“…The energy dispersive spectroscopy (EDS) mapping of an eggshell particle shows the distribution of Ag, Zn, In, and Ga, where In was located in the center of the sphere and Zn, Ga, and Ag were located mainly at the shell (Figures 1h and S4). In the high-resolution X-ray photoelectron spectroscopy (XPS) (Figure S5), Ga 3+ , In 0 , Ag 0 , and Zn 2+ species were identified, 11,27 consistent with the composition. Various EGaIn-based materials, including EGaIn (Figure S1), EGaIn/Ag (Figure S2), EGaIn/ZnO (Figure S6), and EGaIn/Ag/ZnO, were fabricated into pressure sensors.…”

“…6, after Cr element added, the main shape of the composite material was cube shape, in addition, carpet-like flake particles were also found. In previous research, 16 we found that the material of manganese carbonate is easy to form a cube structure. The doping of Cr element makes the material form a carpet-like sheets.…”

Manganese-based compounds have very stable electrochemical properties when applied to aqueous zinc-ion battery. However, it is easy to dissolve manganese in the process of charge and discharge, leading to the collapse of the cathode material structure. In our study, the composite materials of manganese carbonate and magnesium carbonate were synthesized by hydrothermal method, and its properties were optimized by doping modification. According to the electrochemical test, the electrochemical performance of the material synthesized by doping 5% Cr element is relatively stable, the capacity rises to 212.01 mAh/g. Scanning electron microscopy showed that in addition to the cube shape, there are also carpet-like sheets made of nano-sized petal-like structures joined together, which greatly increases the specific surface area of the material. Energy-dispersive spectroscopy and X-ray photoelectron spectroscopy tests confirmed that the types and valence states of elements in the composites were consistent with those in manganese carbonate and magnesium carbonate. It can also be seen from the infrared and Raman tests that the functional groups in the synthesized material correspond to the molecular formula. No obvious impurity peaks are seen in the X-ray diffraction pattern, indicating that the material is mainly composed of manganese carbonate and magnesium carbonate.

“…Therefore, constructing composite materials is an effective solution, since it can improve the conductivity of cathode materials and inhibit the dissolution of cathode materials. In previous research, 12 composite materials of zinc oxide and manganese carbonate were synthesized by hydrothermal method, and it was found that the electrochemical performance of aqueous zinc ion battery materials could be well improved by composite materials and doping modification. Therefore, in the work of this paper, the Mg 1−x Y x CO 3 @2MnCO 3 composite material is prepared.…”

The capacity attenuation of manganese-based materials during the charge-discharge cycle seriously affects the improvement of electrochemical performance. To solve the problem of capacity attenuation, magnesium carbonate material was combined with manganese carbonate material, and the magnesium site was doped and modified. The Mg0.98Zn0.02CO3@2MnCO3 material with the most stable electrochemical properties was optimized, the capacity is up to 283.65mAh/g under the current density of 100mA/g. Subsequently, the characterization test was carried out to further confirm the composition of the material. It can be observed from scanning electron micoroscopy that the material has two main structures: cube shape and spheroid shape, and nanowires grow on the cube structure. energy-dispersive spectroscopy and X-ray photoelectron spectroscopy tests were carried out on the Mg0.98Zn0.02CO3@2MnCO3 material and the results showed that the elements contained in Mg0.98Zn0.02CO3@2MnCO3 material were consistent with the valence states of the elements in manganese carbonate and magnesium carbonate. Through infrared and Raman tests on the material, the data showed that the functional groups in the material were also consistent with the molecular formula. X-ray diffraction testing showed no obvious impurity peak, which proved that the electrochemical performance of Mg0.98Zn0.02CO3@2MnCO3 composite material synthesized by hydrothermal method is relatively stable.
