“…Significant effort has been made in searching for potential substitutes for graphite as the anode material. Generally speaking, metal oxides have poor electrical conductivity, but this can be improved by doping with other elements [15,16]. Therefore the manganese-based ternary oxides may have better performance in LIBs compared with manganese 3 oxides.…”

Transition metal oxides are attractive as anode materials in lithium-ion batteries for their high theoretical capacity and good performance. In this work, an anode material based on manganese-based oxide FeMnO 3 in LIBs is investigated for the first time. FeMnO 3 is prepared with graphene and the FeMnO 3 /graphene composite exhibits a high discharge capacity of 1155.3 mAh g-1 after 300 cycles at 200 mA g-1 , as well as a superior rate performance of 851.7 mAh g-1 at a current density of 3200 mA g-1. The observed extraordinary performance is believed to be attributed to the combination of the intrinsically high capacity of FeMnO 3 , a large surface area of 89.65 m 2 g-1 and good electrical conductivity of the FeMnO 3 /graphene composite. To help clarify the properties of this new material, we employ first principles calculations to determine the structural stability, electronic structure, and Li

“…In fact, NiO films have been widely studied as a promising p-type transparent conducting oxides (TCOs) [48][49][50][51][52]. One of the most attractive advantages of NiO is the possibility of modifying its electrical conductivity.…”

“…One of the most attractive advantages of NiO is the possibility of modifying its electrical conductivity. Doping of some monovalent atoms such as lithium [53][54][55][56], sodium [57], and potassium [52] can increase the number of Ni 3 þ ions and then increase the electrical conductivity of NiO films. Among them, the ionic radius of Li þ is 0.76 Å, which is similar to the ionic radius of Ni 2 þ (0.69 Å).…”

“…It is well known that the electrical properties can be adjusted by doping appropriate dopants into the NiO crystal lattice. Most of the researches focused on single‐element doping for NiO films, such as K, Cu, Na, and Li, but there are limited studies on the effect of several elements co‐doping on the electrical properties of NiO thin films. The single‐element doping usually optimized only the electrical properties of NiO but deteriorated its optical properties.…”

Cu–K co‐doped NiO films (Ni1–2xCuxKxO and x = 0–0.05) are deposited on common glass substrates by the spin‐coating sol–gel method. The phase and the morphological, optical, and electrical properties of NiO films as a function of the Cu–K co‐doping concentration are explored by X‐ray diffraction, scanning electron microscopy, and ultraviolet–visible spectrophotometer and Hall effect measurement systems, respectively. All the films are pure phases of the cubic rock‐salt structure. As the doping concentration increases, the preferred orientation of the Ni1–2xCuxKxO films changes from (200) to (111). Moreover, the surface morphologies of the films are obviously affected by the Cu–K co‐doping concentration. The absorption coefficients of the Cu–K co‐doped NiO films are relatively higher than that of the undoped film on the whole in the visible region except x = 0.02. With the increase in doping concentration, the resistivity of the films decreases on the whole. Finally, the figures of merit (FOM) of the films are considered, and the maximum FOM of the films is achieved at x = 0.02.
