [14]. Chemical composition of the Li 3 PO 4 sample was analyzed by ICP-OES.…”

“…This may be affected by the different synthetic procedures of β-Li 3 PO 4 at low temperatures, however, unfortunately, chemical information for these samples could not be reported in the literatures [12,13]. Recently, Ayu et al re-investigated the crystal structure of β-Li 3 PO 4 using the sample prepared by reaction of LiOH and H 3 PO 4 at 40°C [14]. However, they have never revealed the structure transformation from β-to γ-Li 3 PO 4 using the as-prepared β-Li 3 PO 4 sample.…”

Binding Li3PO4 to Spinel LiNi0.5Mn1.5O4 via a Surface Co‐Containing Bridging Layer to Improve the Electrochemical Performance

“…The enlarged region in the 2 θ range of 22–35° (Figure 1b) shows the presence of β‐Li 3 PO 4 for the coated and reference samples. [ 15 ] The indexing of the β‐Li 3 PO 4 pattern is shown in Figure S1, Supporting Information. The lattice parameter a is calculated using the Rietveld refinement method, and the parameters are nearly the same for the bare LiNi 0.5 Mn 1.5 O 4 sample, ≈8.1721(1) Å, the coated LiNi 0.5 Mn 1.5 O 4 sample, ≈8.1720(3) Å, and the reference sample, ≈8.1724(1) Å, without showing any significant changes from that of bulk LiNi 0.5 Mn 1.5 O 4 after the hydrothermal process.…”

“…It is difficult to uniformly coat Li 3 PO 4 on the surface of cathodes due to structural incompatibility and the inactive interface between Li 3 PO 4 and cathodes. [ 2,15 ] We designed a method with the help of intermediate metal ions that can easily diffuse into the structure of the coated cathodes. The metal ions were Co ions, and the cathode was spinel LiNi 0.5 Mn 1.5 O 4 .…”

Flow-driven crystal growth of lithium phosphate in microchannels

“…7, we have identified that the crystals are the orthorhombic, low form of lithium phosphate. 43 The X-ray diffraction data also indicate that the lithium phosphates obtained from both the microchannel and the well-stirred reference system belong to the same space group of Pmn2 1 (orthorhombic) 43 which corresponds to β-Li 3 PO 4 prepared mostly from a wet chemical reaction, 44 with corner-sharing tetrahedra pointing towards the same direction along the main c axis. 45,46 The crystallinity of the samples is ∼67% from both the reference and the microfluidic system within the experimental error.…”
