Synthesis, structures and properties of the new lithium cobalt(II) phosphate Li4Co(PO4)2

α-Li4Co(PO4)2 has been synthesized and crystallized by solid-state reactions. The new phosphate crystallizes in the monoclinic system (P21/a, Z=4, a=8.117(3) A, b=10.303(8) A, c=8.118(8) A, β=104.36(8) A) and is isotypic to α-Li4Zn(PO4)2. The structure of α-Li4Co(PO4)2 has been determined from single-crystal X-ray diffraction data {R1=0.040, wR 2=0.135, 2278 unique reflections with Fo>4σ (Fo)}. The crystal structure, which might be regarded as a superstructure of the wurtzite structure type, is build of layers of regular CoO4, PO4 and Li1O4 tetrahedra. Lithium atoms Li2, Li3 and Li4 are located between these layers. Thermal investigations by in-situ XRPD, DTA/TG and quenching experiments suggest decomposition followed by formation and phase transformation of Li4Co(PO4) 2:α-Li4Co(PO4)2442°C β-Li3PO4LiCoPO4 ?773°C β-Li4Co(PO4)2quenchingto25°C α-Li4Co(PO4)2 According to HT-XRPD at θ=850°C β-Li4Co(PO4)2 (Pnma, Z=2, 10.3341(8) A, b=6.5829(5) A, c=5.0428(3) A) is isostructural to γ-Li3PO4. The powder reflectance spectrum of α-Li4Co(PO4)2 shows the typical absorption bands for the tetrahedral chromophore [CoIIO 4].

Lithium zincopyrophosphate, Li2Zn3(P 2O7)2

The title compound, dilithium(I) trizinc(II) bis-[diphos-phate(4-)], is the first quaternary lithium zincopyro-phosphate in the Li-Zn-P-O system. It features zigzag chains running along c, which are built up from edge-sharing [ZnO5] trigonal bipyramids. O

Phase relations of Li2O-MnO-P2O5 system and the electrochemical properties of Li1+xMn1-xPO4 compounds

The phase relations of Li2O-MnO-P2O5 ternary system under reducing atmosphere have been systematically investigated by means of X-ray diffraction. Inferior to what we expected, no other new lithium manganese phosphates exist within the Li2O-MnO-P2O5 ternary system under the reducing atmosphere. A high-pressure phase Mn3(PO4)2 with graftonite Fe3(PO4)2-type structure can be easily obtained in the MnO-P2O5 system under the ordinary solid-state reaction conditions in H2/Ar atmosphere and its detail structure is presented. In addition, the solid solubility of Li1+xMn1-xPO4 is determined as -0.05 ≤ x ≤ 0.03. The lattice parameters and electrochemical properties of Li1+xMn1-xPO4 with x content are investigated. The electrochemical test results show that excess Li-ion (x > 0) or the excess Mn-ion (x 4 has an unfavorable effect on the electrochemical properties caused by the deterioration of the lithium diffusion along the one-dimensional tunnels.

Effect of Water Vapor on the Formation of Lithium cyclo-Hexaphosphate

The effect of water vapor on the formation of lithium cyclo-hexaphosphate Li6P6O18 (P6m) from trilithium hydrogenpyrophosphate monohydrate Li3HP2O7*H2O was investigated by means of DTA-TG, X-ray diffraction analysis, isothermal heating with electric furnace, and HPLC.Li3HP2O7*H2O lost the water of crystallization at about 180 deg C to give anhydrous Li3HP2O7.At 300 deg C the disproportionation of Li3HP2O7 anhydride to Li4P2O7 and Li4P4O12 (P4m) proceeded faster under humid conditions than under dry air, and subsequently P4m increased with a decrease in P2 and soluble polyphosphates (Ppoly).At 400 deg C, P4m changed largely to P6m under humid conditions.In these reaction processes, water plays an important role as catalyst in the cyclization by dehydration of the end group and in ring opening by attacking the P-O-P bond.At 450 deg C, the amounts of P2 and P6m were almost equal under both humid and dry conditions, because all of P4m thermally changed to P6m.
