Nanoboxes with a porous MnO core and amorphous TiO₂ shell as a mediator for lithium–sulfur batteries

Abstract

Nanoboxes with a porous MnO core and amorphous TiO2 shell have been synthesized via a wet-chemistry method for the first time.

Synthesis, modification and application of titanium dioxide nanoparticles: a review

“…Novel MnO@TiO 2 nanoboxes with a porous crystalline MnO core (core size ∼15 nm) and amorphous TiO 2 shell (thickness ∼9.8 nm) were reported by Yang's group using a wet-chemical method (destructive method). 110 The formation process of the nanoboxes is illustrated in Fig. 9d.…”

Dual‐Functional Hosts for Polysulfides Conversion and Lithium Plating/Stripping towards Lithium‐Sulfur Full Cells

“…Interface modification, and structure reconstruction [41,42] from the viewpoint of material‐design, have been proven to be effective ways for the regulation of the Li plating/stripping on anode (Figure 2). For instance, an artificial SEI layer is fabricated on the anode surface by magnetron sputtering atomic layer deposition and spin coating [43–45] .…”

Boosted Polysulfide Conversion by Co, Mn Bimetallic-Modulated Nitrogen–Carbon Material for Advanced Lithium–Sulfur Batteries

“…Therefore, the researchers introduced nitrogen-doped carbon (N–C) with abundant pyrroline nitrogen and pyridine nitrogen structures to adsorb LiPSs Unfortunately, due to the low doping rate of heteroatoms, it is still difficult to overcome the serious capacity fading problem. So, the researchers introduced polar compounds (metal oxides, , nitrides, , sulfides, , etc.) that can form a certain chemical adsorption with polysulfides via the soft acid–soft base interaction between transition-metal cations and S 2– /S 2 2– , making them excellent chemisorption sites .…”
