“…At fully discharged state, the XPS C 1s sp3 to C─N peak area ratio remains similar to the pristine state at 0.87 (Fig. 3C) (55,56). The quasi-solid-state electrolyte restricts proton storage in CuHCF, which is consistent with the electrochemical data.…”

Mg-ion batteries offer a safe, low-cost, and high–energy density alternative to current Li-ion batteries. However, nonaqueous Mg-ion batteries struggle with poor ionic conductivity, while aqueous batteries face a narrow electrochemical window. Our group previously developed a water-in-salt battery with an operating voltage above 2 V yet still lower than its nonaqueous counterpart because of the dominance of proton over Mg-ion insertion in the cathode. We designed a quasi-solid-state magnesium-ion battery (QSMB) that confines the hydrogen bond network for true multivalent metal ion storage. The QSMB demonstrates an energy density of 264 W·hour kg −1 , nearly five times higher than aqueous Mg-ion batteries and a voltage plateau (2.6 to 2.0 V), outperforming other Mg-ion batteries. In addition, it retains 90% of its capacity after 900 cycles at subzero temperatures (−22°C). The QSMB leverages the advantages of aqueous and nonaqueous systems, offering an innovative approach to designing high-performing Mg-ion batteries and other multivalent metal ion batteries.

“…Additionally, the peak at 941 cm −1 can be ascribed to the stretching vibration of the Sn-O bond, which originated from the SnO 2 formed on the Fe 3 O 4 surface. In the case of the APTES-treated Fe 3 O 4 -SnO 2 nanoparticles, an absorption peak was observed at approximately 3300 cm −1 , corresponding to the symmetric and asymmetric stretching modes of NH/NH 2 [27,28]. The peak at 1048 cm −1 can be ascribed to the Si-O-Si bond, which originated from the silane group of APTES [27].…”

Multilayered core–shell Fe3O4-SnO2-C nanoparticles were prepared via surface treatment and carbonization at atmospheric pressure. Fe3O4-SnO2 nanoparticles were prepared by the carboxylation of the pivotal particles (Fe3O4) with an anionic surfactant to immobilize SnO2 nanoparticles. A method was proposed to externally surround hydrophilic carbon with amine-forming materials, polyethyleneimine (PEI), and (3-Aminopropyl) triethoxysilane (APTES). The synthesis strategy was based on the electrostatic bonding of the introduced amine group with the hydroxyl group on the carbon precursor and the carbonization of the coating layer by the catalytic reaction of sulfuric acid.

“…The N was detected in trace amount on the surface of reference, GA, and JET samples (Table 2), while after treatment by DCSBD, the nitrogen concentration slightly increased similarly as documented in related works. [22][23][24] To elucidate the nature of the changes in the chemical bonding on the surface after treatment, we thoroughly analysed the C 1s and Si 2p region of XPS spectra presented in Fig. 3.…”
