“…Besides, the coating process does not change the element oxidation state by XPS analysis (Figure S3), with the measured values in close proximity to the values reported in previous studies . After modification, the vibration peak of tetrahedron PO 4 can be detected by FTIR and Raman spectra (Figure S4), and these results imply the formation of LATP phase.…”

The rapid capacity decay caused by the poor contact and large polarization at the interface between the cathode and solid electrolytes is still a big challenge to overcome for high-power-density solid batteries. In this study, a superior Li conductive transition layer LiAlTi(PO) is introduced to coat LiNiCoMnO, as a model cathode, to mitigate polarization and enhance dynamic characteristics. The critical attribute for such superior dynamics is investigated by the atomic force microscopy with boundary potential analysis, revealing that the formed interfacial transition layer provides a gradual potential slope and sustain-released polarization, and endows the battery with improved cycling stability (90% after 100 cycles) and excellent rate capability (116 mA h g at 2 C) at room temperature, which enlightens the comprehension of interface engineering in the future solid batteries systems.

“…As illustrated by the FTIR spectra in Figure , OH group, PO 4 3– , HPO 4 2– , and CO 3 2– were detected on the surface of the ACPC composite, such as the stretching vibration peaks at 3570 and 3125 cm –1 . − The OH bending vibration of the ACPC shifted from 1637 cm –1 a little higher to 1 640 for the modified ACPC composite due to incorporation of foreign ions such as Mg and Zn into the lattice. , The OH – vibration peak of HAp in the ACPC at 634 cm –1 became a little stronger because of addition of MgZnCa alloy as well. On the ACPC surface, PO 4 3– was detected according to its antisymmetric stretching and the symmetric stretching peaks at 1033 , and 961 cm – , 1 ,,− respectively, together with its asymmetric deformation bands at 602 and 563 cm –1 . ,, HPO 4 2– was determined at 874 cm –1 as well. The bands at 1400 and 1475 cm –1 were probably due to CO 3 2– replacing PO 4 3– and OH – in the HAp lattice, respectively.…”

Degradability is vital for bone filling and plays an important role in bone regeneration. Evidence indicates that apatite-based calcium phosphate cement (ACPC) is a prospective biomaterial for bone repair with enhanced osteogenesis. However, poor degradability restricts their clinical application. In this study, MgZnCa-doped ACPC (MgZnCa/ACPC) composites were fabricated by adding 3 (wt) % amorphous MgZnCa powder in the solid phase of ACPC to enhance the biodegradation and bioactivity of the apatite ACPC. The chemical and the physical properties of the MgZnCa/ACPC composite were investigated and compared with the ACPC composite. The results showed that the incorporation of MgZnCa improved both the degradability and the compressive strength of the ACPC composite. X-ray diffraction and Fourier transform infrared spectrometry analysis suggested significant changes in the microstructures of the composites due to the incorporation and the anodic dissolution of MgZnCa alloy. These findings indicate that the MgZnCa/ACPC composite is capable of facilitating bone repair and regeneration by endowing favorable degradation property.

“…This phenomenon indicates that these samples obey Vegard's Law [24]. Kahlaoui et al [25] reported that due to the linearity of cell volume-composition relations, the distribution of Li and Ba in Bax/2Li1-xTi2(PO4)3 NASICON-based electrolyte is expected to be random. Thus, Al 3+ and Ti 4+ in Li1+xAlxTixSn2−2x(PO4)3 system are in random distribution.…”

The aim of this study is to synthesize Li1+xAlxTixSn2−2x(PO4) sodium super ion conductor (NASICON) -based ceramic solid electrolyte and to study the effect of dual metal substitution on the electrical and structural properties of the electrolyte. The performance of the electrolyte is analyzed based on the sintering temperature (550 to 950 °C) as well as the composition. The trend of XRD results reveals the presence of impurities in the sample, and from Rietveld Refinement, the purest sample is achieved at a sintering temperature of 950 °C and when x = 0.6. The electrolytes obey Vegard′s Law as the addition of Al3+ and Ti4+ provide linear relation with cell volume, which signifies a random distribution. The different composition has a different optimum sintering temperature at which the highest conductivity is achieved when the sample is sintered at 650 °C and x = 0.4. Field emission scanning electron microscope (FESEM) analysis showed that higher sintering temperature promotes the increment of grain boundaries and size. Based on energy dispersive X-ray spectroscopy (EDX) analysis, x = 0.4 produced the closest atomic percentage ratio to the theoretical value. Electrode polarization is found to be at maximum when x = 0.4, which is determined from dielectric analysis. The electrolytes follow non-Debye behavior as it shows a variety of relaxation times.
