“…Heavy ions are known to induce crystallization in few systems such as ZrC films (Jiang et al, 2021), MAX nanostructures (Cannavò et al, 2021), however, most of the materials exhibit crystalline disorder after irradiation (Sathyavathi et al, 1999;Ai et al, 2019;Pang et al, 2021). Ferrites are known to be stable materials, hence, their crystalline phase remains unchanged under heavy ion irradiation as reported in most of the work.…”

The size-dependent behavior of nanostructured ferrite is well established. Various physical properties such as magnetic, optical and electrical exhibit strong size dependence. Thus, any treatment which causes a change in size is able to modify the characteristics of ferrites. The result of this effect can be seen when these ferrites are subjected to an intense heavy ion beam which modifies the physical properties of ferrites. This modification is related to cation redistribution owing to size change in most of the cases under heavy ion irradiation. However, few recent studies show that cation redistribution may occur under ion irradiation even though no size change is observed. The objective of this review is to highlight this effect in ferrite systems which ultimately may provide ample opportunity for its potential applications.

Lithium dendrites belong to the key challenges of solid‐state battery research. They are unavoidable due to the imperfect nature of surfaces containing defects of a critical size that can be filled by lithium until fracturing the solid electrolyte. The penetration of Li metal occurs along the propagating crack until a short circuit takes place. It is hypothesized that ion implantation can be used to introduce stress states into Li6.4La3Zr1.4Ta0.6O12 which enables an effective deflection and arrest of dendrites. The compositional and microstructural changes associated with the implantation of Ag‐ions are studied via atom probe tomography, electron microscopy, and nano X‐ray diffraction indicating that Ag‐ions can be implanted up to 1 µm deep and amorphization takes place down to 650–700 nm, in good agreement with kinetic Monte Carlo simulations. Based on diffraction results pronounced stress states up to −700 MPa are generated in the near‐surface region. Such a stress zone and the associated microstructural alterations exhibit the ability to not only deflect mechanically introduced cracks but also dendrites, as demonstrated by nano‐indentation and galvanostatic cycling experiments with subsequent electron microscopy observations. These results demonstrate ion implantation as a viable technique to design “dendrite‐free” solid‐state electrolytes for high‐power and energy‐dense solid‐state batteries.

Lithium dendrites belong to the key challenges of solid-state battery research. They are unavoidable due to the imperfect nature of surfaces containing defects of a critical size that can be filled by lithium until fracturing the solid electrolyte. The penetration of Li metal occurs along the propagating crack until a short circuit takes place. We hypothesise that ion implantation can be used to introduce stress states into Li6.4La3Zr1.4Ta0.6O12 which enable an effective deflection and arrest of dendrites. The compositional and microstructural changes are studied via atom probe tomography, FIB-SEM with correlative TOF-SIMS, STEM and nano XRD indicating that Ag-ions can be implanted up to 1 µm deep and amorphization takes place down to 650-700 nm, in good agreement with kinetic Monte Carlo simulations. Based on nano XRD results pronounced stress states up to -700 MPa are generated in the near-surface region. Such a stress zone and the associated microstructural alterations exhibit the ability to not only deflect mechanically introduced cracks but also dendrites, as demonstrated by nano-indentation and galvanostatic cycling experiments with subsequent FIB-SEM observations. These results demonstrate ion implantation as a viable technique to design “dendrite-free” solid-state electrolytes for high-power and energy-dense solid-state batteries.
