“…2−5 Mixed aluminum, titanium, and lithium phosphates in various stoichiometries, such as Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 , are promising as solid electrolytes for lithium ion batteries because of their high ionic conductivities. 6 Titanium and aluminum phosphate thin films or mixtures of these with other phosphates may prove to be beneficial also for some other applications. As an example, amorphous phosphates of TiP 2 O 7 and Ce 1−x Ti x P 2 O 7 are promising candidates for advanced sunscreen materials in UV-shielding plastics and film applications.…”

The atomic layer deposition (ALD) of phosphate containing thin films using reactions between the metal halide and the phosphorus source without any additional oxygen sources was examined. Two very common metal halides, AlCl 3 and TiCl 4 , were used in conjunction with trimethyl phosphate (TMPO) to grow corresponding metal phosphate films. Aluminum phosphate thin films were deposited at temperatures between 150 and 400 °C while titanium phosphate films grew between 275 and 450 °C. Amorphous films of Al 2.6 PO 7.0 and Al 1.6 PO 5.6 were deposited at 200 and 300 °C, respectively, while the amorphous titanium phosphate films deposited at 300 and 400 °C consisted of Ti 0.8 PO 3.9 and Ti 0.6 PO 3.5 (Ti 1.2 P 2 O 7 ). The stability and crystallization of the films were studied with high temperature XRD, while the surface morphology of the annealed films was studied using FESEM.

All solid lithium-ion batteries (ASLB) have gained a lot of attention as it could deliver high energy and power density. In order to completely establish ASLB, proper understanding of solid electrolyte is very vital and the research from diverse point is still undergoing. Among them, NASICON-type phosphate based solid electrolytes are one of the promising materials due to good ionic conductivity and atmospheric stability. Addition of proper dopants into the parent material could cause an increment in their ionic conductivity as well as stability, thus fitting the material apt as solid electrolyte. This study aims in understanding the effect of ionic conductivity and stability of Lithium Aluminium Germanium Phosphate (LAGP) material upon adding Zinc as dopant material. We explored the effect of structural, ionic conductivity, stability against Li and Ac conductivity properties of Li1.5Al0.5−xZnxGe1.5(PO4)3 solid electrolyte with x = 0, 0.1 and 0.2. Our study showed that doping of aluminium with slightly bigger Zn ion could enhance the stability and conductivity of the material without changing the crystal structure. When x = 0.1 the ionic conductivity of the material attained is 1 × 10−5 S cm−1 at RT, which reaches 2.57 × 10−5 S cm−1 at 60 °C. Such a change in conductivity arises due to the expansion of ionic pathways which can be further tuned by exploring the limiting concentration 0 ≤ x < 0.1. Moreover, the sample also showed good stability at 0.03 and 0.05 mA cm−2 current densities against Li metal. Present study shows that Zn doping can improve the ionic conductivity of LAGP moderately and it can be used as a solid electrolyte for fabricating all-solid-state batteries.
