The electrification of the transportation sector exacerbates all issues concerning the use of critical materials in state‐of‐the‐art batteries and, therefore, urges the development of new technologies based on potentially greener and more abundant materials. One research trend is the substitution of Li as shuttle ion with other elements such as Na, K, Mg, Ca, Zn, Al, that is, the so‐called post‐Li technology. Although significant progress has been achieved in this field recently, these novel battery chemistries are mostly not matured yet. In the present work, the development of new battery materials by screening the materials’ class of oxide perovskites as high‐energy insertion‐type cathode material is addressed. Based on density functional theory calculations, the specific energy, the energy density, the volume change, and the energy above hull are derived for 280 compounds and appropriate screening criteria are employed. In a second step, the diffusion barriers are determined for the most suitable materials. Eventually, , ZnVO, and are suggested as candidate materials for post‐Li batteries for further investigation with appearing particularly promising.

Using a microscopic model and Green’s function theory, we have calculated the band gap energy and the polarization of LiNbO3, KNbO3, AgNbO3, and NaNbO3. The effects by substitution of different ions at A or/and B sites for doping concentration x = 0–0.1 are studied. The observed different tuning of these properties is discussed for the possibility of photovoltaic and energy storage applications of these compounds. They should have a large polarization and narrow band gap. It is shown that the band gap of all substances decreases or increases with increasing Fe or Zn dopant at the Nb site, respectively. But the substitution, for example, of Ba at the A site, leads to different behaviors of these materials. The polarization increases by Ba doping at the A site and decreases by Fe doping at the Nb site. For example, by Ba/Fe, Ba/Ni co-doping (Ba at the A site and Fe, Ni at the B site) we observe both an enhanced polarization and reduced band gap.

In this work, we used femtosecond‐laser direct writing to fabricate two kinds of modified structures with opposite refractive‐index changes to build fork‐grating configurations in z‐cut LiNbO3 (LN) crystals. Experimental and simulation results indicate that the fork grating combined with the modified area of the refractive index increased and refractive index decreased produces a more effective diffraction effect at 532 nm. The diffraction results of these fork gratings have been investigated. Compared with the fork grating only with the refractive‐index‐decreased filaments, when the incident beam is at transverse magnetic, transverse electric, and circular polarizations, the diffraction efficiency is improved by 5.3%, 4.3%, and 9.6%, respectively. Our work provides a new perspective for improving the diffraction efficiency of fork gratings in LN crystals.
