“…The same overall oxygen transport features can not be expected to occur in the case of a MgO x layer, due to its Mg 2+ ionic conductivity [40], but the non-volatile and irreversible oxidation of the Co surface under forward bias may still be understood. While we expect the reaction in Eq.…”

The perpendicular magnetic anisotropy at the Co/oxide interface in Pt/Co/MOx (MOx = MgOx, AlOx, TbOx) was modified by an electric field using a 10 nm-thick ZrO2 as a solid electrolyte. The large voltage-driven modification of interfacial magnetic anisotropy and the non-volatility of the effect is explained in terms of the migration of oxygen ions towards/away from the Co/MOx interface. While the effect is reversible in Pt/Co/AlOx and Pt/Co/TbOx, where the Co layer can be oxidised or reduced, in Pt/Co/MgOx the effect has been found to be irreversible. We propose that these differences may be related to the different nature of the ionic conduction within the MOx layers.

“…The ionic transport properties of MgO and Al 2 O 3 are, instead, fully defined, since nanosized MgO exhibits Mg 2+ ionic conductivity [40] and Al 2 O 3 exhibits ionic conductivity due to oxygen ions [41], though we could not exclude a small contribution of electronic conductivity for the non-stoichiometric oxides.…”

In the last few decades, there has been a trend involving the use of nanoscale fillers in a variety of applications. Significant improvements have been achieved in the areas of their preparation and further applications (e.g., in industry, agriculture, and medicine). One of these promising materials is magnesium oxide (MgO), the unique properties of which make it a suitable candidate for use in a wide range of applications. Generally, MgO is a white, hygroscopic solid mineral, and its lattice consists of Mg2+ ions and O2− ions. Nanostructured MgO can be prepared through different chemical (bottom-up approach) or physical (top-down approach) routes. The required resultant properties (e.g., bandgap, crystallite size, and shape) can be achieved depending on the reaction conditions, basic starting materials, or their concentrations. In addition to its unique material properties, MgO is also potentially of interest due to its nontoxicity and environmental friendliness, which allow it to be widely used in medicine and biotechnological applications.

“…The main improvement methods are adding nano-fillers, compounding with plasticizers, and so on ( Figure S1E) (Cheng et al, 2018). Specific examples of nano-fillers include ZnO, MgO, Al 2 O 3 , polyethylene, and polystyrene (Kim, 2017;Wu N. et al, 2017;Tripathi and Kumar, 2018).…”

Methods to Improve Lithium Metal Anode for Li-S Batteries

et al. 2019

The lithium-sulfur (Li-S) battery has received a lot of attention because it is characterized by high theoretical energy density (2,600 Wh/kg) and low cost. Though many works on the "shuttle effect" of polysulfide have been investigated, lithium metal anode is a more challenging problem, which leads to a short life, low coulombic efficiency, and safety issues related to dendrites. As a result, the amelioration of lithium metal anode is an important means to improve the performance of lithium sulfur battery. In this paper, improvement methods on lithium metal anode for lithium sulfur batteries, including adding electrolyte additives, using solid, and/or gel polymer electrolyte, modifying separators, applying a protective coating, and providing host materials for lithium deposition, are mainly reviewed. In addition, some challenging problems, and further promising directions are also pointed out for future research and development of lithium metal for Li-S batteries.
